> Never used coal power: Albania, Cyprus, Estonia, Latvia, Lithuania, Luxembourg, Malta, Switzerland, Norway
Definitely wrong - Malta has used coal power for example. See for example:
"In 1979, a second oil crisis, this time due to the Iranian Revolution, again brought into question Malta’s energy policy and made the government seek alternatives. Between 1982 and 1987, four stream turbines were installed at the Marsa Power Station. This strategy could have worked if the environmental and human health impacts of the coal used at the power station had not caused the local population to protest. In 1987, construction of a new power plant, at Delimara, started; the plant was commissioned in 1994. In the meantime, the Marsa Power Station continued to be improved, with new turbines added to eliminate the use of coal. On January 12, 1995, Malta became independent of coal but consequently became fully dependent on oil."

Moldova has not purchased any energy from it since 2024.

For Sweden, the coal plants were exclusively for cogeneration (district heating with electricity as a byproduct) and only used as peaker plants in winter. Some of them still exist but have been converted to burn biofuels instead, mostly woodchips and other byproducts from the forestry industry.
For most practical purposes, Swedish electricity generation has been basically fossile free since the 1980's.
ggm 5 hours ago [-]
I may be wrong, but I believe the british experience with biofuels is that although you want to believe its surplus byproduct, the cheapest source is often grown to be fuel for a biofuel generator. It's like soy/corn for ethanol, it isn't sufficiently profitable to do this solely with waste product, you get better margins growing to fulfill the contract.
renhanxue 43 minutes ago [-]
That may be true in many places, but the Swedish forestry industry is very big, and the district heating plants really do burn mostly forestry byproducts. Of all the biofuel used in Sweden (not just for energy generation), 75% comes from forestry products, and the vast majority of it is either unrefined wood products or byproducts from Kraft process paper manufacturing (like tall oil and turpentine etc).
Specifically in district heating, 87% of the forestry-sourced fuel is unrefined wood products. Almost half of it is just bark, branches and treetops. Of all the biomass in an average mature tree logged in Sweden, 43% ends up as pulpwood, 43% as saw timber, 8% gets burned for fuel and the remaining 6% is treetops and branches which also tend to end up burned for fuel.
There is definitely a lot of debate in Sweden about sustainable forestry practices, though. The industry really wants to clearcut everything for convenience, but it's really bad for biodiversity and the general public hates it.
Addendum: I believe there's also been some studies and experiments involving importing olive pits from the Mediterranean olive oil industry for burning in district heating plants, but I don't think it's been done at scale.

Depends on the input into growing the biomass. If you are using industrial fertilizers, it's very far from net-zero. Besides that, from my memory there are studies analyzing this and I think they found it's never net-zero.

> For most practical purposes, Swedish electricity generation has been basically fossile free since the 1980's.
I think "practical purposes" should include the fact that thanks to also shutting down a bunch of nuclear, Sweden regularly imports German/Polish coal power.
Sweden claiming fossile free is only technically true. Practically there's a mountain of greenwashing.
So no, I would not say what you just said. I find that greenwashing dishonest.
By being anti nuclear, the green parties around the world have caused more radiation[1] and climate changing co2 than any other movement in history.
[1]
An oft cited statistic is that coal causes more deaths every single year from radiation (excluding accidents) than nuclear has has caused in its entire history INCLUDING accidents.
renhanxue 5 minutes ago [-]
I mean, you can call it a "mountain" of greenwashing but to me it looks more like a mole hill. Total Swedish electricity production is typically 160 to 165 TWh per year and total consumption is usually between 135 and 145 TWh.
In 2025, the net export was about 33 TWh. Gross import from Germany, Poland and Lithuania, including transit to other countries, was 1 TWh. So, imported power from countries with coal power plants was less than 1% of total consumption, and the amount of fossil free power exported was more than 30 times greater than the amount of (potentially) fossil power imported. 2% fossil energy in the mix is to me not really significant, and especially not considering how much fossil free power is exported.
This is true. A nuance often missed. Different rock (that is considerably worse in several ways, needs heavy fuel oil to be added to actually burn and has I think even higher co2 output per unit of energy) but kinda the same.

This is a strange claim. During its peak years - in the mid 1990s - Moneypoint (the only coal plant in the country) provided 25% or more of the electricity mix while wind generation consisted of a few tiny pilot plants - contributing a miniscule.
In 2026, coal now provides 0% of the mix while wind provides 30% or more. Peat burning has also been fully phased out while oil (Tarbert) is in the process of being shut down while Moneypoint has been converted to oil but only participates in the capacity market - i.e. as an emergency/backup source - and so barely registers in the mix.
And even if coal was supplanted one-for-one with NG, it would still be a net win - by halving the CO2 intensity of generation as well as being far more flexible, scalable and much cheaper to deploy.

Calling something a religion is a lazy and disingenuous way to dismiss it. The effects of airborne and waterborne pollution on human health has been the focus of scientific investigation for centuries at least. Ecosystem destruction is not "a religious belief" - it's something which has been measured, carefully recorded and studied using scientific methods.
> at 1/1000th the cost of re-wiring our entire energy system around renewables
This is alarmist hyperbole. Renewables now account for about 35% of the global electricity generation mix. There are countless examples of countries that run grids where renewables account for more than 80% of the electricity mix. Even if you just consider wind and solar, many countries are approaching 50% penetration in the space of 20 or 25 years without "re-wiring their entire their entire energy systems".
Yes NG generation is the only fossil tech still standing in terms of being able to compete at any level with modern generation tech but it is being squeezed.
Batteries surpassed NG in terms of economics for peaking sometime around 2020/2021 - which is reflected by the share of new capacity investment since then.

This doesn't mean what you think it does:
- China is also decommissioning older plants.
- These new coal plants aren't running 24x7
- Peak coal usage is likely to be very soon in China (this year even according to some); after that coal usage flatten and start declining; all the way to a planned net zero in the 2060s.
The newer plants are designed to be more efficient, more flexible, and less polluting than the older ones. They are better at starting/stopping quickly/cheaply. Older coal plants used big boilers that had to heat up to build up steam before being able to generate power. This makes stopping and starting a plant slow and expensive. Because they consume a lot of fuel just to get the plant to the stage where it can actually generate power. The more often plants have to be stopped and started, the more wasteful this is. With the newer plants this is less costly and faster.
This makes them more suitable to be used in a non base load operational model where they can be spun up/down on a need to have basis. This is essential in a power grid that is dominated by the hundreds of GW of solar, wind, and battery.

derriz 12 hours ago [-]
By what measure? Coal hasn't been competitive for decades and the only way it had remained competitive in terms of cost per MWh even back then was if you burned it in huge (> 1GW) plants. 1GW plants are the very opposite of what you want to electrify rural areas - construction is slow and expensive, operating large plants requires considerable and qualified head-count, logistics is an issue and they require high capacity and expensive transmission systems.
And if your minimum unit size is 1GW then you lose the flexibility to roll out the tech incrementally - the average modern coal plant requires 3 to 5 weeks per year for scheduled downtime for maintenance - so your first 1GW coal plant requires a bunch of other generation sources to cover demand during these periods.
Solar and batteries are the obvious solution for rural electrification: scaleable, cheaper/simpler to deploy - no large scale civil engineering involved, trivial to "operate", effective without the support of big transmission systems and it's possible to buy everything off-the-shelf.
cogman10 15 hours ago [-]
I disagree.
Coal requires transport and extraction which are both pretty expensive processes.
In my home town of ~300 people, there was just a couple of houses which used coal for heating. That's because sourcing and transporting coal was quiet expensive.
Electric heating was much more common. Even the old expensive baseboard resistive heaters.
When we talk about extreme rural areas, what you end up finding is solar and batteries end up being the most preferred energy sources. This has been true for decades. That higher upfront cost is offset by not having to transport fuel.
It's why you'll find a lot of cabins in pretty remote locations are ultimately solar powered. This is long before the precipitous price drop of solar.

How is coal cheaper and easier than buying and deploying solar panels and batteries. Both of which require basically zero additional infrastructure to deploy.
Last I checked mining and transporting coal required quite a lot of heavy industry equipment to do even vaguely economically.
If coal was cheaper and easier than other sources of energy, then the US would be building more coal power plants. But even with the Trump administration placing its weighty thumb on the scale to try and “save coal”. Coal plants are still being shutdown due to simple economics.
If existing plants can compete with renewables, to hard to understand how adding the cost of building new plants is going to change that.

It should be noted that the research from this article acknowledges that official Chinese coal consumption figures are often unreliable or subject to massive retrospective revisions. To compensate, the author uses "apparent consumption" (production + imports - exports +/- inventory changes) and power generation data. This methodology assumes perfect reporting of coal production and inventory levels across thousands of mines and plants. Historically, "statistical discrepancies" in Chinese energy data have masked millions of tons of CO2. If local provinces underreport coal use to meet "Dual Control" energy targets, the "flat or falling" trend could be a reporting artifact rather than a physical reality.
The article also notes that solar and wind capacity grew significantly faster than actual generation, suggesting "unreported curtailment" (where clean energy is wasted because the grid can’t handle it). If curtailment is rising, it means the "clean energy boom" is hitting a hard infrastructure ceiling. The research assumes that if grid issues are resolved, emissions will fall further. However, if the grid cannot integrate this power fast enough, the 290GW of coal power currently under construction will be called upon to fill the gap, potentially leading to a sharp emissions rebound in 2026–2027.
Further, a major driver of the emissions drop is the 7% decline in cement and 3% decline in steel emissions, linked to the ongoing real estate slump. This is a cyclical economic event, not necessarily a green technological victory. If the Chinese government pivots to a new stimulus package (e.g. massive "New Infrastructure" or high-tech manufacturing zones) to save GDP growth, the demand for steel and cement could surge again. The research treats the real estate decline as a permanent plateau, but China’s history of state-led investment suggests that industrial emissions can be turned back on by policy shifts.
Further, the analysis focuses almost exclusively on CO2. China is the world's largest emitter of methane, primarily from coal mine leakages. Even if CO2 emissions from burning coal are flat, continued coal production to feed the coal-to-chemical industry (which grew 12% in this report) results in significant methane venting. If you account for the Global Warming Potential (GWP) of methane, the total greenhouse gas trend might look much less optimistic than the CO2-only trend.
Further, the report credits a 3% increase in hydropower for helping suppress coal. Hydropower in China is extremely volatile and dictated by weather patterns (e.g. the 2022–2023 droughts). A single dry year in the Sichuan or Yunnan provinces can force a massive, immediate pivot back to coal-fired power to prevent blackouts. The 21-month trend may be as much a result of favorable rainfall as it is of solar panels, making it fragile and reversible.
Further, the report highlights a 12% growth in emissions from the chemical industry, driven by coal-to-liquids and coal-to-gas projects. This suggests that China is not decarbonizing its economy so much as re-carbonizing its industrial feedstocks. As China seeks energy security to reduce its reliance on imported oil and gas, it is building a massive coal-based chemical infrastructure. These emissions are harder to abate than power sector emissions and could eventually offset the gains made by wind and solar.
Ultimately, China is still the largest polluter (in every sense of the word) by a large margin. It's nice to see them taking steps to curb this, but we should all remember that any environmental benefits are purely coincidental to their goals of energy independence. We should expect them to rely on a diverse mix of sources - including the 8+ "mega" coal power plants coming online every month.

The EU badly wants to make solar panels, cutting edge chips, fighter jets, rockets et cetera - and it simply can't, not at the cutting edge. The US, on the other hand, can make all of those things. It is still behind China in manufacturing overall, but it can still make a lot of the cutting edge, and it is still innovating.
Second, a lot of the EU stuff is already dead and only continues to exist through inertia. The median German cars and machine tools are worse than the median Chinese and they cost far more.
Third, those numbers often reflect the nebulous concept of "value added." Let's take the case of a refrigerator. Chinese company manufactures every technical part of the refrigerator and ships it to their EU business partner for €100. EU partner assembles it, fills it with foam, and sells it for €600. Most of the "value added" was in the EU! Win for the EU! Go EU manufacturing! The concept of "value added" is the basis for the entire EU VAT system and much of its economic indicators and incentives, while in the US it is almost never mentioned. This is also the source of the most hilarious comparisons (Greek manufacturing superior to the US per capita? χαχαχα)
If you want to cut through the bullshit, you have to look at actual things made. Among the US/CN/EU, who leads: Solar panels (CN), cutting edge chips (US), chipmaking equipment (EU), jet engines (US), aircraft (US), space launch vehicles (US), fighter jets (US), batteries (CN), nuclear reactors (CN), submarines (US), advanced missiles (US), cars (CN), CNC machines (CN), machine tools (CN), precision bearings and linear motion systems (CN), cutting edge medical equipment (US), gas turbines (US/EU), high voltage grid equipment (CN), telecom equipment (CN), construction equipment (US), ships (CN), advanced optics (EU), electric motors (CN), steel (CN), aluminum (CN), oil (US), cutting edge pharma (US), industrial robots (CN), wind turbines (CN), trains (CN), agricultural machinery (US/EU), drones (CN), smartphones (CN.) From that list, China leads eighteen, the US leads eleven, the EU leads two, and the EU and US are tied for two. And China is closing in fast on chipmaking. When China takes that crown, what will the EU have left?

Because coal desposits in the ground have bits of Uranium and Thorium which are radioactive, they get concentrated in coal fly ash, and blow out the chimney in the smoke from a coal power plant, and kill people, they leach into the soil and waterways, and kill people.
That is, nuclear power plants only kill people by radioactivity in the case of an accident. Coal power plants do it in normal operation. As well as coal dust having a PM2.5 dust problem which kills people.
Make it about nuclear vs coal because people say coal is better than nuclear because it's not scary radiation, and it actually is.

Nuclear generates more power from a Kg of fuel, with less CO2 pollution and fewer deaths. It's not bad, but even if it was bad it's not "both sides", it's much less bad.

With Nuclear energy, let's face it. If you have a nuclear plant running, the input is just some uranium which we have plenty of. Thereotically we have no problem with running at peak power production.
You are also forgetting that Sun can be blocked during times of rains and Wind is unpredictable as well.
If you can work with solar panels only that's really really great. Unfortunately that's not how the world works or how I see it function :(
You are forgetting that markets operate after work and the late night culture and so many other things. You need lights at energy and quite a decent bit. You are also forgetting that if we ever get Electric vehicles then we would need energy during late night as well.
A lot of energy in general is still needed during nights and would we be still burning coal for that?

Its not just about enough sun and wind capacity. There is already over supply in lot of the world. But the supply curve doesnt match the daily DYNAMIC demand curve so grid ops still dependent on coal and gas for different reasons. It becomes about what happens during unpredicted demand spikes, or when congestion on those wires happens whose load gets priority? which producers get curtailed? etc etc That moves probs into the political domain. You can watch daily grid ops live and see the probs. Wars and the weather randomly take down wires and substations all the time. If you can move people and factories to follow the wind and the sun then maybe you get demand and supply curves to match easier.

I can be wrong but you would probably lose tons of efficiency even within High Voltage DC lines if everyday late night we take energy from different countries. Also this is getting outside of topic of discussion for me because one of the reasons we want Nuclear or Green energy in general is also the environmental plus the sovereign plus the long term affordability plans.
Another point from your first comment but if we run peak production in nuclear say in a country A, then the country A can also give power to Country B at late night similar to what you are proposed for solars.

Once again, within my first comment I raise issue of battery. You mention a comment and I respond and then we get to batteries again.
I have no problem with solar at all without batteries but batteries really flip the equation in terms of environmental concerns.
My question is plain and simple, Why not Nuclear? I understand, I am not against Solar. Although environmentally, I feel like battery is a valid concern.

Maybe, but I think that, I can speak about the problem within US which I can better explain but US had nuclear fearmongering attempts and Senators passed laws which increased regulations on it to the point that some regulations contradict past regulations.
Nuclear power plants being built on loan in such a flimsy regulatory market was what lead to the downfall essentially within US
Nuclear fearmongering and lobbying efforts from Oil Industry as they are one of the most strong opposers of nuclear energy[0]
Once again, how do I explain this but nuclear produces 3.2x less carbon emissions than Solar[1]
We are able to build hydropower plants, we are able to launch spaceships into moon and outer space. It's definitely possible to build nuclear if lobbying effort decreases.
I'd say that its our dependence on Oil and Coal which have been the problem. I have nothing against solar and that is something that I am saying from the start. At some point we should look towards transition towards nuclear as well. To give up on that would simply not be ideal.
> I can't speak about UK but considering how cheap Uranium is, can UK not do cost analysis. Uranium is abundant material compared to Oil/Coal.

Alright, So I think that some/most of my talking points were very inspired from the michael moore's documentary on the topic and I re-watched it after reading your comments. (Although Michael doesn't talk about Nuclear in the shortcomings)
I was going to ask you 3-4 questions but then I searched them upon myself and I do think that the results are more (positive?) than I thought.
Solar could feed world's energy needs by 0.3% and I think that Excess Solar could be used for green Hydrogen etc. too when needed for burstable energy source and smart grids in general to fix the ramp-up/ramp-down problem
I think one of the only things that I was sort of worried about mainly was the fact that Batteries produce lots of Co2 emissions and harm to the planet when mined but it seems that they have lifespan of about 10 years and can be carbon negative 3-4 years.
I don't know, I go through waves of doubt over Solar. I might need to learn more about Solar because I feel like I can just agree to whatever side I hear the recent data's from. Lies, Damned Lies and Statistics it seems.
But I feel like although solar is right direction too, we probably need smarter grids and just improvements within grid infrastructure in general too. Another point about Solar could be that there can be a more personal adoption of it whereas I can't build my own nuclear power plant so I do agree with you.
I'd still say that there is a lot of greenwashing in the Climate Change community to treat wood-chips and trees as fuel source and all the problems that stem from that with timber industry.
So although there are short-comings in Solar given its intermittent nature. I do agree that unless Govt.s create nuclear, it could be a good bet for personal actions/ even Govt.s to diversify at the very least from Oil.
I still think that though there is something wrong where People are wrongfully worried about nuclear. India for example had 3% of its energy coming from Nuclear and I looked at wiki and we planned even more but anti nuclear protests started happening after Fukushima Disaster :(
I am still really interested about Thorium Reactors and the race towards building it though. They are mostly disaster-free and Indian in particular has quite a large reserve of Thorium (25% of the world supply). The govt. is working on making 100GW to raise thorium's ratio in energy to almost ~10% estimate from 3% till 2047 which would still be impressive given that total energy would skyrocket as well till then.
India has true chances of being Energy Independent long term if it focuses on nuclear and Solar both rather than focusing on Solar given any advancement in Thorium reactor will be huge for us. For reference Coal : Thorium power ratio for same mass is 1:3.5 Million and its even more efficient than Uranium.
Also Thorium cannot be used for Nuclear Bombs in the sense of a fission unless you drop it at someone complete point blank but at that point its worthless compared to missiles so we can genuinely share this technology all across the world.
Thorium Reactors long term feel the future to me. So maybe I am too bullish on Thorium.
Solar is nice but atleast personally, Investments in Thorium Reactors could make India Energy Independent given 25% of the supply. We also recently found a huge jackpot in lithium and other minerals in Kashmir recently so I suppose long term India can be sovereign in manufacturing batteries for Solar production as well.
There is such a massive possibility in nuclear especially more so for India and general consensus also being within Scientific community that nuclear energy is cleanest forms of energy. The Combination means that, I'd want my govt. to take some risks in nuclear research/projects given how big the reward can be and that's also why I vocally support Nuclear. Much more than Solar. But I'd say that any govt. has their own risk profile and maybe Solar can be boring but works technology for Energy Independence so I just hope that Solar & Thorium both show some good numbers long term as well. So it isn't as if I am anti Solar as much as I am very pro nuclear energy long term.
Because nuclear is too good to be true, which makes it the preferred ragebait for many, it seems

Overall Result (Typical Modern Coal Plant)
When multiple systems are combined the percentage of things filtered out is:
The goal of net energy exporter assumes that energy produced at one time can be exchange for energy produced at an other time for the same price, and that assumption has not been true in Europe for decades. You can be a net energy exporter and still be dependent energy imports for more than 50% of the energy a country consumes, as has been demonstrated by Denmark.
I will happily trade 10 unit of energy for just a single unit of energy, assuming I get to decide when I give the 10 units and when I can demand the 1 unit. A lot of profit in the European energy market can be made by such a "bad" deal.
The date when a country energy grid is free from fossil fuels, like coal, is when the grid has no longer any demand during the year for producing or importing energy produced by fossil fuels.

True.
But: EU is the only effective player in the world that drives energy policy outside its borders, by being a massive market with regulatory power regarding its imports.
If you look at three figures: energy use per capita, emissions per capita, and GDP per unit of energy/emissions, and include imported consumption, the EU's are all trending in a positive direction for many years now.
So stating the EU has de-industralized and its progress on shutting down coal is therefore 'fake' and misleading because it imports its industrial consumption from other countries to which it has simply offloaded its emissions, isn't true.

I don't know if I buy this argument. If the US sends oil to another country, which burns it for energy, produces a finished good and exports that back to the US, then the CO2 released isn't accounted for in production-based numbers. But it seems to me like it isn't really properly accounted for in the consumption-based numbers that Noah is holding up, because those are effectively giving the US a credit for exporting the oil in the first place that offsets the imported good. As he says, the US's exports are carbon-intensive and that largely explains the difference being so small.
Noah also tries to refute the perception that manufacturing is in decline in the US, but he doesn't adjust per-capita and doesn't account for the obvious fact that major US exports are looking more and more like raw materials and less like finished goods, while imports are the other way around. Aircraft and ICs used to compete for top spot on the US export list. Since 2008 it's petroleum and oil.

