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.

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.

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.

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. 1-2% fossil energy in the mix is to me not really significant, and especially not considering how much fossil free power is exported.

So I think it's untrue to say that Sweden doesn't rely on coal power. Without coal power it'd have regular blackouts. I rely on being able to take a breath every couple of seconds. If I only get an annual average of a breath every few seconds, I'll die.
One could show great generation and net export statistics with a sufficiently large batteryless solar installation, and still import coal power every night and cloudy day.
What is true, but can easily imply an incorrect conclusion, is that Sweden's very good in being self sufficient in clean power generation statistically. Yes, very much true. But it's largely due to geography, and not merely something to replicate. Sweden has way more viable places where hydro could be installed, than most countries (though where economical and otherwise acceptable, it already has). And it's sparsely populated; Sweden is bigger than the UK, but with one seventh the population. So if the implication is that "if we can do it, so can you" then that's false.
Luckily the political wind (including population opinion) has started to turn in favor of nuclear power, again. Maybe everything can be solar in 100 years, but we can't have 100 more years of coal.

Anyway, my comment was in response to the extreme comment (parent) about how all rich countries became rich using fossil fuels - implying that that's the more or less only way to transition from poor to rich. I think it's important to note that that's not necessarily the case. You don't need to destroy the environment to go from poor to rich, even though a lot of countries historically have done it that way (also noteworthy that they did it without knowing about the consequences for the environment).

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.
Comment by derriz 1 day ago
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.
Comment by sh34r 1 day ago
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.
Comment by jillesvangurp 1 day ago
- 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.

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.

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.
Comment by derriz 1 day ago
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.
Comment by avianlyric 1 day ago
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.

Comment by Gareth321 21 hours ago
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.

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?

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.
Comment by panick21_ 3 hours ago
The exclusion zone is nonsense because many that live in that zone has lower cancer rates then those outside. The idea is based on a invalid assumption about radiation an a linear relationship between radiation and harm. An I do think the standards we apply are to extreme in many cases mostly dating back to this misunderstanding about radiation.
As for the locality to nuclear plants and cancer, this is as far as I know been shown in many countries and as far as I know at least can mostly be explained by nuclear plants usually being built in industrial areas that often used to have coal plants and other industry going on.
> nuclear reactors are there for the spicy atoms, not the price tag or public safety.
Not sure what 'spicy' means in this context. In terms of price tag they are objectively a fantastic deal if built in larger numbers. Even in places where they were not built in the numbers they did in France, they are good life time deal, and give relativity stable long term prices.
And they don't have to be 'there' for public safety, they just need a good record on public safety and they do.
In places like Austria and Germany we have many known cases where a nuclear plant was planned and was prevented by activists, only to be replaced by coal, in both cases impacting 10000s of lives being worse financially in the long term.

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 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.

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.

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.

Comment by Imustaskforhelp 1 day ago
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.

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.

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.

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.

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.

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.

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).

Comment by mrguyorama 1 day ago
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 production moved to Asia due to extremely cheap labor, not due to electricity costs.
Comment by sehansen 1 day ago
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.

Which is clearly invalidated by the very source I provided, and which you then somehow quote back at me.

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.
Comment by sehansen 19 hours ago

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.

If you keep jumping around with your arguments, nothing is extreme.
Your original claim started with claiming cold starts (which most power plants including gas turbines don't do, ever) and that coal and nuclear aren't fast.
Nuclear is plenty fast.
I never claimed gas power stations were slow, or that they were slower than nuclear.
> 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

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.
Comment by crote 1 day ago
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.

Gas turbines can. Hydro can. Battery storage can.
Comment by phil21 1 day ago
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.

Nukes don't get built because:
- billions (if not trillions) of subsidies were poured into wind and solar over decades to make them viable while nuclear energy was addled with additional taxes, reactor closures, and very few new reactor licenses
- decades of fear-mongering led to loss of expertise in building new nuclear power plants (and instead South-East Asia has been picking up speed in building new reactors) [1]
In 2015 nuclear was significantly cheaper than most other types of energy across most markets: https://world-nuclear.org/images/articles/REPORT_Economics_R... (Figure 12, in some markets including the then-emerging renewables). And yet renewables were enjoying unprecedented amounts of subsidies and money poured into them while nuclear... Oh we know what was happening to nuclear, just look at Germany.
[1] Here's EU's own report: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=COM:2025...
Renewables: 80-80 billion euro in subsidies a year.
Fossil fuels: 60-140 billion euro in subsidies a year.
Nuclear: good luck finding the thin orange line in the graph. (1% of subsidies)
--- start quote ---
As shown on Figure 4 , solar energy received by far the largest share of subsidies, both historically and in 2023 (EUR 21 bn), followed by biomass (EUR 9 bn) and wind power (EUR 7 bn). Hydropower received marginal financial support (~EUR 1 bn), while subsidies targeting multiple renewable technologies (such as tax reductions on green technology or public aid for investment projects) jumped to EUR 23 bn by 2023.
Subsidies for nuclear energy dropped from EUR 7.9 bn in 2021 to 3.7 bn in 2022 and 4.1 bn in 2023. Of the 14 MS providing nuclear subsidies, France (EUR 2.9 bn) accounted for the biggest share, followed by Germany (EUR 0.8 bn) , Spain and Belgium (EUR 0.1 bn each).

