With AI on the horizon and each server farm using as much energy as a medium-sized city, I have no idea how they hope to meet demand otherwise, unless the plan is just some equivalent to "drill baby drill".
It’s simple, Germany isn’t going to be participating in the next industrial revolution. It will be the US vs. China. You can already see it happening with their car industry as they struggle to keep up with new technology.
Could you expand more on your car point? I thought BMW and Benz were doing great at the moment. I dunno much about Audi or VW, but Mini also seems to be doing well (which I thought was British, but one of their models has literally the same engine as my last bimmer, so I guess they were sold at some point?).
It would take a long time to build new reactors, so not sure that would help.
Germany could also do more wind, solar, tidal, geothermal (fossil fuels aside).
I'm not sure how tidal and geothermal fare in Germany
It seems that some geothermal works have caused mini-earthquakes and soil shifts in Germany and the Netherlands
It is going to take a long time and a lot of resources no matter what so maybe we should be building effective longterm solutions like nuclear instead of stopgap solar and batteries
You limit data center power demand until the AI bubble pops.
Peak Bubble - https://news.ycombinator.com/item?id=45218790 - September 2025
US Data center projects blocked or delayed amid local opposition - https://news.ycombinator.com/item?id=44097350 - May 2025
A country is not forced to have AI farms running in it. Building giant powerplant for the AI tech (possible) bubble not seems wise.
The plant will take 5 - 10 years to build, who knows what demands AI will have at that point.
SO let some countries that want to spent enormous amounts of their energy on AI do so, adn the rest can connect to those.
This is shortsighted. China routinely experiences large overcapacity in their electricity grid just to deal with the unknown unknowns of outages and other new demands. Suppose that the AI bubble burst and AI energy use is negligible, the extra capacity could be used for something else: retire your traditional coal fired furnaces for steel making and replacing them with electric arc furnaces; produce more aluminum; build more EV chargers.
Yeah, advanced geothermal is very interesting. They're taking fracking techniques and using them to get to hot rocks, which opens up geothermal to a much, much wider set of locations. Interested parties say it could provide everything we need beyond wind/solar, and seems much simpler than building out nuclear plants.

Germany has stopped actively trying to sabotage France on nuclear energy at every occasion in the EU. That’s a start.
Give you hope that at some point, they might even move on the brain dead competition policies in the energy market and we might end up with a sensible energy policy.
I’d guess Germany’s opposition to French nuclear power wasn’t just about the technology itself, but tied up with political and economic strategy. There must have been stronger political reasons behind it than simply « not liking nuclear ». I’d be curious to read something deeper on the subject and understand the reasoning behind those strategies since the Fukushima accident.
Nuclear is really unpopular with a significant part of the German electorate especially on the left. So, yes, it’s entirely political.
I guess sabotaging France by preventing it for exploiting the advantage its great strategy in energy should have afforded it is just cherry on the cake.
France is sabotaging France on nuclear.
Flamanville 3 is a complete joke and the EPR2 program is in absolute shambles.
Currently they can’t even agree on how to fund the absolutely insanely bonkers subsidies.
Now targeting investment decision in 2026… And the French government just fell because they are underwater in debt and have a spending problem which they can’t agree on how to fix.
A massive handout to the dead end nuclear industry sounds like the perfect solution!
The EU is fining France because they don’t have enough clean energy in their mix despite France having the cleanest energy in Europe because nuclear used to not count. They are also forcing the French national energy company to resell their electricity at a loss to competitor moving money which should be used to invest into the pocket of private investors. And let’s not talk about the utter stupidity of the current discussion on the dams.
Then you realise that a significant part of France new debts was due to them shielding their population for the soaring prices of electricity despite France producing cheap energy, said prices being due to Germany brain dead strategy leading to a dependence on Russian gas and the obligation to go through the European market, and you start to see the double whammy.
Well, at least, the energy market is not as bad as the ECB rules.
You do know that a large portion of the energy crisis was caused by half the French nuclear fleet being online when it was for once truly absolutely needed?
https://www.nytimes.com/2022/11/15/business/nuclear-power-fr...
I also note that you didn’t have anything to say about the EPR2 program and the absolutely insanely bonkers large subsidies needed to get it off the ground.
The historical data shows that France didn't have upwards trend in nuclear generation since early 2000s.[1] I wouldn't bet on it to change regardless of political climate.

Still no storage for nuclear waste, long construction times and expensive as hell.
Die you hear about the Söder-Challenge?
The head of the bavarian CSU want to go back to nuclear energy and comedian Marc-Uwe Kling promised to praise him if he finds and operator who is willing to build a nuclear power plant in Germany without any government subsidies.
> if he finds and operator who is willing to build a nuclear power plant in Germany without any government subsidies.