This is generally overstated. Emissions imported or exported via trade are significantly smaller than domestic emissions for almost every country. In the EU vs China case, accounting for imported/exported emissions basically changes which of the two is doing better, but emission levels are pretty close to begin with (US is already doing significantly worse than China either way).
For China, we are talking about ~1 ton/person/year from trade (in favor of China), while local emissions are at ~8 tons/person/year [1].
You make a valid point, but looking at the actual numbers it turns out that this makes (surprisingly) little difference.
This is what matters. The whole thing is an exercise in greenwashing. It doesn't matter if you stop burning coal in your own country, if the energy you import is also made by burning oil and gas.
The whole conversation about clean energy is polluted by the complete misunderstanding of the general population of how energy demands are balanced. Saying you're replacing coal and gas with wind is just nonsense. It's one solution to a bigger problem. The big problem is how to balance your grid across peaks and troughs and that requires a diverse set of clean energy solutions, with wind being one small part of it.

The actual causes of electricity cost rises in Ireland being higher than Europe are:
Lower population density on a grid without good connections to neighbours.
Previous underinvestment in network infrastructure.
Gas price rises combined with Ireland having less renewables that the EU average (middle of the pack for electricity, 3rd from bottom on total energy).
Maybe saving the world a bit harder would have helped keep prices down. It's certain that building more renewables now is the likeliest path to cheaper electricity.

Wrong comparison. Most of Europe has way too high electricity prices.
It seems logical that ending the use of existing coal energy infrastructure puts upward pressure on prices. Coal is cheap, abundant, energy dense.

Only if you externalize environmental costs. The point is that coal is actually really expensive.

Oh, and the power to make PV panels...comes from coal. On the other hand, if you just put a windmill next to an Irish politician, you could power the entire country.

hunterpayne 14 hours ago [-]
No, that's wishful thinking. You can have your own opinion, but not your own facts. Engineers actually calculate all this stuff. EROEI for instance means Energy Returned on Energy Invested. For renewables, its 4. That means under ideal conditions (albino of 1, 20 year lifetime), over the lifetime of the panel you get back 4x the energy that it took to extract the materials, make the panels and install them. So if you site the panel somewhere with an albino of .25 (Spain) you get about as much power out of them as they took to make and install. And that obviously doesn't actually help with AGW.

The ERoEI numbers seem to be under some dispute. This study estimates it at 9-10 in Switzerland.
Also you mention albino and I can't find what that would mean in this context. At first I assumed you meant albedo but that doesn't seem to contextually match either. So I might just be misunderstanding your post.
NoLinkToMe 49 minutes ago [-]
I think you don't know what you're talking about.
For one the EROEI isn't 4 for renewables under ideal conditions, it differs wildly depending on the type and location and installation. It's true that for solar in Ireland (which are NOT ideal conditions) its on the low end, though still about twice as much as 4, and it's certainly not the case for wind which can have them as high as 20.
Second, I've got no clue what 'albino' is. Do you mean albedo? In that case, it's completely irrelevant for wind power. Ireland produces 20x more wind than solar, the latter is completely irrelevant in Ireland.
For solar albedo is relevant, but only if you have bifacial panels, which are still the minority.
In Spain albedo is relatively low but it has some of the highest direct sunshine hours in Europe. Albedo is high in places like the Nordics, which have fewer sunshine hours. In other words, EV is brilliant in Spain due to the abundant sun, yet surprisingly is still viable in a place like Norway precisely because of relatively high albedo, not in spite of it. This is why EROEI for solar in Spain can get up to 20. The idea that you get as much power as it took to make (EROEI of 1) is so wrong, and so obviously wrong, that it seems like you just don't have any idea what you're talking about.

An of EROI of 4 would probably already include the poor sunlight conditions of Ireland or would be some old numbers based off old solar technology. Plus there's contention around EROI because it does ignore the fact that renewables can be recycled and many are used past their lifetimes, and of course it ignores the negative externalities of spewing the one time use fossil fuels into the atmosphere. There are plenty of studies and papers arguing over EROI and its veracity.

A quick Google shows EREOI of solar panels at 10-30 depending on study.

The PV manufacturers themselves say its 4. Those studies you mention say you could make them at 10-30 in theory if you could somehow purify the poli-silica differently. If we made PVs in the west with natural gas (and carbon recapture), perhaps it could get to that number (but perhaps not). However, PVs aren't made in the west and the poli-silica isn't purified with gas but instead using coal. That's why those numbers are different. And for reference, we could have made those PVs in the west, however politicians chose not to.

How close are Ireland to 100% wind during optimal weather?
Macha 14 hours ago [-]
In 2023, peak renewable generation capacity was 75% of typical energy demand:
For actual generation over a longer time period, in February 2026, 48% of energy used was generated from renewable sources, of which the vast majority (41% of energy use) was wind:
With 75% in 2023, it means there are still headroom for expansion without hurting the economics too much of existing wind farms. Denmark had a very clear growth of wind farms up to about 100% of demand during optimal weather, and then a very clear stop in growth afterward. On average it still only produce about half the energy consumed in Denmark, so over time I do not expect to see Ireland to go much higher than 50%. It might get a slight advantage given the improved wind farm technology to utilize low wind conditions.
I do see in the political goals for Ireland that they, like Germany and many other countries in EU, are relying on the idea to turn wind into green hydrogen once they hit that 100% during optimal weather. Peoples faith in that strategy has gone down significant in the last 5-10 years.

Now this is just moving goalposts. The comment I replied to stated that the problem with renewables was that they too pollute and cause waste that isn't easy to dispose of, and they also affect the environment in a negative light. I didn't even dispute that point, as I said renewables aren't a silver bullet and we should be pursuing as much variety as we can with our energy production & grids, whether it be fossil fuels, renewables or especially nuclear. But we should preferably be moving more towards the latter two and away from fossil fuels except in situations where they make the most sense, and also considering all the facts that usually get conveniently ignored when discussing fossil fuels, like their disastrous effects on the environment.
> The EROEI of renewables is 4
Saying "renewables" have an EROEI of 4 is disingenuous at best. "Renewables" isn't one technology, it covers everything from wind to solar to geothermal to hydro. That 4 figure comes from worst-case transitional modelling of buffered wind specifically, and even then it's a temporary system-wide dip, not a measurement of what these technologies actually deliver[1]. Wind and solar individually come in at >=10:1 and rising as the tech matures[2]. Geothermal actually is in the hundreds, but that obviously isn't globally applicable. Lumping all of that together and slapping a "4" on it is either ignorant or deliberately misleading.
And the "hundreds" figure for fossil fuels is pure fantasy. Conventional oil sits at roughly 18-43:1, and US fossil fuel discovery EROI has cratered from ~1000:1 in 1919 to about 5:1 in the 2010s[3]. A paper in Nature Energy last year took it further and showed that when you measure EROI at the useful energy stage - accounting for all the waste heat from combustion - fossil fuels drop to about 3.5:1, while wind and solar beat the equivalent threshold even with intermittency factored in[4]. So "the laws of physics" are actually making a pretty strong case for renewables here.
> If you want solar PV to help with AGW, they must be sited somewhere with an solar albino > .25
I think you mean albedo. And that claim has been tested[5], a satellite study of 352 solar sites found the actual albedo reduction was much smaller than what's typically assumed, and the warming effect was offset by avoided emissions within roughly a year at most sites. A separate study of 116 solar farms found a net cooling effect on land surface temperature[6]. The idea that solar north of Barcelona is "making AGW worse" just doesn't survive contact with the data.
> ...but they don't care about your politics (or mine)
What a deeply unserious tone to take in a discussion like this. Where in my comment did I mention politics of any kind? Is any mention of renewables in a positive light political to you, or is it where I questioned whether the same scrutiny gets applied to fossil fuels? Because that's not politics, that is just reality which you seem to care so much about.
Newsflash, you don't need to be a leftist (which is what I assume you're insinuating) to realize that relying solely on a very finite, heavily polluting fuel source that has already caused disastrous effects to the Earth is maybe not the smartest long-term play. That's not politics, that's just common sense and basic risk management. Not to mention the decades of propaganda, lies, bribery and other bullshittery that big oil has wrought upon us. You'd think people who call themselves true conservatives and free-market capitalists would be the first ones evangelizing against all of that, but apparently not.

There’s the direct answer to your question, cost of installed grid battery storage are getting cheaper by the user and it’s completely viable option at present. It’s not some vague fantasy idea like power plants in space or something, just look at California’s energy mix during peaks that in just a few years has become dominated by solar+batteries.
For longer periods of low-sun in a climate like Ireland see the other renewable options he mentioned. Plus a couple natural gas plants for fallback that can comfortably sit idle until needed.
If some combo of renewables are used 90% of the time when possible, no one is going to be mad about modern clean-burning LNG plants compared to a toxic, expensive relic of the past like coal.
Current trends make it clear the future will be renewables, grid battery storage, and however many natural gas plants are needed for reliability based on local climate (plus keeping nuclear online if you already have it). And that “future” is pretty much here already in places like California.

And it will only become more cost effective over time thanks to economies of scale.
CA has just started bringing grid storage online in the last few years but it’s already making an appreciable difference during peak times that in the past years resulted in blackouts.
It shows the clear, achievable path to a renewable + battery (+ nat gas) future that’s 95% renewables and highly resilient. Grid storage isn’t a “10 years away” fantasy like anti-renewable advocates might wish and it’s the critical piece to make those plans possible.

If you're going to make that comparison, you need to compare apples-to-apples and include solar efficiency in the coal too. After all coal's energy originally came from the sun. Plants converted the sunlight into energy at an efficiency of about 1%. A miniscule fraction of that energy went into the plant growth, and then a miniscule fraction of that energy was captured when the plant was converted into coal.

>Coal is cheap
No it's not. I'm not talking about the environment either, coal plants are just straight-up more expensive than gas plants and renewables.
Coal plants are necessarily steam turbines and not internal combustion, because coal is filthy and the mercury/sulfur/etc would wreck the guts of any machinery it goes through. Thus, it's only used to boil water.
Gas turbines don't have that problem, so they spin the turbine with the combustion products directly. They're far more efficient, the machines are smaller and cheaper, and because you don't need to wait for a giant kettle to boil before ramping up the power, they're far more flexible and responsive to demand. It also helps that the gas is fed with a gas pipe, whereas coal needs to be fed with a bobcat.
Which is why nobody is building new coal plants - they're way more expensive than gas plants, even if the gas fuel itself is more expensive than coal.

China is building everything at a pace never before seen in history. Partly because their construction industry is a jobs program, and their economy is so dependent on it that they prefer building things at a loss rather than not building at all. Which is financially dumb, but welcome to politics.

Some figures on running costs:

As a fossil fuel comparison, Gas costs about £114 per MWh.
Nuclear - Hinkley C will cost about £128 per MWh - but likely to be even higher when it comes online. And we will be on the hook for this price as long as it runs, no matter how cheap renewables are.
AnthonyMouse 15 hours ago [-]
> As a fossil fuel comparison, Gas costs about £114 per MWh.
You're comparing the cost for coal as baseload to the cost for natural gas as a peaker plant. When using both for baseload, natural gas is cheaper than coal and emits less CO2.
Meanwhile renewables are cheaper than both until they represent enough of the grid that you have to contend with intermittency:
Which doesn't happen until it gets close to being a majority of generation, and which most countries aren't at yet so can add more without incurring significant costs for firming.
In other words, the currently cheapest way to operate a power grid, if that's all you care about, is to have something like half renewables and half natural gas. Add some nuclear -- even just, don't remove any -- and CO2 goes down by a lot because then you're only using natural gas for peaking/firming instead of baseload, while still having costs in line with historical norms.
The obviously bad thing many places are doing is shutting down older power plants without building enough new capacity in anything else to meet existing demand, and then prices go up. But that's not because you're using e.g. solar instead of coal, it's because you're trying to use demand suppression through higher prices instead of coal. It's easy to get rid of coal as long as you actually build something else.

Yes, all three. Building a nuke plant without the additional concern for outcome that we put on nuke would be relatively inexpensive. It's just concrete, pumps, and a turbine. It's a ismilar level of complexity to a coal plant. Same with running cost, same with decommissioning costs.
Suppose we designed, operated, and budgeted every coal plant to make accidents like this a statistical impossibility. Not very unlikely, that's not the standard we hold nuke to. An impossiblity. Imagine what that would cost.

A nuke plant is concrete, pumps, fuel storage and (re)processing, a huge pressure vessel, some very complex moderator machinery, and some of the most complex industrial plant control on the planet.

AnthonyMouse 15 hours ago [-]
"Fuel storage and reprocessing" isn't that much of the cost and a significant proportion of that is compliance costs and extreme safety measures. The pressure vessel is likewise a small minority of the cost.
Industrial control systems are fundamentally sensors, actuators and a computer. None of those is actually that expensive. Nobody should be paying a billion dollars for a valve.
Older reactors have somewhat high operating costs because they're so old, many of them were built more than half a century ago. Newer reactors often have higher costs because of the lack of scale. If you only build one or two of something you have to amortize the development costs over that many units, mistakes that require redoing work are being made for the first time, etc. Build more of them and the unit cost goes down.

AnthonyMouse 4 hours ago [-]
"Decommissioning costs" are essentially bad math. Here's this again:
Nuclear, inclusive of construction costs: ~$181/MWh, only better than natural gas because no CO2. Nuclear, cost of continuing to operate an existing reactor once it's already built: $31/MWh, basically the cheapest thing on the market, half the cost of continuing to operate an existing natural gas plant (because you need so much less fuel).
What this implies is that if you build a nuclear plant you're going to want to continue operating it for 80 years, and even then you probably want to just modernize it again instead of actually decommissioning it.
The long-term average returns from ordinary investments (e.g. S&P 500) are ~10%/year, implying that even if you require decommissioning to be prefunded (unlike any competing form of power generation), the amount of money you need is less than 0.05% of what the cost will be in 80 years. Adding $500 million in decommissioning costs isn't $500M in net present costs, it's only $250 thousand in net present costs, because you take the $250k and add 80 years worth of interest (1.10^80) which multiplies your starting capital by more than a factor of 2000.
It's really just the construction, and that's in significant part because you have to build more of them to get economies of scale for building them.

This is disingenuous. Bad math is focusing on the one part of nuclear power which is relatively cheap (fuel) and ignoring the rest where the majority of the cost is, which is what you did.
I wasnt comparing nuclear power to gas anyway I was comparing it to solar and wind which produce no CO2. FIVE times cheaper LCOE.
Nuclear power needs anyway to be paired with dispatchable energy source like batteries or gas just as solar and wind do.
It isnt a competitor with gas or batteries it is a complement to gas and batteries, just like solar and wind.

The argument that Ireland’s high costs are primarily due to low population density is a common oversimplification. While Ireland is rural, countries like Finland and Sweden have significantly lower population densities and more challenging geography, yet they consistently maintain lower residential and industrial electricity prices. The issue isn't where the people live. It's the gold-plating of the network. Ireland’s regulatory framework allows EirGrid and ESB Networks to pass massive capital expenditure costs directly to the consumer with guaranteed returns, leading to a build-at-any-cost mentality that density doesn't justify.
The claim of "previous underinvestment" ignores the massive capital outlays of the last decade. Ireland has actually seen massive investment in its grid to accommodate renewables, but the efficiency of that spend is questionable. We have a "constraint payment" system where we pay wind farms not to produce power when the grid is congested. In 2023 alone, these payments reached hundreds of millions of euros. This isn't "underinvestment". It's an operational failure to align generation with grid capacity, a cost that is hidden in the consumer's bill.
You suggest that "saving the world harder" (more renewables) would have lowered prices. This ignores the Marginal Pricing Model. In the Single Electricity Market (SEM), the price of electricity is set by the most expensive generator needed to meet demand - which is almost always a gas-fired plant. Therefore, even if wind provides 80% of the power at a given moment, consumers often still pay the "gas price" for all of it. Adding more renewables without reforming the marginal price auction system does nothing to lower the immediate cost to the consumer. It just increases the profit margins for renewable operators.
I should also comment on the source of that report: Nevin Economic Research Institute (NERI). NERI is not a neutral academic body. It is the research arm of the Irish Congress of Trade Unions (ICTU). NERI’s research is fundamentally rooted in Social Democratic and Labor-centric economics. Their reports consistently advocate for increased public spending and state intervention. By focusing on "underinvestment" and "network costs," NERI shifts the blame away from the policy failures of the green transition and toward a narrative that justifies more state-led infrastructure spending. They often downplay the impact of aggressive carbon taxing and the "Public Service Obligation" (PSO) levy, which are direct policy choices that have inflated Irish bills compared to the EU average.
Finally, the "poor connections to neighbors" argument is becoming obsolete. With the Greenlink and Celtic Interconnector (to France) coming online, Ireland is becoming one of the most strategically connected islands in Europe. If isolation were the primary driver, prices should be falling as these projects near completion. Instead, they remain the highest in the EU (often 40-50% above the average). The "island" excuse is a convenient shield for domestic policy inefficiencies.

They must have been real quiet. Most the protests are related to how expensive it has become to rent / buy in this country.
Ireland has encouraged and allowed a huge number of data centers to be setup here and been very slow to implement legislation for other green forms of energy generation. We don't need dirty forms of energy production here like coal and peat just to make energy cheap. Relying on Oil and Gas leaves us hugely at the whims of the international markets.

Sorry I missed your question.
While being a tax haven was part of Ireland’s strategy, given we have little natural resources for export or refining for heavy industries, we also have a well educated workforce which spoke English as a first language and were once cheaper than British workers and also, enthusiastically part of the EU. So we built up a service industry and high tech and high value industries like pharmaceutical and IT. We no longer are the (in my view once somewhat shameful) tax haven we were but now are low tax in a much more fair way (probably could be better but all countries are working the system). Opinions differ. But Ireland is genuinely wealthy and productive. We have serious problems with inequality and a stupid housing problem in the bigger cities. Nevertheless, compared to most of the world and compared to the Ireland of my youth it’s a great if imperfect place where you can have a great quality of life.

A very fair question and the answer is complicated. Production costs and transmission costs are separate. Also demand changes the market rate.

> This is to incentivise the cheapest production methods to be invested in.
It's also just a rule of economics. The price is set at the cost of the most expensive production necessary to meet demand.
So if solar could fulfill 100% of energy demand, price would be the cost of solar, and any other more expensive generation would either lose money, shut down or idle.
But if we shut down or idle those today we wouldn't have enough electricity, so the price rises until the more expensive plants can stay open and demand is met.

Because at the moment wind has been the winner in the Irish climate, especially when you look backwards long enough to account for the time scales over which energy buildouts occur. Renewables have grown to 40% of the overall supply, resulting in the most expensive plants (currently coal plants, and before that peat) closing. Solar is entering the market rapidly though, it grew from like 1% to 4% in the last 3 years.

It is not that complicated. When the energy crisis in EU happened a few years ago, it demonstrated clearly that people and industry is willing to pay a years worth of energy bills for a single month to keep lights and machine operating. What this mean is that you could in concept give people free power for 11 months, and then increase electricity prices by 12x for the remaining month, and people would still pay it.
This also demonstrated through most countries in Europe that citizens will vote to have government that fix the energy market. Citizens do not want a free energy market that can raise prices to any degree, and its their tax money that fund grid stability.
This all mean that the cheapest form of producing energy do not result automatically in reduced energy costs for consumers and companies. The product that people pay for is not energy in a pure form, it is energy produced at a given time and given location. Make the energy free but the time and location expensive, and the total cost will still be expensive.
Transmission can help Ireland, but it can also hurt it by linking it to a larger market that can create a even higher demand spikes than exist in the current local grid. If the linked grid has locations which has higher energy costs than Ireland, then Ireland will subsidize those people by linking the markets together. Rules like highest price regardless of source sets the price, and higher amount of transmissions, also tend to result in more companies getting paid to maintain operations and thus more parties getting paid that is not linked to the marginal cost of producing energy.
Spooky23 19 hours ago [-]
It's really not. Energy grids are not designed for distributed generation. In my US state, that means billions of infrastructure investment.
The people using carbon to create forcing functions to transition to renewables conveniently forget to mention that. Which sucks, as solar in particular is almost a miracle product, but at this point my delivery charges to get electricity exceed the electricity supply by 10%. 20 years ago, delivery was 30% of supply.
My state, New York, decided it would be smart to turn off the nuclear plant that supplies 20% of NYC electricity, and replace it over a decade with a rube goldberg arrangement of gas, offshore wind, solar, and Canadian imports.

Mostly because marginal pricing/merit order.
In a vast over simplfication, the most expensive producer that gets to supply sets the overall price. So even if you supply 99% from wind and hydro, the 1% of power that comes from gas sets the price for 100% of the electricity in the market.
When gas gets more expensive, electricity from gas gets more expensive. The more you have to rely on gas (because you don‘t have batteries, not enough solar, etc), the more you pay high prices.
There are different ways to address these issues. Demand side load management, batteries, etc.
Macha 19 hours ago [-]
Solar is priced based on gas prices as a financial incentive to encourage producers to build solar. That’s because profiting from the difference between the cost of production for solar and the cost of production from gas is supposed to be the incentive to build solar.
The gas prices went up massively in 2022 with the war in Ukraine, and even though that subsided before the war in Iran a little, the existing supply companies are not going to give back an increase in the price they’ve gained because their prices dropped.

That’s why they are installing it all over their country at the fastest pace of any country by far? That’s why they probably hit peak oil consumption?
The coal thing is complicated in China. They are replacing many old coal stations, local governments are fearful of being caught short in a cold winter which has happened. Rate of coal consumption increases is slowing. Peak coal may have happened last year.
>"China is the world's top electricity producer from renewable energy sources. China's renewable energy capacity is growing faster than its fossil fuels and nuclear power capacity.[1] China installed over 373 GW of renewables in 2024, reaching a total installed renewable capacity of 1,878 GW by the end of the year.