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.

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.
Yes, burning coal causes lots of problems and I support ending it's use, but this is besides the point.
Comment by jmward01 1 day ago
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.

You've not cited anything for this so far as I can see, but this claim is obviously false.
Reason being, the entire system in my driveway will have paid for itself in one year, including delivery cost and inverter and the aluminium stand it's mounted on (the small bit of aluminium in the stand is the most energy intensive part of the whole kit), and the weakest part of that system still has a lifespan of 25-40 years, and even that as a % reduction in output from peak not as a hard cut-off.
Even if 100% of the cost was energy, even with the 5x price differential between where I am (Domestic Germany) and where they were made (Industrial China, where the low energy cost is… ah… due to renewables, because coal's really expensive :P), it's obviously not an ERoEI of 4 even on the low end of that lifespan.
Given all that and doing the maths, what I will need to replace and when (or rather, kids whose mother I have yet to meet will need to replace when I'm in a retirement home), the ERoEI is at a minimum 14 even if 100% of the cost of replacement panels is energy.
The cost is almost certainly less than 100% energy. Every step of the industrial process wants its own profit margin.
Comment by NoLinkToMe 18 hours ago
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.

> 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.

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.

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.

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.

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.
Comment by AnthonyMouse 1 day ago
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.
Comment by idiotsecant 1 day ago
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.

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.

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 majority of the cost is construction, which is expensive when you're trying to amortize the costs of a plant design over only one or two plants instead of a hundred, which is what I said.
> FIVE times cheaper LCOE.
Five times cheaper as long as you want the most output when the market price is the lowest and the least output when it's the highest. And "five times" is with existing subsidies.
> Nuclear power needs anyway to be paired with dispatchable energy source like batteries or gas just as solar and wind do.
Nuclear power is baseload. All three of those do different things.
Suppose you have 10 GW of minimum load (e.g. late evening to sunrise) and 20 GW of peak load (e.g. late afternoon to early evening). Then nuclear is good for the former and solar+storage is good for the difference between the former and the latter.
To begin with, solar output actually partially aligns with the latter. Load is higher during the day. It's also high just after sunset, but that's only for a couple hours, and then you don't need a lot of batteries to cover it, which you can charge with more solar. But you'd need a lot more batteries (or gas plants) to make it through the whole night. That kind of sucks if load looks like it currently does, and it really sucks if you want people to switch from fossil fuels to electric heat, because then the highest load is going to be in the hours of darkness on the days with the least sunlight.
Meanwhile it's not just a problem that there is no solar output when it's dark. Sometimes renewable output is low for an extended period of time. It could be at 20% of typical for a month. Having enough batteries to last a month rather than just overnight is prohibitively expensive. So instead you'd have to build five times as much generation, which is only the same cost as nuclear because of government subsidies (which would require a much larger government budget allocation if you tried to build that much of them), and only if you're using the recent high price of nuclear that comes from building very few plants instead the lower prices that would be possible by doing it at scale.
And even using the subsidized price for renewables against the current price for nuclear, if you actually tried to build five times the capacity in renewables, the "generates the most when the market price is the lowest" thing would destroy you. The price on most days would then be zero because of huge oversupply and you'd have to recover the same total cost as current nuclear from only the days when your output is lowest.
Meanwhile if you use nuclear for what it is, i.e. baseload, and build only as much of it as you have minimum load throughout the day, it not only doesn't require any storage, it avoids the need for solar to use storage to supply power at night. Then you use solar for the incremental load during the day, to charge the batteries to use for the incremental load in the early evening and for charging electric vehicles by putting chargers in workplaces.

Comment by Gareth321 21 hours ago
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.

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.

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.

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.
Comment by moooo99 1 day ago
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.
Comment by Macha 1 day ago
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.

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.

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
Comment by phil21 1 day ago
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.

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.

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.

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.

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.

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.

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)

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.

"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.
Comment by otherme123 1 day ago
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.

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.

About 50% of the retail price of petrol in Ireland is tax (excise + carbon + VAT).

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.

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.

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.
Comment by zahlman 1 day ago
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.

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.

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.

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.

Wind is then possibly low across much of Europe, meaning Holland and Germany ramp dispatchable capacity, including German lignite.

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.

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.

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.

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?

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.

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.

Coal, with any available technology, is more polluting than any renewable energy source. Full life cycle including plant installation included.