I think the real takeaway here is that the world depends on the industrial production of China, which is powered by coal. We are all using that coal to buy cheap Chinese manufactured goods, and the sooner we come to terms with this the better. Whether a single country uses coal or not is irrelevant for tackling carbon emissions, if we're all basically exporting our carbon emissions to China.

That they have the internal political means to get large infrastructure projects done is laudible - they can actually build transmission lines that make unreliable energy sources like solar and wind feasible. In the US that is effectively impossible due to the NIMBY legal situation.
That they lead in battery production is going to be pretty interesting to watch. I admit I was skeptical that current battery tech could be scaled up enough to make it financially doable, but China is very close to making me wrong on the topic. If they can be the first to truly seasonal storage that works without hand-waving games like pretending you can "just use another source" when you run out of storage I'll be very impressed.
They seem to understand that you need to back unreliable sources with reliable sources - and have the political means to build a coal plant that will sit idle 95% of the time.
No other country is close - it's parlor tricks at the moment. China seems to understand how energy works, and that you need a reliable grid to run an industrial economy. They are very much being pragmatic in how they are building out everything they possibly can. The West has forgotten this.

By 2020 it was obvious that wind & solar were viable long term, so investments in nuclear et al dried up. But they weren't convinced that batteries were viable long term, so they built a lot of coal peakers for night power.
By 2025 it became obvious that batteries were more viable and cheaper than coal peakers, so they've started to build battery storage at a vast scale.

Back in days of yore (2006/07) I read a well-argued policy paper from a quango that no longer exists where it pointed out that Ireland was one of the most fossil fuel dependent nations in the world (particularly due to oil imports).
Our energy prices first spiked around the same time, to "incentivise competition" in the words of a minister of the time.
All the while we have vast, vast reserves of potential wind energy sitting unused because of (mostly) grid and permitting failures. This was and is entirely in our control, but the government(s) (even with the sad exception of the Greens) simply haven't put enough resources into it (although the grid is getting investment, we need a lot more).
Also the critical infrastructure bill will (supposedly) help, but I'm sceptical as none of this ever seems to help.
Which is to say, that I completely agree with you that the costs here shouldn't be born by the poorer people in Ireland, and we need a whole of government approach to driving down the price of energy. This will take time, but the best time to start doing this is now.
My personal belief is that we should also aim to drive down the price of land, as the two biggest costs (for many countries) are land and energy, as they input into almost everything, but reducing land prices is a lot more controversial than reducing energy prices so we should start there.

From what I understand Ireland has very little natural gas, very little coal and a not particularly large amount of peat. If they didn't shift towards importing all of that would be gone in the very near future.

For practical purposes no coal. There are no working coal mines in Ireland, and Moneypoint would have run entirely on imported coal since it was built. It was built with a bulk handling terminal for this purpose (very visible in photos of the plant: https://esb.ie/news---insights/inside-esb/moneypoint-power-s...).
Note that it doesn't have a rail link; even if there had been the desire to use domestic coal and someone had gotten a mine going, there would have been no way to get it there.

The only part of your bills that could be regarded as virtue signalling is the carbon tax, which is driven by government regulation. The vast increases in energy costs were driven firstly by Russia (when they invaded Ukraine) and the US (when they attacked Iran).
And this hits me too, I have (unfortunately) oil heating which has gone from about 500 to 800 over the course of the last week. Fortunately we filled up last month, but it's really worrying.
Ultimately though, the only way to fix this is to build a lot of wind (industrial scale) and solar (residential scale) as otherwise we're at the mercy of world events.

I'd add that this is only part of the equation because: what do you do on an overcast day with no wind?
You need significant storage capacity before you can become isolated from world events. Until then, you need power generation that you can bring online on short notice: coal, gas, hydro, etc. Traditionally, gas was used for this because it's easy to store, quick to get going and gas plants can also burn coal if needed.
Unfortunately, the nice properties of gas (easy to store and transport) mean that it's a global commodity. It will go where they pay the most, which means that far away events can cause a price in gas prices globally.

Per ton, yes. In practical, it’s far more complicated. Ships turn “heavy fuel oil” which is one tiny step from crude. It’s literally the byproduct that we have no better use for except for extremely large slow diesel engines.
If the tankers had to burn more useful fuel, we wouldn’t do it. The emissions on this unrefined bulk fuel is extremely bad.
Rail competes for efficiency depending on sea factors, and truck never does. But mining locally is far far more efficient that shipping literally to the other side of the world on ships that are burning 45 tons of fuel per day.

Wrong. As you can see Ireland always produced a very limited about of electricity from coal, around 11% ten years ago when wind was 10% less. In other words, wind simply replaced coal, not imports.
For the last 50 years gas provides the bulk of your electricity, but Ireland produces virtually no gas and has always imported it. The jump in prices was due to these gas prices increasing due to the Russia/Ukraine war as of 2020, it had nothing to do with import changes. Had you invested more in wind/solar, you'd be affected less.
In fact Ireland barely imports anything at all, over the last ten years the net import are close to zero. 2025 was a peak year for imports but even then imports constituted a small 13%, whereas 2024 was a year where Ireland was a net exporter, as was 2020, and 2016, 2017, 2018, 2019. In fact of the last ten years it was a net exporter 7 times, more than twice as often as the 3 years it was a net importer. And its imported when the UK has cheaper electricity prices, otherwise there'd be no reason to import.
So your entire argument isn't true. Wind/solar can beat coal on a cost-basis now, evidenced by the fact that the average existing coal plant isn't running half the time because it's more expensive, let alone building out more coal. The smartest thing to have done is mass-invest in solar/wind in a country with a population density 4x lower than the UK.

Maybe, like everything else in life, it's a complex series of tradeoffs, costs, and benefits, and you decide whether the cost is worth the benefit.
And if a policy being pushed doesn't make sense when all the costs and benefits are accounted for, then someone is doing something shady and making a shit ton of money, especially if there's a huge amount of smoke and mirrors and politicized talk.
Ireland's being used for things and it's obvious those in power don't care about and don't think the Irish people being affected by these sorts of policies can or will do anything about it.

Electricity generated from peat peaked at 19.5% in 1990, apparently.
And that's far outstripped by the current figure for renewables (42% in 2025) - so renewables have enabled locally-sourced production to reach more than double the share that was ever managed in the peat-burning days.
(And the comparison is actually even better than it seems at first glance, given that the 2025 figures are all-island and the peat figures would be 3 or 4 points lower if you included NI. A good chunk of the 23.2% imports can probably also be classed as renewable, given that GB had a 47% renewable mix)

Coal was almost 100% of China energy consumption only 15 years ago, with a bit of hydro. Today they are very aggressively shifting towards anything but coal, as you found in ChatGPT, to less than 60% of coal in the mix. For comparison, the US is almost at the same point today than 15 years ago, only significantly replaced coal with more gas.

Just to play Devil's advocate here, [approximately 600,000 people die each year from extreme heat, while 4.5 million die from extreme cold.](https://www.thelancet.com/journals/lanplh/article/PIIS2542-5...) Let's ignore the ratio for now, because there are second and third order consequences beyond extreme heat like famine to account for. 4.5 million people die each year because of inadequate access to cheaper energy. This is of course linear. Every time energy prices go up, so too do the number of people dying. That is the direct cost of the war on oil, coal, and natural gas, and there are many indirect costs (and lives) which go far beyond this. The intention of climate activists is to make fossil fuels much more expensive, meaning many more deaths.
Of course, maybe the goal here is worth killing 4.5+++ million people per year. There are no perfect solutions; only compromises. Maybe many more will die if we don't act. [The IPCC estimates that an additional 250,000 people per year, between 2030 and 2050, will die from the effects of climate change.](https://www.who.int/news-room/fact-sheets/detail/climate-cha...) That covers all modes of death, such as famine. For those in the room doing the math, many times more people will die today by making energy more expensive. Activists are asking us to sacrifice millions of lives per year today to save an estimated 250,000 lives per year decades from now.
For this reason, I no longer support making energy more expensive. I support environmental efforts to reduce pollution, but I can no longer justify the high cost of human life associated with taxes on energy. Instead, I really think activists should focus on making energy cheaper. This means working on solutions to make renewable energy and nuclear cheaper per unit of energy than fossil fuels. That's a path to saving lives which I think most people can get on board with.

I've personally spoken to people (who are otherwise quite environmentally aware) who suggest they'd never vote for the Green Party because they'd take their turf away. It's a tough sell.

People heating their homes can be very sigificant. In the UK ~15% of all its territorial GHGs come from heating with gas: actual CO2 from the home boiler flues.
CO2 from small amounts of rural home heating is probably not the big thing to be worried about, especially if local recent biomass, eg wood from forest management. But there are still nasties (PMs, biodiversity losses, etc) to be considered and that should be dealt with in due course.

If you use Renewable Energy Sources, it may happen there will be no wind or no sun. So you need some auxiliary source of energy. If you want it at hand, this must be something with fast cold start. So black/brown coal power plan will not help you, similarly nuclear. You need to burn either gas or "biomass", that is wood/turf, etc. Those power plants have about 1h cold start.
Hence, in order to have RES you need to emit CO2. Deal with this. The other option, and UK goes that way, is to purchase electricity when it is lacking, paying spot prices, that's why they have such a big electricity bills, economy is down, people get mad and vote psychos.
The solution is dead simple, as France example shows. Simply use nuclear power plants and does not bother with RES, as it does not make any sense now.
Maybe, when we have technology to store efficiently electricity at scale, we can start using RES. But we just do not have that.
The end result now is that electricity in Europe is the most expensive on the World, so all manufacturing is moved to Asia, who does not bother with climate that much, that's why, despite all Europe efforts, overall CO2 emission keeps growing.

Battery storage that works at grid-scale is a fairly recent technological innovation. It's good that humanity figured out this technological innovation, and demand for better battery technology from the smartphone and electric car revolutions had a lot to do with it. But battery storage is still expensive and relatively-new physical infrastructure that takes time and expense to deploy at scale, and it's still in the process of happening now.

Gas turbines can spin up significantly faster. However, the weather is quite predictable, so it is unlikely that this will be needed. Besides, battery storage is the perfect solution as an ultra-fast ramp-up holdover source until the turbines are at 100%.

Pumped storage hydro is extremely cheap and efficient and has been around for more than a century. LiFePo4 batteries are now cheap enough that they're a cost-competitive alternative. Flywheel storage plugs the inertia gap nicely.
The tech exists - it's mostly just a matter of political will. The economics already justify it. People are making considerable money by starting up BESSs (Battery Energy Storage Systems) and doing time arbitrage on energy.
cf. Iberia, who recently learned that effective storage and intertial pick-up is integral to a stable and efficient power network, and are now spending heavily on both.

It's a pipedream. Yes it's cheap and efficient, but it requires the geography and the will to destroy a local ecosystem.
BESS is what will ultimately win. It's pretty energy dense and it can be deployed on pretty much any junk land location. The only fight you'll have is with the neighbors who don't like it.
My power company, Idaho power, is deploying a 200MWh BESS on a slice of land they've owned for decades near one of their substations. The hardest part has been the permitting (which is now done).

This source also offers an option of $1 Trillion USD to do it with battery storage.
All of Europe. $1 Trillion USD. Oh, and that figure has already fallen by 1/3rd in reality and the article claims it should drop by half again.
And that seems to be assuming you only have wind power as input. The long lull periods that drive the high storage requirements are, as that article claims, caused by large high pressure air masses. High pressure systems like that often come with clear skies! Indeed, go look at weather history for that same 2015 period and you see that the skies were calm and clear, and precipitation was about half the "normal" amount for that time of year. While there is perfect correlation between a windless day and a night without sunlight, battery to get you through the night is trivial and solved far more cheaply than this article seems to understand. Enough battery to maintain 24 hour output for a solar farm is cheap enough to compete with fossil fuels. Long term, wind and solar do not correlate, so it's very rare to have long lulls in both at the same time.
So this article is leaving out important details and also is way more pessimistic than even it admits is true.
That also ignores that even in the "lulls", wind never seems to go to zero, so even in lulls, you can always just have more wind. Building 10x as much wind as you need is not as feasible as building 10x as much solar as you need though IMO.
Oh, and a very very very important fact: Renewable generation is almost entirely a one time cost, or one time every 30ish years on average. OPEX per kilowatt hour is dramatically lower than fossil fuels. In fact, today Europe imports 10 million barrels of crude oil a day, and at $100 a barrel (a number which will rise quite a bit in the coming months), Europe spends $1 Trillion every few years.
Europe's current energy spend is to buy an entire continent's worth of energy storage and just turn it into CO2 every few years. Every single day of crude oil import, Europe could instead pay for one of the Coire Glas model plants this article is doing the math with.
Storage is beyond feasible and will reduce energy costs.
Note: This article is about making wind energy constant over month long time scales, not about building enough storage to power Europe durably, so that explains some of it's misses, but also doesn't really explain much. The 2.1 TWh of storage it suggest would be enough to power all of Europe for 8 hours a day.

Nuclear plants provide base load and they are extremely fast at ramping up/lowering production. All modern nuclear plants are capable of changing power output at 3-5% of nameplate capacity per minute: https://www.oecd-nea.org/upload/docs/application/pdf/2021-12...

5% per minute is not extremely fast. Simple cycle gas turbine (peaker) plants routinely go 0 to 100% in less than 10 minutes. Nuclear plants can only hit 5% per minute in the 50 to 100% interval (per your own source).
And all of this is confused by the way the nuclear industry uses the term "load following". You'd think it means "changing the power output from moment to moment to match electricity demand" but for nuclear plants it means "changing from one pre-planned constant level to another pre-planned constant level, up to four times per day".[0] There are only three[1] sources of electricity that can be ramped freely enough to exactly match demand: hydro, simple-cycle gas turbines and batteries. All electrical supplies will need some of those three mixed in. Which is why France is still 10% hydro and 10% natural gas in their electricity supply.
0: Some of the most modern Russian plants can move to +-20% of their current target at 10% per minute, but "the number of such very fast
power variations is limited, and they are mainly reserved for emergency situations." per your source.
1: OK, there are some obsolete ways too, like diesel generators. At least obsolete at the scale of the electricity grid.

Imagine if you didn't omit the full quote/context:
--- start quote ---
Also, AES-2006 is capable of fast power modulations with ramps of up to 5% Pr per second (in the interval of ±10% Pr), or power drops of 20% Pr per minute in the interval of 50-100% of the rated power. However, the number of such very fast power variations is limited, and they are mainly reserved for emergency situations.

Oh look. What's limited is an actual emergency ramp up of 5% per second or power drops of 20% per minute.
Which is literally an emergency that is not needed in a power grid.
sehansen 1 hours ago [-]
Gas turbines do 16% of nameplate capacity per minute without catching a sweat. 5% per minute isn't particularly extreme.

Let me quote page 10 of your source "In brief, most of the modern light water nuclear reactors are capable (by design) to operate in a load following mode, i.e. to change their power level once or twice per day in the range of 100% to 50% (or even lower) of the rated power, with a ramp rate of up to 5% (or even more) of rated power per minute". Your own source defines "load following" as changing the targeted power level once or twice per day.
Again on page 14 (about how the French currently run their nuclear plants): "The nuclear power plants operating in the load following mode follow a variable load programme
with one or two power changes per period of 24 h". Weirdly enough this is contradicted by table 2.1 on page 20 where they do four changes per day.
---
> Oh look. What's limited is an actual emergency ramp up of 5% per second or power drops of 20% per minute.
If you look at table 2.4 on the same page it states that it (the Russian VVER-1200) can do the 5% per second/20% per minute emergency change 20 000 times over the lifetime of the reactor. The 10% per minute change can also only be done 20 000 times over the lifetime of the reactor. Table 2.2 on page 21 helpfully calculates that 15 000 cycles is once per day for 40 years, so the VVER-1200 only can do a bit more than one >5% change per day (outside of emergencies) assuming a similar 40 year lifespan. And that was the point of my footnote: that nuclear plants technically can go faster than 5% but not up and down on a minute-by-minute basis.

For the foreseeable future, building enough nuclear for peak capacity is exceedingly expensive.
> None of the power plants ever do a "fast cold start"
Somewhere in each grid you will have “black start” capacity contracts, dunno if nuclear can fills this role (or if grids exclude nukes for one reason or another).
Plenty of peaker plants built with the intention of running double digit hours per year and therefore the tradeoff supports being largely “off” in between those calls. Batteries might fill that gap.

The obvious counterexample is Chernobyl, where a big contributor was the fact that they were unable to scale it down & back up as desired. Yes, nuclear reactors can scale down rapidly - but you have to wait several hours until it can scale back up!
Besides, the linked paper only covers load-following in a traditional grid (swinging between 60% and 100% once a day) and barely touches on the economic effects. The situation is going to look drastically different for a renewables-first grid, where additional sources are needed for at most a few hours a day, for a few months per year.
> You don't shut down power plants. None of the power plants ever do a "fast cold start"

phil21 19 hours ago [-]
The answer is you don't scale nuclear up or down, it's a silly waste of time and effort to even think about it. The fuel costs are effectively a rounding error, so running at 100% 24x7 is the only way to ever think about how nuclear should operate.
If you are going to curtail, you curtail other sources including solar and wind.
Nuclear fits quite well for the baseload you need. It's more expensive, but if you are going to need X capacity 24x7 and build nuclear, you simply build enough to provide just that plus perhaps a few extra for redundancy when another one goes offline. Then use gas peakers for the "oh shit" days difference between what nuclear is providing and solar was expected to but could not.
I don't understand the fascination folks have about nuclear not being able to following the grid. They don't need to, since they only ever remotely make sense when operated 24x7 at 100%. If you always have 1TW of grid usage every night during your lowest usage period - build that much nuclear as your starting point and figure out the rest from there. Nuclear's share of the total mix should be a straight line on a graph outside of plant shutdowns for maintenance.
dalyons 7 hours ago [-]
That’s not the way the energy market works though. The cheapest sources (like daytime solar) will knock your expensive nuclear off the grid. Or force it to sell at significantly below operating cost, which is suicidal in the long term, since nukes need a guaranteed high price nearly 100% of the time to pencil out (pay back the capex).
Your argument only works in entirely state controlled systems, not in free energy markets of independent suppliers. Which is why nukes don’t get built.

The minimum requirements for the manoeuvrability capabilities of modern reactors are defined by the utilities requirements that are based on the requirements of the grid operators.

There's a declaration that a 915 MW power-plant was removed from the grid, and moved to emergency status only.
However, every other number in the piece is mentioned as some multiple of Wh's (GWh typically). That makes it very hard to tell what proportion of capacity was removed from the system as a proportion of the total generating capacity. I think the writer might have served us better with the use of some helpful percentage comparisons.
- Electricity demand in Ireland was 32.9 TWh in 2024, up 4.1% on 2023-levels
- Commercial services, which includes the ICT sub-sector, accounted for 41.2% of electricity demand.
- The residential sector accounted for 25.5% of electricity demand in 2024.
- Data centres accounted for 21.2% of all electricity demand in 2024.
- Data centres account for 88.2% of the increase observed in Ireland’s electricity demand since 2015.
If I've done my math correctly, Moneypoint generates about 8TWh, if operating continuously; which it's probably not. Can we say 6-7 TWh?
That is not an insubstantial portion of the total.

I am not sure it's a matter of how you frame the issue, to be honest, although I have seen this argument used quite a lot.
100% renewables is the exact opposite of "100% non-renewables" and that's including also oil, gas, etc. So "coal" is only a part of the 100% non renewables, but it seems your goal is to get rid of all the non renewables.
And here the question is: why would you want a single goal? Why 100% renewable?
What drives us should be: save where it makes sense, don't where it doesn't. Iterate every 10 years and recheck.
All these single radical goals are literally killing our economy and society. And I am not just talking about coal free or renewable.
Even the "let's tear down the windfarms" is dumb because it's radical and non sense.

Overlapping goals can coexist on varying time frames.
Setting aside nuclear (technically not "renewable", but also not carbon-based, and very energy dense) the goal is to stop releasing CO2 into the air from energy generation and return to pre-industrial levels.
This is because the surplus of CO2 generated so far has already caused clear and undeniable problems (not all of which are yet fully realized), and continued excess will only make things worse.

But the simple matter is thought that the economics of nuclear power simply are not delivering. They are expensive and slow to build, while at the same time wind (particularly off shore wind) and solar are getting cheaper and easier to build every year (or month even). Germany also stands out as a success story of nuclear phase-out, that by replacing these expensive to run nuclear power plant has offered the economic wiggle room to phase in renewables a lot faster then otherwise.

How much does power cost in Ireland?
landl0rd 21 hours ago [-]
Ireland is a net energy importer who imports electricity from Great Britain. She, in turn, often imports from nations including France, Holland, and Denmark, who use coal power.
As such, it's not really the whole story to call Ireland, "coal-free". It's the same as America outsourcing heavy manufacturing or chemicals to China and claiming environmental victory. It's true in a narrow construction of the concept; it does reduce the burden on one's own country. It is false in the sense of one's contribution to the global commons and externalizes those externalities previously more internalized. It is, in other words, a shell game. Ireland's dependence on imported energy continues to rise and the number continues to tick up on the books of other nations and down on hers, with her people paying the "guilt premium" associated with this accounting trick. They're not exactly dirty grids, but the fact remains, Ireland still relies to some extent on coal.
Also note that, though she is building OCGTs and fast CCGTs elsewhere, she converted Moneypoint not to gas but to heavy fuel oil. HFO is quite dirty stuff, only a dozen or so per cent cleaner than the coal it replaces per Ireland's own EIS. This is likely influenced by the fact that the plant was specced to burn some of the cleaner thermal coal on the market, largely from Glencore's Cerrejon mine, with pretty low sulfur and ash relative to others. So, the delta from relatively clean coal (excuse the expression) to some of the dirtiest oil; large boilers like that are likely burning No. 5 or 6, aka bunker B or C in marine. Not sure if you've ever seen (or smelled) this stuff but it's the next thing from tar.
Ireland could instead have chosen to pull in gas from the North Sea and reduced the emissions of Moneypoint by not twelve but fifty to sixty per cent with modern CCGTs. Even older, more readily-available OCGTs would give thirty to forty per cent. This is ~250mmcf, i.e. probably a 24" spur line. Though this likely necessitates a few hundred km of loop for the ring main to the west, it's less than a year's work with a competent American crew.
Instead, she chose a paltry twelve per cent a few years earlier; when the other gas peaker capacity is installed, cooling infra and existing thermal plant talent base while paying to reconstitute all those on the other side of the island.
None of this is to say Ireland's work on decarbonizing her grid isn't real, but "coal-free" rather tends to obscure the present state of things; it is generally understood to make a strong, binary truth claim that isn't subject to "mostly" and implies one is no longer dependent on coal. It therefore demands consideration of electricity's fungibility in a grid.

I'm not the enemy of this progress at all and think it's a good thing. Same goes for the Celtic Interconnecter, though.

Ireland imports less than 10% of it's electricity from the UK. The UK _already_ decommissioned it's coal-based eletricity production. The UK imports roughly 14% of it's electricity, and most of those imports are from nuclear and hydro-electric power.
Your entire comment is incredibly misleading.
landl0rd 20 hours ago [-]
No, it isn't. Power in a grid is fungible so grids operate based off consumption-based accounting. Britain continues to import at times from countries still burning coal. As such, Ireland is not free of coal dependence. It's really that simple. It is accurate for Ireland to say she no longer directly burns coal, no longer operates coal power, but the common understanding of "coal-free" is, "we are no longer directly dependent on coal for our lights to turn on." That simply isn't the case.
The way to think about this is, "If the grid had zero reserves and coal cut off, who could POSSIBLY go down?" You may figure this is constructed, but in a few days' dunkelflaute, Ireland needs her interconnects. Wind is then possibly low across much of Europe, meaning Holland and Germany ramp dispatchable capacity, including German lignite.

The point isn't about Ireland specifically so don't get hung up on that. It's a general shift away from coal.
1. There are coordination issues that have caused them to overestimate the need for such plants, which have been running at low capacity. There have also been perverse incentives to build plants that weren't needed, in order to placate the relevant stakeholders.
2. Battery storage (including pumped hydro) is being pursued aggressively, specifically (among other things) to address the reliability concerns that motivated the recent new coal plant construction. Government policy, furthermore, is clearly focused on "new energy", i.e. not fossil fuels.
3. Coal power generation in China has been level or declining for a little while now. Generation from new renewable plants is outstripping the overall increase in demand for power. There is a graph titled "New coal power has no predictive value for future coal power generation".
4. Historical, global evidence shows a persistent trend of capacity reduction lagging behind generation reduction. As should be expected. It takes effort (= money) to decommission a power plant, and an inactive (or less-active) one is a safety net. "In most cases, what ultimately stopped new coal power projects in those countries was not a formal ban, but the market reality.... In China, the same market signals are emerging: clean energy is now meeting all incremental demand and coal power generation has, as a result, started to decline."
5. As a share of total power generation, coal power in China has dropped substantially (from nearly 3/4 to scarcely half) over the last decade or so. In absolute terms, it is likely near or even past the peak.
6. The article concludes: "While China’s coal power construction boom looks, at first glance, like a resurgence,it currently appears more likely to be the final surge before a long downturn. The expansion has added friction and complexity to China’s energy transition, but it has not reversed it."
You asked:

They'd be better off with (and are building out) offshore and onshore wind. If you've ever been to the west coast of Ireland you'll know they've got almost unlimited wind energy. The country is targeting 5GW of capacity by 2030 and 37GW in the distant future[1].
If only they could harness the power of rain, Ireland would truly be an energy superpower.
> If only they could harness the power of rain, Ireland would truly be an energy superpower.
I know this is in jest, but that's basically "dam up some valley rivers and put a hydroelectric generator on the end", and unfortunately Ireland isn't so good for that. (It's not just the physical geology, it's also all the people living in the places you'd flood).
Hydro as a battery is easier and works in far more locations, but that's not harnessing the power *of rain*.
But yes, Ireland and the UK have an absolutely huge wind power resource available around them, IIRC enough to supply all of Europe if the grid connections were there to export it all.

You're mistaken.
Onshore wind in England was de-facto but not de-jure banned by the Tories in 2018, due to a footnote inserted in their National Planning Policy Framework. Labour removed this footnote in 2024, immediately after winning the election. [0]
Offshore wind was never affected, nor onshore wind in Scotland, Wales or Northern Ireland.
Thanks, I was quite mistaken indeed! I wonder how much onshore England then affected the big picture.
amiga386 18 hours ago [-]
Well, Tories would argue that you can't get the really big turbines onshore that you can offshore, so it doesn't really matter. Tiddly little turbines don't generate that much, and why spend lots of money on the planning process and fighting NIMBYs when you can generate it offshore?
However, it does matter, when looked at in whole with the need for capacity in the National Grid. A pile of turbines across SE England would have really helped, because a lot of the offshore wind and Scottish wind power has to be dumped, and gas generators fired up instead, due to lack of grid capacity to distribute that power across the country.
We should, of course, have completed upgrades to the grid by now, but they're late.
Not only has the UK not stopped building wind, they have over 30GW of installed wind capacity and sell electricity to Ireland for most of the year.
talideon 22 hours ago [-]
The 'sell electricity to Ireland' bit here is doing an awful lot of work. It's more complicated than that.
For those who don't know, Ireland operates an all-island grid, and EirGrid (the grid operator for the Republic) owns SONI (the grid operator for Northern Ireland). That means that 'UK' and 'Ireland' in this has a large Northern Ireland shaped lump of ambiguity that statement.
amiga386 18 hours ago [-]
It shouldn't be that complicated. The UK sells electricity to Ireland (and vice-versa?) in the same way that Belgium, France, the Netherlands, Denmark and Norway sell electricity to the UK, and vice-versa.
Don't tell me EirGrid's EWIC that comes onshore at Dublin and Greenlink at County Wexford are an "NI-shaped lump". They are sources of electricity for the whole island, when it's needed, just like the UK's interconnects with the continent.
Tories during 2015-2023 made construction of new onshore wind farms all but impossible (removed subsidies and made planning permissions very difficult). I would assume Labor could reverse these polices but haven't seen anything in news about this.
In 2000, coal was about 20% of the energy mix, gas another 20%, oil about 50%. Wind was 0%. In 2024 coal was about 2%, gas still 20%, oil still 50%, but wind grew to about 15%. It seems that wind actually replaced coal. It is not only logical, but good, that wind first replaced coal (dirtiest), and maybe from now on is will start to replace oil. Only after many decades, or maybe never, gas will be replaced.

energy vs electricity. oil is a much bigger part of the energy mix due to chemical manufacturing
crude oil and petroleum products (37.7%)
natural gas (20.4%)
renewable energy (19.5%)
solid fuels (10.6%)
nuclear energy (11.8%)
(2023 numbers)
So natural gas was just barely more than renewables in 2023, but according to the source below the line was crossed in 2025 and renewables now provide more than all fossil fuels put together:
For those following along at home, it appears enir is (edit: as well as using EU wide data, not Irish data..) including non-electricity generation, or non-grid, energy use. Grid stats available here https://www.seai.ie/data-and-insights/seai-statistics/electr...
Ireland has essentially no working oil power generation capacity these days (I think the only ones are a couple of small diesel units on islands, which are not even connected to the national grid). Moneypoint was replaced with some combo of wind, gas and imports.
(Moneypoint was actually built originally due to Ireland's over dependence at the time on oil for power generation; after the oil crisis, initially ESB attempted to build a nuclear plant (https://en.wikipedia.org/wiki/Carnsore_Point#Cancelled_nucle...), but it was such a political minefield that it was canceled, leading to Moneypoint.)

1. Emissions matter, not the particular fuel source they come from. Most places cannot meet 100% of their needs, or even 100% of their growth in needs, with renewables so they must use and even grow some fossil fuel sources.
India has vast coal reservers, and is the second largest producer in the world, whereas they aren't a major oil producer. Hence they use coal. Similar with China.
If the story was about some country shutting down their last natural gas plant instead of their last coal plant, no doubt someone would be pointing out that meanwhile the US is increasing natural gas production at a record pace.
In 2025 the US added 7 GW of natural gas electricity capacity, and India added 7 GW of coal. Natural gas generates about 1/2 the CO2 as coal, but India has over 4x the population, so the US added about twice as much new emissions per capita.
But we also need to consider how much renewables were added. That will be part of point #3.
2. India's emissions are 2 tons per year per capita, which is under 1/2 of the global average, which is about 1/3 the EU average, 1/5 of China, and 1/7 of the USA. Even if it takes them longer to get off fossil fuels than the other large countries they are likely to never come near the emissions levels per capita of those other countries.
3. They are actually making better progress at this than most others. 50% of electricity used in India is renewable, compared to 25% in the US, 40% in China, and 47% in the EU.
They are not just adding coal. They are adding wind and solar at record paces too. In 2025 they added around 7 GW of coal capacity last year, 38 GW of solar, and 6 GW of wind.
The US is doing the same, but with natural gas rather than coal. 7 GW of natural gas, 25 GW of solar, 13 GW of wind. About the same percentage of renewables (~90%) as India.
4. Yes, per capita is the correct measure, because the atmosphere is very efficient at distributing CO2 emitted anywhere to everywhere. A ton of CO2 has the same impact no matter where it is emitted. Unless you can make a good argument that some people have some sort of natural or divine right to a bigger share of whatever CO2 budget we decide Earth can afford, it has to be per capita.

Classic lie by omission. Or you're only reading right-wing media, in which case you can learn something and stop repeating this nonsense.
They build new coal plants as a backup, or to replace existing older plants. But they're very clearly not using them more than they already were. They burn coal because they have coal, just like the US burns gas because the fracking boom made gas cheap.
I think they'll follow China's lead soon. The economics are inevitable. Ember projects India will be at 42% renewable electricity by 2030, up from 10% today. This is obviously staggering renewables growth in a poor country.
Both India and China lack oil. Reducing fossil fuel usage is a national security issue for them. They're also poorer. As solar and wind become the cheapest sources of electricity, thanks mostly to China, they're going to rapidly transition. No dumb political games.

Never used coal power:
Phased out: Phase-out planned:Definitely wrong - Malta has used coal power for example. See for example:
https://www.ebsco.com/research-starters/power-and-energy/mal...
"In 1979, a second oil crisis, this time due to the Iranian Revolution, again brought into question Malta’s energy policy and made the government seek alternatives. Between 1982 and 1987, four stream turbines were installed at the Marsa Power Station. This strategy could have worked if the environmental and human health impacts of the coal used at the power station had not caused the local population to protest. In 1987, construction of a new power plant, at Delimara, started; the plant was commissioned in 1994. In the meantime, the Marsa Power Station continued to be improved, with new turbines added to eliminate the use of coal. On January 12, 1995, Malta became independent of coal but consequently became fully dependent on oil."
I should also note it is primarily a gas plant, fuelled by extremely cheap (nearly free) gas subsidised by Russia. It only falls back to coal when supply is disrupted, which happened when Ukraine stopped transiting Russian gas on its territory.
It is technically still considered Moldova by everyone else so it's not differentiated in documents from the EU and the likes.
For most practical purposes, Swedish electricity generation has been basically fossile free since the 1980's.
Specifically in district heating, 87% of the forestry-sourced fuel is unrefined wood products. Almost half of it is just bark, branches and treetops. Of all the biomass in an average mature tree logged in Sweden, 43% ends up as pulpwood, 43% as saw timber, 8% gets burned for fuel and the remaining 6% is treetops and branches which also tend to end up burned for fuel.
There is definitely a lot of debate in Sweden about sustainable forestry practices, though. The industry really wants to clearcut everything for convenience, but it's really bad for biodiversity and the general public hates it.
Source: the report Hållbarare biobränsle i fjärrvärmesektorn, Energiforsk 2023; specifically the charts on pages 14 and 15. Link: https://energiforsk.se/media/33316/2023-979-ha-llbarare-biob...
Addendum: I believe there's also been some studies and experiments involving importing olive pits from the Mediterranean olive oil industry for burning in district heating plants, but I don't think it's been done at scale.
It makes more sense to leave trees in the ground than burning them to generate energy
I think "practical purposes" should include the fact that thanks to also shutting down a bunch of nuclear, Sweden regularly imports German/Polish coal power.
Sweden claiming fossile free is only technically true. Practically there's a mountain of greenwashing.
So no, I would not say what you just said. I find that greenwashing dishonest.
By being anti nuclear, the green parties around the world have caused more radiation[1] and climate changing co2 than any other movement in history.
[1] An oft cited statistic is that coal causes more deaths every single year from radiation (excluding accidents) than nuclear has has caused in its entire history INCLUDING accidents.
In 2025, the net export was about 33 TWh. Gross import from Germany, Poland and Lithuania, including transit to other countries, was 1 TWh. So, imported power from countries with coal power plants was less than 1% of total consumption, and the amount of fossil free power exported was more than 30 times greater than the amount of (potentially) fossil power imported. 2% fossil energy in the mix is to me not really significant, and especially not considering how much fossil free power is exported.

Well, sure is good the environmentalists shut down the German nuclear plants!
Does Russia benefit and probably fund it? Sure.
But DACH environmentalism grew from antinuclear protests, not the other way around, and thus will boycott nuclear even when it goes against their modern stated goals.
It would be good if we could modernize our grid to support easier exchange of power from north to south and vise versa.
Shutting down the nukes is inversely proportional to homeopathy in Germany. That says it all

It seems they consider only coal use in the 21st century in mainland Europe + UK (i.e. not Greenland, Iceland, Svalbard, etc.).
Reference? This seems to be false. Coal is still on decline, while solar is what's ramping up [1][2]

Is there something I'm missing here?
The article you linked is mostly about a model of 2026 and 2027 and sure, in the model coal goes away but that's not a fact about coal it's just a model.
"Ramping up" means planned to increase.
Feel free to provide a reference that supports that it's "ramping up". I, and parent, couldn't find one. This is a super boring factual thing that I was curious about, where opinion has no place or purpose.
No it doesn't. It means increasing.
Okay, but you're celebrating make-believe virtues. Iceland is also not destroying its tropical coral reefs. That sounds nice...but it has none. Nor any sort of tradition or incentive to try doing that.
The US coal thing is all about widespread memories (and myths) of sustained good economic times, in large areas of the country which now feel destitute. Millions of voters feeling that they have no future. If not that the elites want them to hurry up and die.
To paraphrase Munger - if you want different outcomes there, then you need to change the incentives.
Being coal-free is possible. Being fossil-fuel free is harder. Most of Irish energy comes from Natural Gas and Oil - the former is what supplanted Coal, not Wind.
In 2026, coal now provides 0% of the mix while wind provides 30% or more. Peat burning has also been fully phased out while oil (Tarbert) is in the process of being shut down while Moneypoint has been converted to oil but only participates in the capacity market - i.e. as an emergency/backup source - and so barely registers in the mix.
And even if coal was supplanted one-for-one with NG, it would still be a net win - by halving the CO2 intensity of generation as well as being far more flexible, scalable and much cheaper to deploy.
There is absolutely no good reason to burn coal for electricity or heat in this day and age. If we had sane global leadership, every coal power plant left would be treated as a WMD and be bombed harder than that Iranian fuel depot.
Calling something a religion is a lazy and disingenuous way to dismiss it. The effects of airborne and waterborne pollution on human health has been the focus of scientific investigation for centuries at least. Ecosystem destruction is not "a religious belief" - it's something which has been measured, carefully recorded and studied using scientific methods.
> at 1/1000th the cost of re-wiring our entire energy system around renewables
This is alarmist hyperbole. Renewables now account for about 35% of the global electricity generation mix. There are countless examples of countries that run grids where renewables account for more than 80% of the electricity mix. Even if you just consider wind and solar, many countries are approaching 50% penetration in the space of 20 or 25 years without "re-wiring their entire their entire energy systems".
Yes NG generation is the only fossil tech still standing in terms of being able to compete at any level with modern generation tech but it is being squeezed. Batteries surpassed NG in terms of economics for peaking sometime around 2020/2021 - which is reflected by the share of new capacity investment since then.
> industrializing 3B+ people using windmills
A windmill is a device used to mill materials that happens to be powered by wind, like a watermill, or a pepper mill or a paper/wood/etc mill. I'm not sure what that has to do with electricity generation.

They have more coal power plants planned and your data hickup worked out during recensions and covid.
- China is also decommissioning older plants.
- These new coal plants aren't running 24x7
- Peak coal usage is likely to be very soon in China (this year even according to some); after that coal usage flatten and start declining; all the way to a planned net zero in the 2060s.
The newer plants are designed to be more efficient, more flexible, and less polluting than the older ones. They are better at starting/stopping quickly/cheaply. Older coal plants used big boilers that had to heat up to build up steam before being able to generate power. This makes stopping and starting a plant slow and expensive. Because they consume a lot of fuel just to get the plant to the stage where it can actually generate power. The more often plants have to be stopped and started, the more wasteful this is. With the newer plants this is less costly and faster.
This makes them more suitable to be used in a non base load operational model where they can be spun up/down on a need to have basis. This is essential in a power grid that is dominated by the hundreds of GW of solar, wind, and battery.
This means that global consumption will decline too which coincides with both factories and power plants shutting down
https://www.eia.gov/international/analysis/country/chn
Their existing grid uses coal because they have coal, just like the US uses gas because it has gas. And obviously as old coal plants are retired they're going to build new ones. They don't use the new plants for additional capacity. As they add more solar and storage, which they're building a lot of, they're going to absolutely crush the coal burning too. It's literally a national security issue for them.
China is more electrified than most Western nations and getting more so faster than Europe or the US:
https://ourworldindata.org/grapher/electricity-as-a-share-of...
Source? Does that take into account full life cycle (including manufacturing)?
This even compares cars built in an unrealistic 100% coal grid, and fuelled on 100% coal grid. Driving 14k miles a year for 10 years a Tesla Model 3 built under those extreme conditions beats a gas Fiat 500
But look at the data. They are building clean energy solutions at a faster rate than any other country on the planet - by a huge margin. Scaling clean energy solutions is what we need, and it has to be done alongside the gradual phase-out of coal and gas.
The population of China has been decreasing since 2022.

Setting that aside, China has also dramatically pushed the electrification of their transportation sector like no one else. Considering BEVs and other electric modes of transport require less primary energy than fossil fuel equivalents, this checks out.
And if your minimum unit size is 1GW then you lose the flexibility to roll out the tech incrementally - the average modern coal plant requires 3 to 5 weeks per year for scheduled downtime for maintenance - so your first 1GW coal plant requires a bunch of other generation sources to cover demand during these periods.
Solar and batteries are the obvious solution for rural electrification: scaleable, cheaper/simpler to deploy - no large scale civil engineering involved, trivial to "operate", effective without the support of big transmission systems and it's possible to buy everything off-the-shelf.
Coal requires transport and extraction which are both pretty expensive processes.
In my home town of ~300 people, there was just a couple of houses which used coal for heating. That's because sourcing and transporting coal was quiet expensive.
Electric heating was much more common. Even the old expensive baseboard resistive heaters.
When we talk about extreme rural areas, what you end up finding is solar and batteries end up being the most preferred energy sources. This has been true for decades. That higher upfront cost is offset by not having to transport fuel.
It's why you'll find a lot of cabins in pretty remote locations are ultimately solar powered. This is long before the precipitous price drop of solar.
Last I checked mining and transporting coal required quite a lot of heavy industry equipment to do even vaguely economically.
If coal was cheaper and easier than other sources of energy, then the US would be building more coal power plants. But even with the Trump administration placing its weighty thumb on the scale to try and “save coal”. Coal plants are still being shutdown due to simple economics.
If existing plants can compete with renewables, to hard to understand how adding the cost of building new plants is going to change that.
The article also notes that solar and wind capacity grew significantly faster than actual generation, suggesting "unreported curtailment" (where clean energy is wasted because the grid can’t handle it). If curtailment is rising, it means the "clean energy boom" is hitting a hard infrastructure ceiling. The research assumes that if grid issues are resolved, emissions will fall further. However, if the grid cannot integrate this power fast enough, the 290GW of coal power currently under construction will be called upon to fill the gap, potentially leading to a sharp emissions rebound in 2026–2027.
Further, a major driver of the emissions drop is the 7% decline in cement and 3% decline in steel emissions, linked to the ongoing real estate slump. This is a cyclical economic event, not necessarily a green technological victory. If the Chinese government pivots to a new stimulus package (e.g. massive "New Infrastructure" or high-tech manufacturing zones) to save GDP growth, the demand for steel and cement could surge again. The research treats the real estate decline as a permanent plateau, but China’s history of state-led investment suggests that industrial emissions can be turned back on by policy shifts.
Further, the analysis focuses almost exclusively on CO2. China is the world's largest emitter of methane, primarily from coal mine leakages. Even if CO2 emissions from burning coal are flat, continued coal production to feed the coal-to-chemical industry (which grew 12% in this report) results in significant methane venting. If you account for the Global Warming Potential (GWP) of methane, the total greenhouse gas trend might look much less optimistic than the CO2-only trend.
Further, the report credits a 3% increase in hydropower for helping suppress coal. Hydropower in China is extremely volatile and dictated by weather patterns (e.g. the 2022–2023 droughts). A single dry year in the Sichuan or Yunnan provinces can force a massive, immediate pivot back to coal-fired power to prevent blackouts. The 21-month trend may be as much a result of favorable rainfall as it is of solar panels, making it fragile and reversible.
Further, the report highlights a 12% growth in emissions from the chemical industry, driven by coal-to-liquids and coal-to-gas projects. This suggests that China is not decarbonizing its economy so much as re-carbonizing its industrial feedstocks. As China seeks energy security to reduce its reliance on imported oil and gas, it is building a massive coal-based chemical infrastructure. These emissions are harder to abate than power sector emissions and could eventually offset the gains made by wind and solar.
Ultimately, China is still the largest polluter (in every sense of the word) by a large margin. It's nice to see them taking steps to curb this, but we should all remember that any environmental benefits are purely coincidental to their goals of energy independence. We should expect them to rely on a diverse mix of sources - including the 8+ "mega" coal power plants coming online every month.
To be fair, there's a large (~300mn) agricultural population in China who don't use developed country levels of energy. Nonetheless, this is still good.
I understand China has about twice the inhabitant of USA+EU but the same consumption based CO2, am I wrong?
Second, a lot of the EU stuff is already dead and only continues to exist through inertia. The median German cars and machine tools are worse than the median Chinese and they cost far more.
Third, those numbers often reflect the nebulous concept of "value added." Let's take the case of a refrigerator. Chinese company manufactures every technical part of the refrigerator and ships it to their EU business partner for €100. EU partner assembles it, fills it with foam, and sells it for €600. Most of the "value added" was in the EU! Win for the EU! Go EU manufacturing! The concept of "value added" is the basis for the entire EU VAT system and much of its economic indicators and incentives, while in the US it is almost never mentioned. This is also the source of the most hilarious comparisons (Greek manufacturing superior to the US per capita? χαχαχα)
If you want to cut through the bullshit, you have to look at actual things made. Among the US/CN/EU, who leads: Solar panels (CN), cutting edge chips (US), chipmaking equipment (EU), jet engines (US), aircraft (US), space launch vehicles (US), fighter jets (US), batteries (CN), nuclear reactors (CN), submarines (US), advanced missiles (US), cars (CN), CNC machines (CN), machine tools (CN), precision bearings and linear motion systems (CN), cutting edge medical equipment (US), gas turbines (US/EU), high voltage grid equipment (CN), telecom equipment (CN), construction equipment (US), ships (CN), advanced optics (EU), electric motors (CN), steel (CN), aluminum (CN), oil (US), cutting edge pharma (US), industrial robots (CN), wind turbines (CN), trains (CN), agricultural machinery (US/EU), drones (CN), smartphones (CN.) From that list, China leads eighteen, the US leads eleven, the EU leads two, and the EU and US are tied for two. And China is closing in fast on chipmaking. When China takes that crown, what will the EU have left?

Apso not sure if you are including coal mining, and all of the deaths and negative health outcomes as a result of the industry
Have you ever seen the common medical advice that pregnant women should avoid eating more than a few servings of seafood every week, and avoid certain kinds entirely, because they’re all contaminated with mercury? A huge portion of that mercury comes from burning coal. How’s that for an exclusion zone?
Also there is a single case that happened from a non-western design. When looking at western countries like France, it shows how incredibly safe the whole industry is end to end.
It's our unique freedom-themed nonsense, not the Soviet dictatorial-nonsense, which means we have radiation standards strict enough that it's not possible to convert a coal plant into a nuclear plant without first performing a nuclear decontamination process due to all the radioisotopes in the coal.
That said, perhaps that's actually a problem with the coal plants rather than nuclear standards: https://www.nature.com/articles/s41467-026-69285-4
> When looking at western countries like France, it shows how incredibly safe the whole industry is end to end.
Relative to coal, absolutely. But don't assume western countries are immune to propaganda on these things, nuclear reactors are there for the spicy atoms, not the price tag or public safety.
That is, nuclear power plants only kill people by radioactivity in the case of an accident. Coal power plants do it in normal operation. As well as coal dust having a PM2.5 dust problem which kills people.
Make it about nuclear vs coal because people say coal is better than nuclear because it's not scary radiation, and it actually is.
> "Both are bad"
Nuclear generates more power from a Kg of fuel, with less CO2 pollution and fewer deaths. It's not bad, but even if it was bad it's not "both sides", it's much less bad.
[yes coal disasters also kill hundreds of people: https://en.wikipedia.org/wiki/Aberfan_disaster ]
I don’t think nuclear is the answer to things. But replacing every ounce of coal used for fuel with nuclear would still be a win.
I think that the last time I checked, when you take into factor the CO2 emissions and everything, Nuclear is the best source of Energy.
> I don’t think nuclear is the answer to things
I think that I am interested in seeing thorium based reactors or development with that too. That being said, Nuclear feels like the answer to me.
Feel free to correct me if you think I am wrong but I don't think that there is any better form of energy source than nuclear when you factor in everything.
No economy on the planet needs 24/7 peak power production. The times humans work correspond nicely with the times the sun is out.
Yes I agree but their extraction at scale is still very C02 Expensive.
> No economy on the planet needs 24/7 peak power production. The times humans work correspond nicely with the times the sun is out.
With Nuclear energy, let's face it. If you have a nuclear plant running, the input is just some uranium which we have plenty of. Thereotically we have no problem with running at peak power production.
You are also forgetting that Sun can be blocked during times of rains and Wind is unpredictable as well.
If you can work with solar panels only that's really really great. Unfortunately that's not how the world works or how I see it function :(
You are forgetting that markets operate after work and the late night culture and so many other things. You need lights at energy and quite a decent bit. You are also forgetting that if we ever get Electric vehicles then we would need energy during late night as well.
A lot of energy in general is still needed during nights and would we be still burning coal for that?
With all of this, I am not sure why you'd not like Nuclear?
We already have wires that cross continents to smooth out supply variations. It's exceedingly rare you get no sun and no wind over entire continents for an extended period.
> You are forgetting that markets operate after work and the late night culture and so many other things.
I'm not forgetting it, they just use less power.
You can see this easily in charts of supply/demand throughout the day: https://www.caiso.com/todays-outlook#section-net-demand-tren...
> A lot of energy in general is still needed during nights and would we be still burning coal for that?
Again, batteries.
I can be wrong but you would probably lose tons of efficiency even within High Voltage DC lines if everyday late night we take energy from different countries. Also this is getting outside of topic of discussion for me because one of the reasons we want Nuclear or Green energy in general is also the environmental plus the sovereign plus the long term affordability plans.
Another point from your first comment but if we run peak production in nuclear say in a country A, then the country A can also give power to Country B at late night similar to what you are proposed for solars.
> Again, batteries.
Once again, within my first comment I raise issue of battery. You mention a comment and I respond and then we get to batteries again.
I have no problem with solar at all without batteries but batteries really flip the equation in terms of environmental concerns.
My question is plain and simple, Why not Nuclear? I understand, I am not against Solar. Although environmentally, I feel like battery is a valid concern.
I am just saying that long term, Nuclear seems to be the better/best option. Why not Nuclear? That is a question which it seems that you may not have answered and that's a discussion worth having as well In my opinion too.
We can agree on this, correct?
Nuclear power is expensive, enough that “what about night” is solve by building extra solar and batteries. Also, renewables wreck the economics of base load power that needs to run all the time to pay back loan, but can’t compete with solar during the day.
Yes. Because they're the answer here.
> Also this is getting outside of topic of discussion for me because one of the reasons we want Nuclear or Green energy in general is also the environmental plus the sovereign plus the long term affordability plans.
Good luck with nuclear sovereignty, if that's your concern. How many uranium mines are in the UK?
> Why not Nuclear?
/me gestures at the last 50 years of historical evidence
"Why not try nuclear" is like "why not try communism?" for physics nerds. We have tried it.
I can't speak about UK but considering how cheap Uranium is, can UK not do cost analysis. Uranium is abundant material compared to Oil/Coal.
> /me gestures at the last 50 years of historical evidence
> "Why not try nuclear" is like "why not try communism?" for physics nerds. We have tried it.
Maybe, but I think that, I can speak about the problem within US which I can better explain but US had nuclear fearmongering attempts and Senators passed laws which increased regulations on it to the point that some regulations contradict past regulations.
Nuclear power plants being built on loan in such a flimsy regulatory market was what lead to the downfall essentially within US
Nuclear fearmongering and lobbying efforts from Oil Industry as they are one of the most strong opposers of nuclear energy[0]
Once again, how do I explain this but nuclear produces 3.2x less carbon emissions than Solar[1]
We are able to build hydropower plants, we are able to launch spaceships into moon and outer space. It's definitely possible to build nuclear if lobbying effort decreases.
I'd say that its our dependence on Oil and Coal which have been the problem. I have nothing against solar and that is something that I am saying from the start. At some point we should look towards transition towards nuclear as well. To give up on that would simply not be ideal.

Wait until you hear how cheap and abundant sunlight and wind are!
Economically useful uranium deposits are only proven in a handful of countries.
> We are able to build hydropower plants, we are able to launch spaceships into moon and outer space. It's definitely possible to build nuclear if lobbying effort decreases.
This is the "well we haven't tried real communism" argument again.
I was going to ask you 3-4 questions but then I searched them upon myself and I do think that the results are more (positive?) than I thought.
Solar could feed world's energy needs by 0.3% and I think that Excess Solar could be used for green Hydrogen etc. too when needed for burstable energy source and smart grids in general to fix the ramp-up/ramp-down problem
I think one of the only things that I was sort of worried about mainly was the fact that Batteries produce lots of Co2 emissions and harm to the planet when mined but it seems that they have lifespan of about 10 years and can be carbon negative 3-4 years.
I don't know, I go through waves of doubt over Solar. I might need to learn more about Solar because I feel like I can just agree to whatever side I hear the recent data's from. Lies, Damned Lies and Statistics it seems.
But I feel like although solar is right direction too, we probably need smarter grids and just improvements within grid infrastructure in general too. Another point about Solar could be that there can be a more personal adoption of it whereas I can't build my own nuclear power plant so I do agree with you.
I'd still say that there is a lot of greenwashing in the Climate Change community to treat wood-chips and trees as fuel source and all the problems that stem from that with timber industry.
So although there are short-comings in Solar given its intermittent nature. I do agree that unless Govt.s create nuclear, it could be a good bet for personal actions/ even Govt.s to diversify at the very least from Oil.
I still think that though there is something wrong where People are wrongfully worried about nuclear. India for example had 3% of its energy coming from Nuclear and I looked at wiki and we planned even more but anti nuclear protests started happening after Fukushima Disaster :(
I am still really interested about Thorium Reactors and the race towards building it though. They are mostly disaster-free and Indian in particular has quite a large reserve of Thorium (25% of the world supply). The govt. is working on making 100GW to raise thorium's ratio in energy to almost ~10% estimate from 3% till 2047 which would still be impressive given that total energy would skyrocket as well till then.
India has true chances of being Energy Independent long term if it focuses on nuclear and Solar both rather than focusing on Solar given any advancement in Thorium reactor will be huge for us. For reference Coal : Thorium power ratio for same mass is 1:3.5 Million and its even more efficient than Uranium.
Also Thorium cannot be used for Nuclear Bombs in the sense of a fission unless you drop it at someone complete point blank but at that point its worthless compared to missiles so we can genuinely share this technology all across the world.
Thorium Reactors long term feel the future to me. So maybe I am too bullish on Thorium.
Solar is nice but atleast personally, Investments in Thorium Reactors could make India Energy Independent given 25% of the supply. We also recently found a huge jackpot in lithium and other minerals in Kashmir recently so I suppose long term India can be sovereign in manufacturing batteries for Solar production as well.
There is such a massive possibility in nuclear especially more so for India and general consensus also being within Scientific community that nuclear energy is cleanest forms of energy. The Combination means that, I'd want my govt. to take some risks in nuclear research/projects given how big the reward can be and that's also why I vocally support Nuclear. Much more than Solar. But I'd say that any govt. has their own risk profile and maybe Solar can be boring but works technology for Energy Independence so I just hope that Solar & Thorium both show some good numbers long term as well. So it isn't as if I am anti Solar as much as I am very pro nuclear energy long term.
Relevant Video: Thorium Reactors: Why is this Technology Quite So Exciting: https://www.youtube.com/watch?v=jSFo_92cJ-U
And off course societal (and geopolitical) acceptance issues.
Right. One thing I've rarely heard emphasized is that, while nuclear power is not at all the same as nuclear weapons, it's still infrastructure that can be repurposed from one to the other. A world where nuclear is the predominant base load power source is a world where nuclear weapons are more accessible due to the proliferation of sibling technologies.
I don’t understand what you mean by “no learning curve”. Do you mean that the learning curve is particularly steep for plant operators?
And people are (mostly irrationally) terrified of it, which matters in democracies.
Is there any particular reason why you think Nuclear is bad in all honesty as its worth having a discussion here? Why do you feel Nuclear Energy is a hazard?
I understand if you feel Chernobyl or any event makes it sound dangerous but rather, Please take a look at this data on the number of death rates per unit of electricity production[0]
Oil is roughly 615x more deadly than nuclear. Nuclear, Solar and Wind (the renewables) are all less deadly and are 0.03,0.02 and 0.04 respectively and nuclear is a reliable source of energy source which can be used in actual generation.
Nuclear is very much a green energy. I'd like to hear your opinion about it.
[0]: https://ourworldindata.org/grapher/death-rates-from-energy-p...
Even within Chernobyl Disaster, it was a series of mistakes which led to the full scale disaster IIRC so it isn't as if a single mistake
Also Thorium based Nuclear Reactors wouldn't have this issue from what I understand as in the idea of explosions or anything,
> Nuclear plants are great if they actually happen to get built
I get this part but shouldn't this mean that people should be more vocal about support for Nuclear. We are vocal about support for Solar, might as well be vocal about support for Nuclear and Solar both too?
When multiple systems are combined the percentage of things filtered out is:
Pollutant Typical removal Dust / particulate matter 99–99.9%+ Sulfur dioxide (SO₂) 90–98% Nitrogen oxides (NOx) 70–90% Mercury 80–95%
I will happily trade 10 unit of energy for just a single unit of energy, assuming I get to decide when I give the 10 units and when I can demand the 1 unit. A lot of profit in the European energy market can be made by such a "bad" deal.
The date when a country energy grid is free from fossil fuels, like coal, is when the grid has no longer any demand during the year for producing or importing energy produced by fossil fuels.
But: EU is the only effective player in the world that drives energy policy outside its borders, by being a massive market with regulatory power regarding its imports.
If you look at three figures: energy use per capita, emissions per capita, and GDP per unit of energy/emissions, and include imported consumption, the EU's are all trending in a positive direction for many years now.
So stating the EU has de-industralized and its progress on shutting down coal is therefore 'fake' and misleading because it imports its industrial consumption from other countries to which it has simply offloaded its emissions, isn't true.
Noah also tries to refute the perception that manufacturing is in decline in the US, but he doesn't adjust per-capita and doesn't account for the obvious fact that major US exports are looking more and more like raw materials and less like finished goods, while imports are the other way around. Aircraft and ICs used to compete for top spot on the US export list. Since 2008 it's petroleum and oil.
If major advanced economies are able to move their entire grid away from coal, it means the entire grid globally can move from coal.
"Ah", the critics say, "but manufacturing is so much more complex!"
Really? These are not countries without manufacturing. They have data centres stacked with the latest generation of Nvidia chips, electric rail, major capital cities, populations of millions...
... and of course, China agrees and is trying to move towards decarbonisation of their grid.
Yes, it'll take time, but it'll take even longer if you never start.
I mean, the UK proudly trumpets that they're coal-free, while entertaining a new coking coal mine.
Electric power—469.9 MMst—91.7%
Industrial total—41.9 MMst—8.2%
Commercial—0.8 MMst—0.2%Getting down to 6% of our current coal use would be amazing. So much lung cancer and asthma would be prevented.
[1] https://www.eia.gov/energyexplained/coal/use-of-coal.php
Even if some of that replacement is with gas it still helps. Gas emits about half the carbon per kWh.
This is generally overstated. Emissions imported or exported via trade are significantly smaller than domestic emissions for almost every country. In the EU vs China case, accounting for imported/exported emissions basically changes which of the two is doing better, but emission levels are pretty close to begin with (US is already doing significantly worse than China either way).
For China, we are talking about ~1 ton/person/year from trade (in favor of China), while local emissions are at ~8 tons/person/year [1].
You make a valid point, but looking at the actual numbers it turns out that this makes (surprisingly) little difference.
[1]: https://ourworldindata.org/grapher/imported-or-exported-co-e...
The whole conversation about clean energy is polluted by the complete misunderstanding of the general population of how energy demands are balanced. Saying you're replacing coal and gas with wind is just nonsense. It's one solution to a bigger problem. The big problem is how to balance your grid across peaks and troughs and that requires a diverse set of clean energy solutions, with wind being one small part of it.
To anyone praising these stupid, politically incentivised initiatives - congratulations to us on making the poor and middle-classes poorer.
But it's all good - we're saving the world I guess. The poor folks can sort themselves out.
Lower population density on a grid without good connections to neighbours.
Previous underinvestment in network infrastructure.
Gas price rises combined with Ireland having less renewables that the EU average (middle of the pack for electricity, 3rd from bottom on total energy).
Maybe saving the world a bit harder would have helped keep prices down. It's certain that building more renewables now is the likeliest path to cheaper electricity.
A report supporting those claims: https://www.nerinstitute.net/sites/default/files/research/89...
Wrong comparison. Most of Europe has way too high electricity prices.
It seems logical that ending the use of existing coal energy infrastructure puts upward pressure on prices. Coal is cheap, abundant, energy dense.
Yes, burning coal causes lots of problems and I support ending it's use, but this is besides the point.
Only if you externalize environmental costs. The point is that coal is actually really expensive. The only real argument is how fast the implicit subsidy on these externalized costs should be removed. The world has had decades to slowly remove these subsidies and failed to do so. The impacts caused by these externalized factors are starting to stack up and so should the prices.
Coal is neither cheap nor abundant in Ireland.

Also you mention albino and I can't find what that would mean in this context. At first I assumed you meant albedo but that doesn't seem to contextually match either. So I might just be misunderstanding your post.
For one the EROEI isn't 4 for renewables under ideal conditions, it differs wildly depending on the type and location and installation. It's true that for solar in Ireland (which are NOT ideal conditions) its on the low end, though still about twice as much as 4, and it's certainly not the case for wind which can have them as high as 20.
Second, I've got no clue what 'albino' is. Do you mean albedo? In that case, it's completely irrelevant for wind power. Ireland produces 20x more wind than solar, the latter is completely irrelevant in Ireland.
For solar albedo is relevant, but only if you have bifacial panels, which are still the minority.
In Spain albedo is relatively low but it has some of the highest direct sunshine hours in Europe. Albedo is high in places like the Nordics, which have fewer sunshine hours. In other words, EV is brilliant in Spain due to the abundant sun, yet surprisingly is still viable in a place like Norway precisely because of relatively high albedo, not in spite of it. This is why EROEI for solar in Spain can get up to 20. The idea that you get as much power as it took to make (EROEI of 1) is so wrong, and so obviously wrong, that it seems like you just don't have any idea what you're talking about.
https://www.eirgrid.ie/news/new-record-wind-energy-all-islan...
For actual generation over a longer time period, in February 2026, 48% of energy used was generated from renewable sources, of which the vast majority (41% of energy use) was wind:
https://www.eirgrid.ie/news/almost-50-electricity-came-renew...
(The previous February was slightly better with 54% renewable and 48% wind)
https://www.eirgrid.ie/news/renewables-powered-over-half-ele...
I do see in the political goals for Ireland that they, like Germany and many other countries in EU, are relying on the idea to turn wind into green hydrogen once they hit that 100% during optimal weather. Peoples faith in that strategy has gone down significant in the last 5-10 years.
I guess we need a new planet when we're done filling it with junk and have depleted all the rain forest etc
If you want solar PV to help with AGW, they must be sited somewhere with an solar albino > .25. That's about Barcelona in Europe and SF in the US. If you put solar PV somewhere with less sun, you are actually making AGW worse.
> The EROEI of renewables is 4
Saying "renewables" have an EROEI of 4 is disingenuous at best. "Renewables" isn't one technology, it covers everything from wind to solar to geothermal to hydro. That 4 figure comes from worst-case transitional modelling of buffered wind specifically, and even then it's a temporary system-wide dip, not a measurement of what these technologies actually deliver[1]. Wind and solar individually come in at >=10:1 and rising as the tech matures[2]. Geothermal actually is in the hundreds, but that obviously isn't globally applicable. Lumping all of that together and slapping a "4" on it is either ignorant or deliberately misleading.
And the "hundreds" figure for fossil fuels is pure fantasy. Conventional oil sits at roughly 18-43:1, and US fossil fuel discovery EROI has cratered from ~1000:1 in 1919 to about 5:1 in the 2010s[3]. A paper in Nature Energy last year took it further and showed that when you measure EROI at the useful energy stage - accounting for all the waste heat from combustion - fossil fuels drop to about 3.5:1, while wind and solar beat the equivalent threshold even with intermittency factored in[4]. So "the laws of physics" are actually making a pretty strong case for renewables here.
> If you want solar PV to help with AGW, they must be sited somewhere with an solar albino > .25
I think you mean albedo. And that claim has been tested[5], a satellite study of 352 solar sites found the actual albedo reduction was much smaller than what's typically assumed, and the warming effect was offset by avoided emissions within roughly a year at most sites. A separate study of 116 solar farms found a net cooling effect on land surface temperature[6]. The idea that solar north of Barcelona is "making AGW worse" just doesn't survive contact with the data.
> ...but they don't care about your politics (or mine)
What a deeply unserious tone to take in a discussion like this. Where in my comment did I mention politics of any kind? Is any mention of renewables in a positive light political to you, or is it where I questioned whether the same scrutiny gets applied to fossil fuels? Because that's not politics, that is just reality which you seem to care so much about.
Newsflash, you don't need to be a leftist (which is what I assume you're insinuating) to realize that relying solely on a very finite, heavily polluting fuel source that has already caused disastrous effects to the Earth is maybe not the smartest long-term play. That's not politics, that's just common sense and basic risk management. Not to mention the decades of propaganda, lies, bribery and other bullshittery that big oil has wrought upon us. You'd think people who call themselves true conservatives and free-market capitalists would be the first ones evangelizing against all of that, but apparently not.

Said collieries, which if put back into service, would be able to cheaply get coal to Ireland via barge at no great cost or latency.
Coal makes as much sense as a modern fuel as horse drawn buses do for transport.
In 20 years time China gonna be entirely powered by renewables while we’re still having this silly argument about what the future is going to look like.
How'd that work out?
Or, as Homer Simpson famously put it..."I dunno; Internet?"
But seriously, there's no significant recycling of solar panels, coal extraction is a known process, and good luck running an industrial economy exclusively on renewables.
There’s the direct answer to your question, cost of installed grid battery storage are getting cheaper by the user and it’s completely viable option at present. It’s not some vague fantasy idea like power plants in space or something, just look at California’s energy mix during peaks that in just a few years has become dominated by solar+batteries.
For longer periods of low-sun in a climate like Ireland see the other renewable options he mentioned. Plus a couple natural gas plants for fallback that can comfortably sit idle until needed.
If some combo of renewables are used 90% of the time when possible, no one is going to be mad about modern clean-burning LNG plants compared to a toxic, expensive relic of the past like coal.
Current trends make it clear the future will be renewables, grid battery storage, and however many natural gas plants are needed for reliability based on local climate (plus keeping nuclear online if you already have it). And that “future” is pretty much here already in places like California.
Places like California, which is right up there w/ Tunisia as the best-case scenario for solar, will have so much surplus electricity that USX and Tata are rushing to build steel mills there to take advantage.
Any day now, for sure.
No one ever claimed CA would have “so much surplus electricity that USX and Tata are rushing to build steel mills”.
Your “concern” was that there is no non-fantasy means to deal with transient output of solar or other renewables, I showed you how that is being implemented in the real world as we speak to deal with CA’s notorious peak evening load without blackouts. And it will only become more cost effective over time thanks to economies of scale.
CA has just started bringing grid storage online in the last few years but it’s already making an appreciable difference during peak times that in the past years resulted in blackouts.
It shows the clear, achievable path to a renewable + battery (+ nat gas) future that’s 95% renewables and highly resilient. Grid storage isn’t a “10 years away” fantasy like anti-renewable advocates might wish and it’s the critical piece to make those plans possible.
https://www.caiso.com/todays-outlook/supply
There will be when it’s needed in a decade or two. Right now solar farms installed recently have years to go until they’re decommissioned. There’s already processes for it.
They’re almost entirely glass and aluminium anyway. We know how to recycle glass and aluminium.
But it is abundant in Russia, Ukraine, Germany, and Poland. Also, there is nuclear power in France.
However, Russia and Ukraine are at war. Germany is willing to go green and destroy itself. EU hates Poland and other east European countries. And EU and the rest of the world can't disassociate nuclear power with weapons.
So I guess EU can enjoy their limited and expensive green energy.
No it's not. I'm not talking about the environment either, coal plants are just straight-up more expensive than gas plants and renewables.
Coal plants are necessarily steam turbines and not internal combustion, because coal is filthy and the mercury/sulfur/etc would wreck the guts of any machinery it goes through. Thus, it's only used to boil water.
Gas turbines don't have that problem, so they spin the turbine with the combustion products directly. They're far more efficient, the machines are smaller and cheaper, and because you don't need to wait for a giant kettle to boil before ramping up the power, they're far more flexible and responsive to demand. It also helps that the gas is fed with a gas pipe, whereas coal needs to be fed with a bobcat.
Which is why nobody is building new coal plants - they're way more expensive than gas plants, even if the gas fuel itself is more expensive than coal.
...except China, who is building coal plants at a pace never seen in history. Are they dumb, or...?
China is building everything at a pace never before seen in history. Partly because their construction industry is a jobs program, and their economy is so dependent on it that they prefer building things at a loss rather than not building at all. Which is financially dumb, but welcome to politics.
By the way, the round trip of: Sell and export your coal to manufacturers that burn that coal to produce electronic goods that produce energy, then buy that energy technology to power your own infrastructure, is certainly not cheaper than just burning the coal you mined yourself for your energy production.
Cheaper (ergo, more profitable) for the mining companies, yes. That's about it though.
Right now China is building out more solar and wind per year than than the entire total deployed solar and wind in the entire UK, and they’re only getting fast. Their ability build renewables now vastly outstrips their historical coal buildout and their rising energy demands. They’re well on their way to achieving net zero far faster than anyone thought was possible.
Way to high compared to what? Some countries do not even have a problem with prices but with capacity (Netherlands). They would be willing to pay but they do not have the grid to deliver where the thing is needed, and it's hard to build new grids in high density areas.
> It seems logical that ending the use of existing coal energy infrastructure lead to an increase of prises.
But doesn't this depend a lot on planning and investing in alternatives rather the just closing or not the coal? Sure, if you just close one source and leave everything else untouched prices will increase, but doesn't sound like the smartest approach overall...
So as soon as Germany lights up their gas powerplants, that follow gas prices (wars, etc), French nuclear electricity has to be sold for the same price.
aren't all/most electricity market working this way (pricing based on marginal price, aka pay-as-clear)?
pay-as-bid has other potential issues and might not be better.
The fundamental issue with electricity markets is that they cannot rely on any signal other than the electricity price to control whether a given plant will be running at a given time or not.
I think a real alternative would be to set-up an entity charged with negotiating prices with the electricity producers (which would also be a sort of partial reversal on the whole market thing in a lot of countries).
Are you talking about the marginal cost? Don't blame the govt, blame the economics textbook.
https://ec.europa.eu/eurostat/statistics-explained/images/th...
https://ec.europa.eu/eurostat/statistics-explained/index.php...
there are 2-2.5x times differences between highest and lowest, of 25-30 countries
And here is some current/future (??) prices/increases, which i have no idea where they come from:
https://euenergy.live/
Nuclear defeats coal in all of these aspects, aside from the high upfront cost.
But sure, nuclear is cheap if you ignore all those things.
Some figures on running costs: Coal costs about £62 per MWh - (£31 for the coal and £31 for the CO2 premium we already charge the energy producers).
As a fossil fuel comparison, Gas costs about £114 per MWh.
Nuclear - Hinkley C will cost about £128 per MWh - but likely to be even higher when it comes online. And we will be on the hook for this price as long as it runs, no matter how cheap renewables are.
You're comparing the cost for coal as baseload to the cost for natural gas as a peaker plant. When using both for baseload, natural gas is cheaper than coal and emits less CO2.
Meanwhile renewables are cheaper than both until they represent enough of the grid that you have to contend with intermittency:
https://www.ourworldofenergy.com/images/electrical-power-gen...
Which doesn't happen until it gets close to being a majority of generation, and which most countries aren't at yet so can add more without incurring significant costs for firming.
In other words, the currently cheapest way to operate a power grid, if that's all you care about, is to have something like half renewables and half natural gas. Add some nuclear -- even just, don't remove any -- and CO2 goes down by a lot because then you're only using natural gas for peaking/firming instead of baseload, while still having costs in line with historical norms.
The obviously bad thing many places are doing is shutting down older power plants without building enough new capacity in anything else to meet existing demand, and then prices go up. But that's not because you're using e.g. solar instead of coal, it's because you're trying to use demand suppression through higher prices instead of coal. It's easy to get rid of coal as long as you actually build something else.
Yes, all three. Building a nuke plant without the additional concern for outcome that we put on nuke would be relatively inexpensive. It's just concrete, pumps, and a turbine. It's a ismilar level of complexity to a coal plant. Same with running cost, same with decommissioning costs.
https://en.wikipedia.org/wiki/Kingston_Fossil_Plant_coal_fly...
Suppose we designed, operated, and budgeted every coal plant to make accidents like this a statistical impossibility. Not very unlikely, that's not the standard we hold nuke to. An impossiblity. Imagine what that would cost.
Even if you ramped down the safety, it still wouldn't be cheap or simple.
Industrial control systems are fundamentally sensors, actuators and a computer. None of those is actually that expensive. Nobody should be paying a billion dollars for a valve.
Older reactors have somewhat high operating costs because they're so old, many of them were built more than half a century ago. Newer reactors often have higher costs because of the lack of scale. If you only build one or two of something you have to amortize the development costs over that many units, mistakes that require redoing work are being made for the first time, etc. Build more of them and the unit cost goes down.
These are what makes it cost 5x solar or wind.
https://www.ourworldofenergy.com/images/electrical-power-gen...
Nuclear, inclusive of construction costs: ~$181/MWh, only better than natural gas because no CO2. Nuclear, cost of continuing to operate an existing reactor once it's already built: $31/MWh, basically the cheapest thing on the market, half the cost of continuing to operate an existing natural gas plant (because you need so much less fuel).
What this implies is that if you build a nuclear plant you're going to want to continue operating it for 80 years, and even then you probably want to just modernize it again instead of actually decommissioning it.
The long-term average returns from ordinary investments (e.g. S&P 500) are ~10%/year, implying that even if you require decommissioning to be prefunded (unlike any competing form of power generation), the amount of money you need is less than 0.05% of what the cost will be in 80 years. Adding $500 million in decommissioning costs isn't $500M in net present costs, it's only $250 thousand in net present costs, because you take the $250k and add 80 years worth of interest (1.10^80) which multiplies your starting capital by more than a factor of 2000.
It's really just the construction, and that's in significant part because you have to build more of them to get economies of scale for building them.
This is disingenuous. Bad math is focusing on the one part of nuclear power which is relatively cheap (fuel) and ignoring the rest where the majority of the cost is, which is what you did.
I wasnt comparing nuclear power to gas anyway I was comparing it to solar and wind which produce no CO2. FIVE times cheaper LCOE.
Nuclear power needs anyway to be paired with dispatchable energy source like batteries or gas just as solar and wind do.
It isnt a competitor with gas or batteries it is a complement to gas and batteries, just like solar and wind.
Only if you ignore all externalities including:
- environmental damage from mining (yes this exists for renewables too)
- global warming
- pollution on city infrastructure
- pollution on health
- the sunk costs causing higher transition costs when inevitably you transfer to renewables anyways.
Not even then. Coal is dead, and gas killed it. The externalities are a distraction, coal plants are just straight-up uneconomic.
Do not discount how easy that is to do. Your list is of costs not to any bottom line of a company with bean counters. Those external costs are out side the scope of their concerns. Your list of concerns would be something for C-suite types, but the pressure of stock prices again make the external costs easy to set aside.
https://en.wikipedia.org/wiki/List_of_high-voltage_transmiss...
The new one going to France will probably have the most impact initially, the French love to sell their Nuke's surplus capacity. The new British ones by the time they're finished should have access to British's big wind energy generation, much of which will be online at that point.
The claim of "previous underinvestment" ignores the massive capital outlays of the last decade. Ireland has actually seen massive investment in its grid to accommodate renewables, but the efficiency of that spend is questionable. We have a "constraint payment" system where we pay wind farms not to produce power when the grid is congested. In 2023 alone, these payments reached hundreds of millions of euros. This isn't "underinvestment". It's an operational failure to align generation with grid capacity, a cost that is hidden in the consumer's bill.
You suggest that "saving the world harder" (more renewables) would have lowered prices. This ignores the Marginal Pricing Model. In the Single Electricity Market (SEM), the price of electricity is set by the most expensive generator needed to meet demand - which is almost always a gas-fired plant. Therefore, even if wind provides 80% of the power at a given moment, consumers often still pay the "gas price" for all of it. Adding more renewables without reforming the marginal price auction system does nothing to lower the immediate cost to the consumer. It just increases the profit margins for renewable operators.
I should also comment on the source of that report: Nevin Economic Research Institute (NERI). NERI is not a neutral academic body. It is the research arm of the Irish Congress of Trade Unions (ICTU). NERI’s research is fundamentally rooted in Social Democratic and Labor-centric economics. Their reports consistently advocate for increased public spending and state intervention. By focusing on "underinvestment" and "network costs," NERI shifts the blame away from the policy failures of the green transition and toward a narrative that justifies more state-led infrastructure spending. They often downplay the impact of aggressive carbon taxing and the "Public Service Obligation" (PSO) levy, which are direct policy choices that have inflated Irish bills compared to the EU average.
Finally, the "poor connections to neighbors" argument is becoming obsolete. With the Greenlink and Celtic Interconnector (to France) coming online, Ireland is becoming one of the most strategically connected islands in Europe. If isolation were the primary driver, prices should be falling as these projects near completion. Instead, they remain the highest in the EU (often 40-50% above the average). The "island" excuse is a convenient shield for domestic policy inefficiencies.
They must have been real quiet. Most the protests are related to how expensive it has become to rent / buy in this country.
Ireland has encouraged and allowed a huge number of data centers to be setup here and been very slow to implement legislation for other green forms of energy generation. We don't need dirty forms of energy production here like coal and peat just to make energy cheap. Relying on Oil and Gas leaves us hugely at the whims of the international markets.
| now importing most of our energy
14.0% of its electricity in 2024 according to https://www.seai.ie/data-and-insights/seai-statistics/key-pu...
It's grid capacity more than anything which is the issue, and (like many other Irish issues) this is downstream of failures in our planning and permitting process.
In no other industry are providers ever worried about selling too much.
Also, both of these problems are caused by the same thing: NIMBY-ism.
Modern western governments generally hate people new building new things. Whether its a renewable energy project, a fossil fuel plant, a housing development, etc. It's all the same problem.
| NIMBY-ism.
True but it effects are much worse due to poor planning laws
Ireland is richer than it has ever been. Poverty and housing difficulties have nothing to do with reducing emissions.
Ireland partly got rich by being a massive CO2 polluter per capita. Now we are rich it’s only fair we lead in transitioning to renewables. Renewables are cheaper now than most forms of energy production. Grids need investment.
I despair at these short sighted and fairly wrong on the facts views.
Isn't that more about big tech companies using Ireland as a tax dodge, rather than a sign of average people doing well?
For less-well-off people, energy costs in the UK are a huge issue, they're more than twice what they were pre-Covid. Energy bills are second only to housing costs when it comes to the cost of living crisis. Although grocery price inflation/shrinkflation has been pretty shocking too.
This is a policy decision by the government. More realistically it is a decision to not proactively do anything and instead rely on market prices to encourage new entrants to the market.
https://www.cso.ie/en/releasesandpublications/ep/p-dcmec/dat...
In an ideal situation we would be seeing a ramp up in production of all types to take advantage of the costs.
Are you telling me that the electricity purchasing is like me purchasing from amazon, but but never charges shipping, or factor it into the products, and then suddenly cant ship because all trucks are used and no money to buy new?
What is your point?
It’s a massive topic and I encourage everyone to go and dive into it. It’s endlessly fascinating and also one of the really positive stories in the world right now which can help balance your emotions in a sometimes depressing world. At least for me it does.
It's also just a rule of economics. The price is set at the cost of the most expensive production necessary to meet demand.
So if solar could fulfill 100% of energy demand, price would be the cost of solar, and any other more expensive generation would either lose money, shut down or idle.
But if we shut down or idle those today we wouldn't have enough electricity, so the price rises until the more expensive plants can stay open and demand is met.
That rule is a rule of free markets. Electricity is not a free market, so it only partially applies. Texas is closer to a free market, and unsurprisingly it is adopting solar faster than most.
We appreciate your restraint.
If you build more solar it'll meet 100% of demand for a larger portion of the day, which is what we're doing.
This also demonstrated through most countries in Europe that citizens will vote to have government that fix the energy market. Citizens do not want a free energy market that can raise prices to any degree, and its their tax money that fund grid stability.
This all mean that the cheapest form of producing energy do not result automatically in reduced energy costs for consumers and companies. The product that people pay for is not energy in a pure form, it is energy produced at a given time and given location. Make the energy free but the time and location expensive, and the total cost will still be expensive.
Transmission can help Ireland, but it can also hurt it by linking it to a larger market that can create a even higher demand spikes than exist in the current local grid. If the linked grid has locations which has higher energy costs than Ireland, then Ireland will subsidize those people by linking the markets together. Rules like highest price regardless of source sets the price, and higher amount of transmissions, also tend to result in more companies getting paid to maintain operations and thus more parties getting paid that is not linked to the marginal cost of producing energy.
The people using carbon to create forcing functions to transition to renewables conveniently forget to mention that. Which sucks, as solar in particular is almost a miracle product, but at this point my delivery charges to get electricity exceed the electricity supply by 10%. 20 years ago, delivery was 30% of supply.
My state, New York, decided it would be smart to turn off the nuclear plant that supplies 20% of NYC electricity, and replace it over a decade with a rube goldberg arrangement of gas, offshore wind, solar, and Canadian imports. The solar is hampered by distribution capacity, gas was slowed down by corruption and is being limited by environmental activists, we elected a president that believes that windmills give you cancer, and of course we are picking fights with Canada now.
If you don't have competent government, that's not the fault of renewables.
This is not snark. With forward-looking rational planning the transition could have started decades ago, and we could have had a low carbon energy economy by 2010 at the latest.
But fossils make so much money they can buy the policy they want, and here we are arguing about national tactics instead of planetary strategy.
In a vast over simplfication, the most expensive producer that gets to supply sets the overall price. So even if you supply 99% from wind and hydro, the 1% of power that comes from gas sets the price for 100% of the electricity in the market.
When gas gets more expensive, electricity from gas gets more expensive. The more you have to rely on gas (because you don‘t have batteries, not enough solar, etc), the more you pay high prices.
There are different ways to address these issues. Demand side load management, batteries, etc.
The gas prices went up massively in 2022 with the war in Ukraine, and even though that subsided before the war in Iran a little, the existing supply companies are not going to give back an increase in the price they’ve gained because their prices dropped.
The tricky part here is that energy is an input to basically everything. It's a major (through fertiliser) input to food, and then all of transport and stocking of said food which tends to be how energy changes influence downstream inflation. So I think you'd probably need a deeper analysis to tease out these issues.
Talk about ill informed.
https://worldpopulationreview.com/country-rankings/median-in...
Sorry, what? While I agree with you about reducing emissions, most of our transition from poor to rich(er) was driven by capital light businesses. To be fair, the pharma companies did come here because we refused to regulate spillovers up to EU standards, but that's less than half of the story.
tl;dr loads of golf courses, english speaking population, smart industrial plannng and tax dodging was really how it happened.
Unfortunately it's not the people/generation who reaped the rewards from cheap energy and polluting who are now being made to feel the pain of the transition.
That’s why they are installing it all over their country at the fastest pace of any country by far? That’s why they probably hit peak oil consumption?
The coal thing is complicated in China. They are replacing many old coal stations, local governments are fearful of being caught short in a cold winter which has happened. Rate of coal consumption increases is slowing. Peak coal may have happened last year.
https://www.carbonbrief.org/guest-post-why-china-is-still-bu...
Hopefully this new info might help change your views.
>"China is the world's top electricity producer from renewable energy sources. China's renewable energy capacity is growing faster than its fossil fuels and nuclear power capacity.[1] China installed over 373 GW of renewables in 2024, reaching a total installed renewable capacity of 1,878 GW by the end of the year. The country aims to have 80% of its total energy mix come from non-fossil fuel sources by 2060, and achieve a combined 1,200 GW of solar and wind capacity by 2030.[1]
>Although China currently has the world's largest installed capacity of hydro, solar and wind power, its energy needs are so large that some fossil fuel sources are still used."
Seems more renewables came online than non-renewables, perhaps your take is outdated?
China is the world's top consumer of coal, and accounts for more than 50% of the world's total consumption of coal.
(second most populous after India)
Alternatively, if all Ireland was a city in China, it would not be in the list of top 50 cities by population.
I think the real takeaway here is that the world depends on the industrial production of China, which is powered by coal. We are all using that coal to buy cheap Chinese manufactured goods, and the sooner we come to terms with this the better. Whether a single country uses coal or not is irrelevant for tackling carbon emissions, if we're all basically exporting our carbon emissions to China.
India is building 41 coal plant, China is building 289. India approved 5 more plants, China approved 405. China is building more coal power than all other countries combined including India.
This thread is crazy. guys just look at numbers first...
https://www.carbonbrief.org/analysis-coal-power-drops-in-chi...
That's not the argument they made.
> "they know windpower and solar are not viable long term"
Thanks for the nonsensical, unsupported, right-wing talking points, throwaway account. Great contribution.
> "Web search how many Chinese coal plants came online in the last six months."
I web searched and found that "China installed a record 315 GW (AC) of new solar capacity in 2025". The entire UK national grid is currently providing 35GW of power from all sources combined. That's 1/9th of the power China deployed in just solar panels just last year. And China deployed 119GW of wind turbines in the same year as well.

Just assume it’s a clanker or propagandist and flag it imo
And are you sure about your claim? Every time I hear anything about China and Solar the core of it is that solar in China is growing more than anywhere else on the planet ( 40% increase in 2025 and creating ~11% of China's energy already )
And that there is no sign of that trend slowing down anytime soon. And why would it. Solar panels are dirt cheap and they have more than enough space for it.
China is also really strong in the battery space, so they have everything they need to ditch oil/coal eventually
That they have the internal political means to get large infrastructure projects done is laudible - they can actually build transmission lines that make unreliable energy sources like solar and wind feasible. In the US that is effectively impossible due to the NIMBY legal situation.
That they lead in battery production is going to be pretty interesting to watch. I admit I was skeptical that current battery tech could be scaled up enough to make it financially doable, but China is very close to making me wrong on the topic. If they can be the first to truly seasonal storage that works without hand-waving games like pretending you can "just use another source" when you run out of storage I'll be very impressed.
They seem to understand that you need to back unreliable sources with reliable sources - and have the political means to build a coal plant that will sit idle 95% of the time.
No other country is close - it's parlor tricks at the moment. China seems to understand how energy works, and that you need a reliable grid to run an industrial economy. They are very much being pragmatic in how they are building out everything they possibly can. The West has forgotten this.
Are they really? Coal use for power generation stopped growing, so newly built coal plants are replacing older, not adding to them. Nuclear while still being built does not seem to be accelerating anymore.
The US, under the current admin, is literally the opposite of that.
Everything is geopolitical now. Expect the hawks to look at the "success" of Iran and move on to bombing China soon.
So it appears they’re building more renewable capacity than coal capacity.
by the way also it shows increasing CO2 emissions from solar and wind. it doesn't make any sense
https://apnews.com/article/china-climate-solar-wind-carbon-e...
Why?
By 2020 it was obvious that wind & solar were viable long term, so investments in nuclear et al dried up. But they weren't convinced that batteries were viable long term, so they built a lot of coal peakers for night power.
By 2025 it became obvious that batteries were more viable and cheaper than coal peakers, so they've started to build battery storage at a vast scale.
So steelman is that the OP's viewpoint is ~10 years out of date.
they also know about batteries
I did and it was actually very few. In 2024 88% of new electricity in China came from solar and wind. https://www.eia.gov/international/analysis/country/chn
You should try doing some research instead of lying.
> Renewables are cheaper now than most forms of energy production. Grids need investment.
> Now we are rich it’s only fair we lead in transitioning to renewables.
> I despair at these short sighted and fairly wrong on the facts views.
The level of arrogance is unmatched while being both factually wrong AND self-contradictory.
Absolute cinema!
The huge energy price spikes are down to wars in Ukraine (gas, which is also used for electricity production) and the Middle East.
"TAIPEI (TVBS News) — Premier Cho Jung-tai (卓榮泰) announced on Tuesday (Nov. 19 2024) plans to subsidize Taiwan Power Company (台灣電力公司) with NT$100 billion to address rising international fuel costs and stabilize prices"
=> over $3bn USD! This is not a small amount of money.
Long term price stability is currently not something that is optimized for.
One way to solve it is of course abandoning the ide of a market economy for power.
Another is to let those industries that need price stability buy that on the futures market.
At the end of the day, it's a global market, and if you want it 'cheap' someone has to pick up the tab. Either it's taxpayers now, taxpayers in the future or consumers now.
https://www.taipeitimes.com/News/front/archives/2025/03/23/2...
Taiwan's energy policy is, as far as I know, the most pants-on-head stupid of any country in the world. As anyone knows, they are a small island at constant risk of a sea blockade and yet rely on sea imports for 98% of their energy. Not only that, but they _had_ more domestic production (nuclear) that they have been phasing out. Writing giant checks to import yet more oil by sea instead of boosting domestic production is a terrible idea for so many reasons.
Anyway your actual problem are data center buildouts that are causing demand to skyrocket. They've gone from 5% of your electrical demand to >20% in less than a decade, and are the primary cause of your electricity crunch.
Back in days of yore (2006/07) I read a well-argued policy paper from a quango that no longer exists where it pointed out that Ireland was one of the most fossil fuel dependent nations in the world (particularly due to oil imports).
Our energy prices first spiked around the same time, to "incentivise competition" in the words of a minister of the time.
All the while we have vast, vast reserves of potential wind energy sitting unused because of (mostly) grid and permitting failures. This was and is entirely in our control, but the government(s) (even with the sad exception of the Greens) simply haven't put enough resources into it (although the grid is getting investment, we need a lot more).
Also the critical infrastructure bill will (supposedly) help, but I'm sceptical as none of this ever seems to help.
Which is to say, that I completely agree with you that the costs here shouldn't be born by the poorer people in Ireland, and we need a whole of government approach to driving down the price of energy. This will take time, but the best time to start doing this is now.
My personal belief is that we should also aim to drive down the price of land, as the two biggest costs (for many countries) are land and energy, as they input into almost everything, but reducing land prices is a lot more controversial than reducing energy prices so we should start there.
> Ireland's energy import dependency was 79.6% in 2024, up from 78.3% in 2023 (for comparison, the EU average for 2023 was 58.3%).
> Ireland imported 100% of its oil, 79.5% of its gas, and 14.0% of its electricity in 2024.
From what I understand Ireland has very little natural gas, very little coal and a not particularly large amount of peat. If they didn't shift towards importing all of that would be gone in the very near future.
It's a bit weird how it gets branded as a solely green move when there's clearly other motives for it.
For practical purposes no coal. There are no working coal mines in Ireland, and Moneypoint would have run entirely on imported coal since it was built. It was built with a bulk handling terminal for this purpose (very visible in photos of the plant: https://esb.ie/news---insights/inside-esb/moneypoint-power-s...).
Note that it doesn't have a rail link; even if there had been the desire to use domestic coal and someone had gotten a mine going, there would have been no way to get it there.
https://progressireland.substack.com/p/irish-electricity-is-...
The only part of your bills that could be regarded as virtue signalling is the carbon tax, which is driven by government regulation. The vast increases in energy costs were driven firstly by Russia (when they invaded Ukraine) and the US (when they attacked Iran).
And this hits me too, I have (unfortunately) oil heating which has gone from about 500 to 800 over the course of the last week. Fortunately we filled up last month, but it's really worrying.
Ultimately though, the only way to fix this is to build a lot of wind (industrial scale) and solar (residential scale) as otherwise we're at the mercy of world events.
Again, our poor decision making around national infrastructure is on our governments. They left have left us completely exposed to international markets.
As usual with the Greens, perfection was the enemy of the good.
"My energy prices are high" because you are getting outbid. You can't stop getting outbid by building more transport infrastructure. That terminal will go unused.
Being dependent on gas is equal to being exposed to global shocks, unless you can cover your domestic needs purely with domestic gas extraction.
This is a weird way to justify using LNG brought in through Britain.
I'd add that this is only part of the equation because: what do you do on an overcast day with no wind?
You need significant storage capacity before you can become isolated from world events. Until then, you need power generation that you can bring online on short notice: coal, gas, hydro, etc. Traditionally, gas was used for this because it's easy to store, quick to get going and gas plants can also burn coal if needed.
Unfortunately, the nice properties of gas (easy to store and transport) mean that it's a global commodity. It will go where they pay the most, which means that far away events can cause a price in gas prices globally.
Battery technology is really, really getting there.
And in the absence of any more improvements here (unlikely) you integrate your grids with other countries. That's harder for Ireland, but it's still worth doing.
The sheer number of people in this thread saying, "we need renewables to be independent!", from countries that don't actually manufacture anything, is astonishing.
Also all these economies do make stuff, they just don't employ huge numbers of semi-skilled workers to do so. Most of the factory jobs are gone, but the factories are not. I live in a port city, about a century ago this city had loads of jobs crewing ships and loading cargo but today more work is done by a tiny fraction as many people.
And they're often disingenously included in fossil fuel pricing to claim that green energy is fundamentally cheaper.
I believe in climate change, and I believe in doing something about it. But being disingenous with the public is only going to create resentment and resistance to Net Zero.
There’s nothing unreasonable about this: fossil fuels have huge costs associated with them that are invisible to the consumer. They’ve just been getting pushed off onto other people forever.
But don't expect me to take you seriously when you directly compare a raw price of renewable energy with an uplifted price of fossil fuels.
Especially when your quoted price for renewable energy ignores the cost of grid upgrades, storage infrastructure, and externalities associated with mining materials to manufactur solar panels and wind turbines etc (as happened recently in UK parliament when the energy minister did a very dubious comparison between energy prices)
Solar panels can be recycled, so eventually they will need very little mining.
Have you ever recycled gasoline? Have you ever heard of the Deepwater Horizon?
I think you're being disingenuous while accusing others.
https://ourworldindata.org/grapher/coal-by-end-user-uk
Your emissions are dropping fast
https://ourworldindata.org/profile/co2/united-kingdom
It’s not box ticking it’s the complexity of change.
Per ton, yes. In practical, it’s far more complicated. Ships turn “heavy fuel oil” which is one tiny step from crude. It’s literally the byproduct that we have no better use for except for extremely large slow diesel engines.
If the tankers had to burn more useful fuel, we wouldn’t do it. The emissions on this unrefined bulk fuel is extremely bad.
Rail competes for efficiency depending on sea factors, and truck never does. But mining locally is far far more efficient that shipping literally to the other side of the world on ships that are burning 45 tons of fuel per day.
Australia I see but Japan? Japan is the world's third largest coal importer. I don't think they are sending much coal to England.
You can see here the electricity figures in Ireland: https://app.electricitymaps.com/map/zone/IE/all/yearly
> We've graduated from providing cheap energy to now importing most of our energy. We've seen huge energy price increases as a result.
Wrong. As you can see Ireland always produced a very limited about of electricity from coal, around 11% ten years ago when wind was 10% less. In other words, wind simply replaced coal, not imports.
For the last 50 years gas provides the bulk of your electricity, but Ireland produces virtually no gas and has always imported it. The jump in prices was due to these gas prices increasing due to the Russia/Ukraine war as of 2020, it had nothing to do with import changes. Had you invested more in wind/solar, you'd be affected less.
In fact Ireland barely imports anything at all, over the last ten years the net import are close to zero. 2025 was a peak year for imports but even then imports constituted a small 13%, whereas 2024 was a year where Ireland was a net exporter, as was 2020, and 2016, 2017, 2018, 2019. In fact of the last ten years it was a net exporter 7 times, more than twice as often as the 3 years it was a net importer. And its imported when the UK has cheaper electricity prices, otherwise there'd be no reason to import.
So your entire argument isn't true. Wind/solar can beat coal on a cost-basis now, evidenced by the fact that the average existing coal plant isn't running half the time because it's more expensive, let alone building out more coal. The smartest thing to have done is mass-invest in solar/wind in a country with a population density 4x lower than the UK.

Coal is literally just bad. It's hard as hell to transport, it's extremely inefficient to burn, and it produces a shit ton of harmful byproducts you have to clean up.
Why is it people can clearly see the recycling scam for what it was, but the idea of coal or carbon fuels makes them entirely unable to handle any sort of thinking that isn't entirely superficial and one-sided?
Maybe, like everything else in life, it's a complex series of tradeoffs, costs, and benefits, and you decide whether the cost is worth the benefit.
And if a policy being pushed doesn't make sense when all the costs and benefits are accounted for, then someone is doing something shady and making a shit ton of money, especially if there's a huge amount of smoke and mirrors and politicized talk.
Ireland's being used for things and it's obvious those in power don't care about and don't think the Irish people being affected by these sorts of policies can or will do anything about it. As that largely seems to be the case, I have to wonder if we're going to see a repeat of what seems to happen every time a government thinks that about the Irish and takes advantage of them.
> we've graduated from providing cheap energy to now importing most of our energy.
... Eh? We've always imported most of our energy. Or, well, okay, since about the mid 19th century we've imported most of our energy. All coal used in Moneypoint was imported. We do produce some of our own gas, but it is not and never has been enough. The fraction of energy that we import has actually fallen somewhat due to wind and solar.
And that's far outstripped by the current figure for renewables (42% in 2025) - so renewables have enabled locally-sourced production to reach more than double the share that was ever managed in the peat-burning days.
(And the comparison is actually even better than it seems at first glance, given that the 2025 figures are all-island and the peat figures would be 3 or 4 points lower if you included NI. A good chunk of the 23.2% imports can probably also be classed as renewable, given that GB had a 47% renewable mix)
As I browse the comments here I lament that most "above average IQ" folks still don't get this simple truth.
No if you allow to exit the simplistic low/high IQ paradigm you set up, I just can't take seriously comments like this who have not even started to try to show that they have any grip on the subject at all. Heck you haven't even tried to assess the quantity/availability of Ireland's "own resource". Do you seriously want Ireland to relay on peat ? How long would that last ?
On the other hand there are sock-puppets for oil billionaires who say it isn't happening.:
"Established in 2015, the CO2 Coalition is dedicated to “educating thought leaders, policy makers, and the public about the important contribution made by carbon dioxide to our lives and the economy.” The Coalition has received funding from the Koch brothers — the right-wing libertarian U.S. oil billionaires who have been at the heart of climate change denial in the United States"
https://www.ft.com/content/86fdb9e4-3db4-4e4f-8e47-580a1fad2...
Made some reasonable points imo
From what, turf? Back in the 1980s Ireland was importing coal from Poland because domestic mines weren't efficient. You're full of it.
Source for this claim? figures show 10-15% of power is imported, not "most", and those fluctuate with wind generation.
"China is by far the largest consumer and producer of coal in the world. Coal has historically been the backbone of China’s rapid industrialization and still plays a dominant role in its energy system."
- ~55–60% of China’s electricity comes from coal (varies slightly year to year).
- China consumes more coal than the rest of the world combined.
- Annual consumption: roughly 4–4.5 billion tons per year.
- China produces about 50% of global coal output
The west suffers while China does whatever it wants, at a Grand Scale.
Coal was almost 100% of China energy consumption only 15 years ago, with a bit of hydro. Today they are very aggressively shifting towards anything but coal, as you found in ChatGPT, to less than 60% of coal in the mix. For comparison, the US is almost at the same point today than 15 years ago, only significantly replaced coal with more gas. A country that is consuming about the same amount of energy since 2000, while China consumes 5x.
https://www.reuters.com/sustainability/climate-energy/china-...
BREAKING NEWS: China is big.
Of course, maybe the goal here is worth killing 4.5+++ million people per year. There are no perfect solutions; only compromises. Maybe many more will die if we don't act. [The IPCC estimates that an additional 250,000 people per year, between 2030 and 2050, will die from the effects of climate change.](https://www.who.int/news-room/fact-sheets/detail/climate-cha...) That covers all modes of death, such as famine. For those in the room doing the math, many times more people will die today by making energy more expensive. Activists are asking us to sacrifice millions of lives per year today to save an estimated 250,000 lives per year decades from now.
For this reason, I no longer support making energy more expensive. I support environmental efforts to reduce pollution, but I can no longer justify the high cost of human life associated with taxes on energy. Instead, I really think activists should focus on making energy cheaper. This means working on solutions to make renewable energy and nuclear cheaper per unit of energy than fossil fuels. That's a path to saving lives which I think most people can get on board with.
I mean, at least you shut down the coal plants, those are legit bad for the environment. Germans shut down nuclear which is clean.
In the UK, Net Zero politics means we are killing our own North Sea fossil fuel extraction, only to purchase North Sea fossil fuel from Norway, at an increased environmental (and financial) cost.
That's the kind of political lunacy the OP is aluding to.
About 50% of the retail price of petrol in Ireland is tax (excise + carbon + VAT).
Overall fuel taxation in Ireland is ~50%, compared to 15-20% in the US. Although to be fair, most of Europe is doing the same thing to its population (during a cost of living crisis).
Our biggest interconnect is with France which is 72% nuclear. Currently importing 3GW from them.
Our second biggest is with Norway which is 88% hydroelectric. Currently importing 1.7GW from them.
We're importing 0.2GW from Belgium which is partly gas and partly nuclear.
We're exporting power to Ireland, The Netherlands and Denmark.
Imports is 6-7% of current UK grid power. Most of our power comes from us burning North Sea gas.

I've personally spoken to people (who are otherwise quite environmentally aware) who suggest they'd never vote for the Green Party because they'd take their turf away. It's a tough sell.
Me too! That was a lot of work, and surprisingly hard to stack.
This has made me remember having to go out to the coal shed and fill up a brass bucket and then come back in all covered in coal dust.
I've not thought about That Smell in years!
In a perfect world we would want to reduce emissions as much as possible in every facet of life, but in the real world I think we should pick battles that have the biggest impact.
I've only so many shits to give, and people heating their homes doesn't rank.
CO2 from small amounts of rural home heating is probably not the big thing to be worried about, especially if local recent biomass, eg wood from forest management. But there are still nasties (PMs, biodiversity losses, etc) to be considered and that should be dealt with in due course.
https://www.gov.uk/guidance/selling-coal-for-domestic-use-in...
Hence, in order to have RES you need to emit CO2. Deal with this. The other option, and UK goes that way, is to purchase electricity when it is lacking, paying spot prices, that's why they have such a big electricity bills, economy is down, people get mad and vote psychos.
The solution is dead simple, as France example shows. Simply use nuclear power plants and does not bother with RES, as it does not make any sense now.
Maybe, when we have technology to store efficiently electricity at scale, we can start using RES. But we just do not have that.
The end result now is that electricity in Europe is the most expensive on the World, so all manufacturing is moved to Asia, who does not bother with climate that much, that's why, despite all Europe efforts, overall CO2 emission keeps growing.
I still find it staggering that people feel like this is something that needs to be said as if it’s surprising or a novel idea. Do you really believe smart people haven’t been working through these challenges for decades?
If you have to import fuel, it may happen that no ships can get through. Or the fuel becomes too expensive to buy because of war, natural disasters, or market forces. Ain't nobody turning off the sun or wind.
> Maybe, when we have technology to store efficiently electricity at scale
Actually we have it now.
Yes, but this rarely happens, so any potential solution should be designed around it being idle 99% of the time.
> Those power plants have about 1h cold start.
Gas turbines can spin up significantly faster. However, the weather is quite predictable, so it is unlikely that this will be needed. Besides, battery storage is the perfect solution as an ultra-fast ramp-up holdover source until the turbines are at 100%.
> Hence, in order to have RES you need to emit CO2.
Or you equip the handful of gas turbines you use to make up for that 1% gap in renewables with carbon capture? It's not ideal, but it is very much doable.
> Simply use nuclear power plants and do not bother with RES
... and have your electricity be even more expensive?
The tech exists - it's mostly just a matter of political will. The economics already justify it. People are making considerable money by starting up BESSs (Battery Energy Storage Systems) and doing time arbitrage on energy.
cf. Iberia, who recently learned that effective storage and intertial pick-up is integral to a stable and efficient power network, and are now spending heavily on both.
It's a pipedream. Yes it's cheap and efficient, but it requires the geography and the will to destroy a local ecosystem.
BESS is what will ultimately win. It's pretty energy dense and it can be deployed on pretty much any junk land location. The only fight you'll have is with the neighbors who don't like it.
My power company, Idaho power, is deploying a 200MWh BESS on a slice of land they've owned for decades near one of their substations. The hardest part has been the permitting (which is now done).
Edit:
https://www.nsenergybusiness.com/features/energy-storage-ana...
To cover Europe's need you only need to build 70 1.5 GW hydroelectric stations at a cost of $92 billion (in reality much higher) while greatly damaging ecology in large areas.
(The link has rather detailed info)
All of Europe. $1 Trillion USD. Oh, and that figure has already fallen by 1/3rd in reality and the article claims it should drop by half again.
And that seems to be assuming you only have wind power as input. The long lull periods that drive the high storage requirements are, as that article claims, caused by large high pressure air masses. High pressure systems like that often come with clear skies! Indeed, go look at weather history for that same 2015 period and you see that the skies were calm and clear, and precipitation was about half the "normal" amount for that time of year. While there is perfect correlation between a windless day and a night without sunlight, battery to get you through the night is trivial and solved far more cheaply than this article seems to understand. Enough battery to maintain 24 hour output for a solar farm is cheap enough to compete with fossil fuels. Long term, wind and solar do not correlate, so it's very rare to have long lulls in both at the same time.
So this article is leaving out important details and also is way more pessimistic than even it admits is true.
That also ignores that even in the "lulls", wind never seems to go to zero, so even in lulls, you can always just have more wind. Building 10x as much wind as you need is not as feasible as building 10x as much solar as you need though IMO.
Oh, and a very very very important fact: Renewable generation is almost entirely a one time cost, or one time every 30ish years on average. OPEX per kilowatt hour is dramatically lower than fossil fuels. In fact, today Europe imports 10 million barrels of crude oil a day, and at $100 a barrel (a number which will rise quite a bit in the coming months), Europe spends $1 Trillion every few years.
Europe's current energy spend is to buy an entire continent's worth of energy storage and just turn it into CO2 every few years. Every single day of crude oil import, Europe could instead pay for one of the Coire Glas model plants this article is doing the math with.
Storage is beyond feasible and will reduce energy costs.
Note: This article is about making wind energy constant over month long time scales, not about building enough storage to power Europe durably, so that explains some of it's misses, but also doesn't really explain much. The 2.1 TWh of storage it suggest would be enough to power all of Europe for 8 hours a day.
Nuclear plants provide base load and they are extremely fast at ramping up/lowering production. All modern nuclear plants are capable of changing power output at 3-5% of nameplate capacity per minute: https://www.oecd-nea.org/upload/docs/application/pdf/2021-12...
You don't shut down power plants. None of the power plants ever do a "fast cold start"
> The end result now is that electricity in Europe is the most expensive on the World, so all manufacturing is moved to Asia
The production moved to Asia due to extremely cheap labor, not due to electricity costs.
And all of this is confused by the way the nuclear industry uses the term "load following". You'd think it means "changing the power output from moment to moment to match electricity demand" but for nuclear plants it means "changing from one pre-planned constant level to another pre-planned constant level, up to four times per day".[0] There are only three[1] sources of electricity that can be ramped freely enough to exactly match demand: hydro, simple-cycle gas turbines and batteries. All electrical supplies will need some of those three mixed in. Which is why France is still 10% hydro and 10% natural gas in their electricity supply.
0: Some of the most modern Russian plants can move to +-20% of their current target at 10% per minute, but "the number of such very fast power variations is limited, and they are mainly reserved for emergency situations." per your source.
1: OK, there are some obsolete ways too, like diesel generators. At least obsolete at the scale of the electricity grid.
5% of nameplate capacity.
> You'd think it means "changing the power output from moment to moment to match electricity demand" but for nuclear plants it means "changing from one pre-planned constant level to another pre-planned constant level, up to four times per day"
Which is clearly invalidated by the very source I provided, and which you then somehow quote back at me.
> "the number of such very fast power variations is limited, and they are mainly reserved for emergency situations." per your source.
Imagine if you didn't omit the full quote/context:
--- start quote ---
Also, AES-2006 is capable of fast power modulations with ramps of up to 5% Pr per second (in the interval of ±10% Pr), or power drops of 20% Pr per minute in the interval of 50-100% of the rated power. However, the number of such very fast power variations is limited, and they are mainly reserved for emergency situations.
--- end quote ---
Oh look. What's limited is an actual emergency ramp up of 5% per second or power drops of 20% per minute.
Which is literally an emergency that is not needed in a power grid.
---
Let me quote page 10 of your source "In brief, most of the modern light water nuclear reactors are capable (by design) to operate in a load following mode, i.e. to change their power level once or twice per day in the range of 100% to 50% (or even lower) of the rated power, with a ramp rate of up to 5% (or even more) of rated power per minute". Your own source defines "load following" as changing the targeted power level once or twice per day.
Again on page 14 (about how the French currently run their nuclear plants): "The nuclear power plants operating in the load following mode follow a variable load programme with one or two power changes per period of 24 h". Weirdly enough this is contradicted by table 2.1 on page 20 where they do four changes per day.
---
> Oh look. What's limited is an actual emergency ramp up of 5% per second or power drops of 20% per minute.
If you look at table 2.4 on the same page it states that it (the Russian VVER-1200) can do the 5% per second/20% per minute emergency change 20 000 times over the lifetime of the reactor. The 10% per minute change can also only be done 20 000 times over the lifetime of the reactor. Table 2.2 on page 21 helpfully calculates that 15 000 cycles is once per day for 40 years, so the VVER-1200 only can do a bit more than one >5% change per day (outside of emergencies) assuming a similar 40 year lifespan. And that was the point of my footnote: that nuclear plants technically can go faster than 5% but not up and down on a minute-by-minute basis.
> None of the power plants ever do a "fast cold start"
Somewhere in each grid you will have “black start” capacity contracts, dunno if nuclear can fills this role (or if grids exclude nukes for one reason or another).
Plenty of peaker plants built with the intention of running double digit hours per year and therefore the tradeoff supports being largely “off” in between those calls. Batteries might fill that gap.
The obvious counterexample is Chernobyl, where a big contributor was the fact that they were unable to scale it down & back up as desired. Yes, nuclear reactors can scale down rapidly - but you have to wait several hours until it can scale back up!
Besides, the linked paper only covers load-following in a traditional grid (swinging between 60% and 100% once a day) and barely touches on the economic effects. The situation is going to look drastically different for a renewables-first grid, where additional sources are needed for at most a few hours a day, for a few months per year.
> You don't shut down power plants. None of the power plants ever do a "fast cold start"
Gas turbines can. Hydro can. Battery storage can.
If you are going to curtail, you curtail other sources including solar and wind.
Nuclear fits quite well for the baseload you need. It's more expensive, but if you are going to need X capacity 24x7 and build nuclear, you simply build enough to provide just that plus perhaps a few extra for redundancy when another one goes offline. Then use gas peakers for the "oh shit" days difference between what nuclear is providing and solar was expected to but could not.
I don't understand the fascination folks have about nuclear not being able to following the grid. They don't need to, since they only ever remotely make sense when operated 24x7 at 100%. If you always have 1TW of grid usage every night during your lowest usage period - build that much nuclear as your starting point and figure out the rest from there. Nuclear's share of the total mix should be a straight line on a graph outside of plant shutdowns for maintenance.
Your argument only works in entirely state controlled systems, not in free energy markets of independent suppliers. Which is why nukes don’t get built.
You mean the obsolete design that is not used even in old reactors, not to say of modern designs?

The minimum requirements for the manoeuvrability capabilities of modern reactors are defined by the utilities requirements that are based on the requirements of the grid operators. For example, according to the current version of the European Utilities Requirements (EUR) the NPP must at least be capable of daily load cycling operation between 50% and 100 % of its rated power Pr, with a rate of change of electric output of 3-5% of Pr per minute.

> The situation is going to look drastically different for a renewables-first grid, where additional sources are needed for at most a few hours a day, for a few months per year.
Ah, to live in these mythical times...
However, every other number in the piece is mentioned as some multiple of Wh's (GWh typically). That makes it very hard to tell what proportion of capacity was removed from the system as a proportion of the total generating capacity. I think the writer might have served us better with the use of some helpful percentage comparisons.
From the SEAI report (2024) (https://www.seai.ie/data-and-insights/seai-statistics/key-pu...)
- Electricity demand in Ireland was 32.9 TWh in 2024, up 4.1% on 2023-levels
- Commercial services, which includes the ICT sub-sector, accounted for 41.2% of electricity demand.
- The residential sector accounted for 25.5% of electricity demand in 2024.
- Data centres accounted for 21.2% of all electricity demand in 2024.
- Data centres account for 88.2% of the increase observed in Ireland’s electricity demand since 2015.
If I've done my math correctly, Moneypoint generates about 8TWh, if operating continuously; which it's probably not. Can we say 6-7 TWh?
That is not an insubstantial portion of the total.
Our goal shouldn’t be to be coal free. Our goal should be to be 100% renewable.
If we set up our goals in terms of what we don’t want, we end up in the situation we are right now: high energy costs, very dependent on energy imports and a high risk of loosing our industry
No, our goal is to reduce CO2 emissions as quickly as possible.
Shutting down coal plants is a quick and easy win, as pretty much every possible replacement is less polluting. It might even make sense to replace them with gas turbines: base load today, peaker plant tomorrow, emergency source later on.

100% renewables is the exact opposite of "100% non-renewables" and that's including also oil, gas, etc. So "coal" is only a part of the 100% non renewables, but it seems your goal is to get rid of all the non renewables.
And here the question is: why would you want a single goal? Why 100% renewable?
What drives us should be: save where it makes sense, don't where it doesn't. Iterate every 10 years and recheck.
All these single radical goals are literally killing our economy and society. And I am not just talking about coal free or renewable.
Even the "let's tear down the windfarms" is dumb because it's radical and non sense.
Or unrelated, even this "we need to digitalize everything" (although given our jobs we would profit the most) can lead to a lot of problems (privacy, security, etc).
I don't know why we have become so radical in the last 20 years.
Overlapping goals can coexist on varying time frames.
Setting aside nuclear (technically not "renewable", but also not carbon-based, and very energy dense) the goal is to stop releasing CO2 into the air from energy generation and return to pre-industrial levels.
This is because the surplus of CO2 generated so far has already caused clear and undeniable problems (not all of which are yet fully realized), and continued excess will only make things worse.
> What drives us should be: save where it makes sense, don't where it doesn't. Iterate every 10 years and recheck.
Solar is already economically competitive in many places and is expected to improve further.
I really hope they just turn heavily toward renewables. We have enough offshore wind in Ireland to power most of the world, if we could just build enough turbines and harness it. We could become a net exporter of green power
https://ember-energy.org/data/electricity-data-explorer/?cha...
Look at the nuclear buildup. Vogtle in US 10 years. Hinckley Point C is estimated to be 13 years. Flamanville 3 took 17 years. All these years you put money in and get nothing out. It's a disaster for balance sheet. Instead, you can build renewables plus batteries and have it connected within a year, generating revenue.
As of 2025, the cheapest levelized cost of energy is solar ($58), onshore wind ($61), and gas combined ($78).
Although the data is US-based, European prices likely follow a similar pattern.
[0] https://www.lazard.com/media/5tlbhyla/lazards-lcoeplus-june-...
But the simple matter is thought that the economics of nuclear power simply are not delivering. They are expensive and slow to build, while at the same time wind (particularly off shore wind) and solar are getting cheaper and easier to build every year (or month even). Germany also stands out as a success story of nuclear phase-out, that by replacing these expensive to run nuclear power plant has offered the economic wiggle room to phase in renewables a lot faster then otherwise.
Here is the dashboard for electricity in Ireland.
Ireland is not industrialised in a similar way to other EU countries like Germany or Italy which has lots of heavy manufacturing. Irish industry is mostly composed of US pharmaceuticals and data centres occupying much of the energy demand. There is a bauxite facility in limerick which does come to mind but that sort of thing isn't common in Ireland.
It addresses key questions such as "What about China?" and "Can we stop it?"
[1] https://www.goodreads.com/book/show/222768021-clearing-the-a...
Poland I guess?
As such, it's not really the whole story to call Ireland, "coal-free". It's the same as America outsourcing heavy manufacturing or chemicals to China and claiming environmental victory. It's true in a narrow construction of the concept; it does reduce the burden on one's own country. It is false in the sense of one's contribution to the global commons and externalizes those externalities previously more internalized. It is, in other words, a shell game. Ireland's dependence on imported energy continues to rise and the number continues to tick up on the books of other nations and down on hers, with her people paying the "guilt premium" associated with this accounting trick. They're not exactly dirty grids, but the fact remains, Ireland still relies to some extent on coal.
Also note that, though she is building OCGTs and fast CCGTs elsewhere, she converted Moneypoint not to gas but to heavy fuel oil. HFO is quite dirty stuff, only a dozen or so per cent cleaner than the coal it replaces per Ireland's own EIS. This is likely influenced by the fact that the plant was specced to burn some of the cleaner thermal coal on the market, largely from Glencore's Cerrejon mine, with pretty low sulfur and ash relative to others. So, the delta from relatively clean coal (excuse the expression) to some of the dirtiest oil; large boilers like that are likely burning No. 5 or 6, aka bunker B or C in marine. Not sure if you've ever seen (or smelled) this stuff but it's the next thing from tar.
Ireland could instead have chosen to pull in gas from the North Sea and reduced the emissions of Moneypoint by not twelve but fifty to sixty per cent with modern CCGTs. Even older, more readily-available OCGTs would give thirty to forty per cent. This is ~250mmcf, i.e. probably a 24" spur line. Though this likely necessitates a few hundred km of loop for the ring main to the west, it's less than a year's work with a competent American crew.
Instead, she chose a paltry twelve per cent a few years earlier; when the other gas peaker capacity is installed, cooling infra and existing thermal plant talent base while paying to reconstitute all those on the other side of the island.
None of this is to say Ireland's work on decarbonizing her grid isn't real, but "coal-free" rather tends to obscure the present state of things; it is generally understood to make a strong, binary truth claim that isn't subject to "mostly" and implies one is no longer dependent on coal. It therefore demands consideration of electricity's fungibility in a grid.
https://www.eirgrid.ie/celticinterconnector
Ireland has lots of problems including energy generation but you're not being fair in citing significant progress having been made here.
Your entire comment is incredibly misleading.
The way to think about this is, "If the grid had zero reserves and coal cut off, who could POSSIBLY go down?" You may figure this is constructed, but in a few days' dunkelflaute, Ireland needs her interconnects. Wind is then possibly low across much of Europe, meaning Holland and Germany ramp dispatchable capacity, including German lignite.
Denmark has one coal fired power plant left, set to close in 2028.

Good luck repairing your renewable energy infrastructure if you're hit by one of many different classes of attacks.
Coal and coal-burning energy production is an insurance policy, at the very least.
Countries have been getting rid of their oil refineries as well, and now look what is happening to those countries, given the Iran situation. Their price of fuel is skyrocketing, their reserves are dwindling, and panic is setting in. Hope is not a strategy.
Relying on third party supply chains for key infrastructure that would result in mass casualty if it were to vanish, is not intelligent. It's a vulnerability.
Nuclear discriminates against capitalism. The cost makes the choice of nuclear irrational. The inability to insure nuclear in the private market makes it a travesty of free markets.
> The new analysis for Carbon Brief shows that electricity generation from coal in India fell by 3.0% year-on-year (46 terawatt hours, TWh) and in China by 1.6% (90TWh).

do you have any other questions?
1. There are coordination issues that have caused them to overestimate the need for such plants, which have been running at low capacity. There have also been perverse incentives to build plants that weren't needed, in order to placate the relevant stakeholders.
2. Battery storage (including pumped hydro) is being pursued aggressively, specifically (among other things) to address the reliability concerns that motivated the recent new coal plant construction. Government policy, furthermore, is clearly focused on "new energy", i.e. not fossil fuels.
3. Coal power generation in China has been level or declining for a little while now. Generation from new renewable plants is outstripping the overall increase in demand for power. There is a graph titled "New coal power has no predictive value for future coal power generation".
4. Historical, global evidence shows a persistent trend of capacity reduction lagging behind generation reduction. As should be expected. It takes effort (= money) to decommission a power plant, and an inactive (or less-active) one is a safety net. "In most cases, what ultimately stopped new coal power projects in those countries was not a formal ban, but the market reality.... In China, the same market signals are emerging: clean energy is now meeting all incremental demand and coal power generation has, as a result, started to decline."
5. As a share of total power generation, coal power in China has dropped substantially (from nearly 3/4 to scarcely half) over the last decade or so. In absolute terms, it is likely near or even past the peak.
6. The article concludes: "While China’s coal power construction boom looks, at first glance, like a resurgence,it currently appears more likely to be the final surge before a long downturn. The expansion has added friction and complexity to China’s energy transition, but it has not reversed it."
You asked:
> So are China, generally shifting away from coal?
Your own source clearly argues that they are, in fact, shifting away from coal. Presenting an article that refutes you as if it supported you, while employing this style of repeated "pointed" questions, is disingenuous and obnoxious.
It invalidates the rhetorical question by pointing out how it is irrelevant to your original position.
If only they could harness the power of rain, Ireland would truly be an energy superpower.
[1] https://www.irishtimes.com/special-reports/2025/10/30/winds-...
I know this is in jest, but that's basically "dam up some valley rivers and put a hydroelectric generator on the end", and unfortunately Ireland isn't so good for that. (It's not just the physical geology, it's also all the people living in the places you'd flood).
Hydro as a battery is easier and works in far more locations, but that's not harnessing the power *of rain*.
But yes, Ireland and the UK have an absolutely huge wind power resource available around them, IIRC enough to supply all of Europe if the grid connections were there to export it all.
Prof Igor Shvets was behind this: https://en.wikipedia.org/wiki/Spirit_of_Ireland
Onshore wind in England was de-facto but not de-jure banned by the Tories in 2018, due to a footnote inserted in their National Planning Policy Framework. Labour removed this footnote in 2024, immediately after winning the election. [0]
Offshore wind was never affected, nor onshore wind in Scotland, Wales or Northern Ireland.
[0] https://www.gov.uk/government/publications/policy-statement-...
However, it does matter, when looked at in whole with the need for capacity in the National Grid. A pile of turbines across SE England would have really helped, because a lot of the offshore wind and Scottish wind power has to be dumped, and gas generators fired up instead, due to lack of grid capacity to distribute that power across the country.
We should, of course, have completed upgrades to the grid by now, but they're late.
Here's a great article about "curtailment" as it's known: https://ukerc.ac.uk/news/transmission-network-unavailability...
For those who don't know, Ireland operates an all-island grid, and EirGrid (the grid operator for the Republic) owns SONI (the grid operator for Northern Ireland). That means that 'UK' and 'Ireland' in this has a large Northern Ireland shaped lump of ambiguity that statement.
Don't tell me EirGrid's EWIC that comes onshore at Dublin and Greenlink at County Wexford are an "NI-shaped lump". They are sources of electricity for the whole island, when it's needed, just like the UK's interconnects with the continent.
https://en.wikipedia.org/wiki/List_of_high-voltage_transmiss...
... Eh? No it didn't; not sure where you got that.
Ireland and the UK sell power to each other on a demand basis, though in practice Ireland is usually a net importer: https://www.smartgriddashboard.com/all/interconnection/?dura...

So still claiming that we didn't build any wind power was false.
In 2000, coal was about 20% of the energy mix, gas another 20%, oil about 50%. Wind was 0%. In 2024 coal was about 2%, gas still 20%, oil still 50%, but wind grew to about 15%. It seems that wind actually replaced coal. It is not only logical, but good, that wind first replaced coal (dirtiest), and maybe from now on is will start to replace oil. Only after many decades, or maybe never, gas will be replaced.
https://www.seai.ie/data-and-insights/seai-statistics/electr...
https://ec.europa.eu/eurostat/web/interactive-publications/e...
(2023 numbers)So natural gas was just barely more than renewables in 2023, but according to the source below the line was crossed in 2025 and renewables now provide more than all fossil fuels put together:

https://ourworldindata.org/grapher/energy-consumption-by-sou...
(Moneypoint was actually built originally due to Ireland's over dependence at the time on oil for power generation; after the oil crisis, initially ESB attempted to build a nuclear plant (https://en.wikipedia.org/wiki/Carnsore_Point#Cancelled_nucle...), but it was such a political minefield that it was canceled, leading to Moneypoint.)

It would feel weird to see this as a headline on a newspaper or on TV today, but maybe that is just me and people like to read new that are from last year.
India is still developing and per capita uses a fraction of the western world.
But globally solar and battery use are exploding. We really are living in the green revolution that was so talked about in the 90's and 2000's
India has vast coal reservers, and is the second largest producer in the world, whereas they aren't a major oil producer. Hence they use coal. Similar with China.
If the story was about some country shutting down their last natural gas plant instead of their last coal plant, no doubt someone would be pointing out that meanwhile the US is increasing natural gas production at a record pace.
In 2025 the US added 7 GW of natural gas electricity capacity, and India added 7 GW of coal. Natural gas generates about 1/2 the CO2 as coal, but India has over 4x the population, so the US added about twice as much new emissions per capita.
But we also need to consider how much renewables were added. That will be part of point #3.
2. India's emissions are 2 tons per year per capita, which is under 1/2 of the global average, which is about 1/3 the EU average, 1/5 of China, and 1/7 of the USA. Even if it takes them longer to get off fossil fuels than the other large countries they are likely to never come near the emissions levels per capita of those other countries.
3. They are actually making better progress at this than most others. 50% of electricity used in India is renewable, compared to 25% in the US, 40% in China, and 47% in the EU.
They are not just adding coal. They are adding wind and solar at record paces too. In 2025 they added around 7 GW of coal capacity last year, 38 GW of solar, and 6 GW of wind.
The US is doing the same, but with natural gas rather than coal. 7 GW of natural gas, 25 GW of solar, 13 GW of wind. About the same percentage of renewables (~90%) as India.
4. Yes, per capita is the correct measure, because the atmosphere is very efficient at distributing CO2 emitted anywhere to everywhere. A ton of CO2 has the same impact no matter where it is emitted. Unless you can make a good argument that some people have some sort of natural or divine right to a bigger share of whatever CO2 budget we decide Earth can afford, it has to be per capita.
In 2024 88% of new electricity in China came from renewables. https://www.eia.gov/international/analysis/country/chn
They build new coal plants as a backup, or to replace existing older plants. But they're very clearly not using them more than they already were. They burn coal because they have coal, just like the US burns gas because the fracking boom made gas cheap.
India is not doing as well as China but it is still improving. In 2024 64% of electricity growth came from coal, but that's down from 91% in 2023. https://ember-energy.org/countries-and-regions/india/
I think they'll follow China's lead soon. The economics are inevitable. Ember projects India will be at 42% renewable electricity by 2030, up from 10% today. This is obviously staggering renewables growth in a poor country.
The same source projects the US will be at 59% by then https://ember-energy.org/countries-and-regions/united-states... and it's already at 58% today. So basically 0 renewables growth in the richest country in the world.
Both India and China lack oil. Reducing fossil fuel usage is a national security issue for them. They're also poorer. As solar and wind become the cheapest sources of electricity, thanks mostly to China, they're going to rapidly transition. No dumb political games.
It's not greyed out for me, either.
> being motivated by various political outgroup boogeymen
If OP wasn't lying then they were misinformed. I made reasonable guesses to the source of that misinformation. I didn't attribute any political motives to OP themselves.
I don't see how "right-wing" or "right-wing media" is an "outgroup". And it isn't a boogeyman because the majority of the "climate change is fake but it's China's fault anyway" opinion pieces come from there.
Did you also flag OP's lies/propagation of incorrect information? If you did, I appreciate your consistency and fair-mindedness. If you didn't, then why not? What's worse - lies/propagating ignorance or being slightly curt?
Btw OP told this same lie 2 days ago: https://news.ycombinator.com/item?id=47282625 and was corrected by someone else. They are clearly not a good faith poster.
China is far more serious than the EU about the green transition. Despite being poorer than the poorest EU country they are dominating renewable deployment.
I think that attitude is poorly informed whataboutism.
https://en.wikipedia.org/wiki/Life-cycle_greenhouse_gas_emis...
Coal, with any available technology, is more polluting than any renewable energy source. Full life cycle including plant installation included.