So basically, be the only energy source not subsidized? There are plenty of decent reasons to be against nuclear, and there's a discussion to be had on its price, but pointing out subsidies in the energy sector is like casting stones from your glass house.
Germany will come around when their Green ship comes aground.
Probably within the next ~5 years. The coal phaseout will happen, but only by replacing it with natural gas. It will result in the last easily achievable reduction in CO2, but it will also increase the already sky-high energy prices in Germany.
After that? There's nothing. There are no credible plans that will result in further CO2 reductions. The noises about "hydrogen" or "power to gas" will quiet rapidly once it becomes clear that they are financially not feasible.
The data does not back up this narrative: https://ourworldindata.org/grapher/share-elec-by-source?coun...
The share of electricity production that coal lost is primarily take up by wind and solar, not gas.
The devil is in the details. The easy part is now done, and further significant increases in solar/wind in Germany are not going to happen.
Renewables now dominate generation during the optimal periods, but there's nothing on the horizon for other times.
Your graph also ignores energy used for heating and for industrial processes. Their electrification is now stalled by high energy prices.
Nuclear power is clean but VERY EXPENSIVE.
Dispatble solar and wind are about 1/5 the price of new nuclear.
Funny how all the nuclear chills forget the plethora of issues that come with that tech.
- who has access to nuclear power? - what happens to nuclear reactors during war? - where does the Uranium come from? - how long does it take to build a reactor? - how many long term solutions have been developed in the more than 60 years of this technology’s existence?
Not saying nuclear doesn’t have a place, but let’s not be blind to the long list of complications that come with it.
Whatever. No one wants to invest into it anyway.
LCOE does not account for the full (system) costs. Nuclear power plants have capacity factors over 90%, while PV/Wind have less than 25%. LCOE does not account for the added costs, such as increased transmission and storage/backup costs.
It does not account for a lot of things, for example insurance.
Quote from https://www.manager-magazin.de/finanzen/versicherungen/a-761... (Google translated):
Berlin – According to a study, comprehensive insurance against the risks of nuclear power would cause electricity prices to explode. According to calculations by actuaries, the premiums to be paid could cause electricity prices to rise more than forty-fold.
"Nuclear energy is ultimately uninsurable," said insurance expert Markus Rosenbaum on Wednesday in Berlin. If an insurance company wanted to build up sufficient premiums for a nuclear power plant within 50 years, for example, the remaining operating life of a reactor, it would have to charge 72 billion euros per year for liability insurance.
The German Renewable Energy Association (BEE) commissioned the "Leipzig Insurance Forums" to conduct the calculations even before the Fukushima reactor disaster. "The true costs of nuclear power are ignored and, in the event of a serious accident, are passed on to the public," said BEE Managing Director Björn Klusmann.
Now you know the true reason why we Germans abandoned Nuclear energy :-D
LCOE refers to the price in MWh (produced electricity), so it takes capacity factor into account. Whatever electricity you produce and sell depends on your installed capacity multiplied with the capacity factor.
Similarly, you pay for the electricity you receive and this is priced as say 40$ per MWh. Obviously when you receive nothing the price is 0, you don't pay them to idle, they either produce or not. Thus when storage costs kick in you don't add the costs of both together. You either pay one or the other, not both.
You might average them out taking into consideration what their output is, but you don't stack the costs on top of each other which I often see people do.
> Germany, long a symbol of anti-nuclear politics, is beginning to shift.
err, no. it's not. industry lobby tries again and again, yes, and party officials parrot that lobbying, yes.
but no: there is no Endlager (permanent spent nuclear fuel waste site) in sight, the costs of dismantling used plants are outrageous and if it were not for nimbyism, we'd be essentially self sustaining on wind and solar within a decade.
matter of fact fossil and nuclear sponsored fud on wind and solar is the single biggest issue we face in Germany.
Atomkraft? nein, danke.
State level NIMBYism is what's happening with nuclear. The state decides we won't have that in our back yard in the case of Germany.
Fear uncertainty and doubt is the only thing blocking nuclear power.
The irony is that the fud has been spread by "environmentalists" and has only managed to keep fossil fuels around for the last 20 years greatly exacerbating our climate change predicament.
> but no: there is no Endlager (permanent nuclear waste site) in sight
The Problem in Germany is that by law the state has to build a repository, while the operators have to pay for it. The operators did pay (~24 bln EUR), but politically either NIMBY parties (such as CDU/CSU/SPD) block it, or the Greens (under Habeck) block progress so they can continue to shout "what about the waste???"
In Finland the operators can build their own repository and they did it cheap and relatively fast.
Also from an even more anti-nuclear country (austria): Kernenergie? Ja bitte!
Finland is the world's first and only such facility so far.
the law to build it is pretty universal, the world has essentially agreed to not export nuclear waste.
associating the progressive innovative green party with blocking progress is an interesting turn, there was no progress in the topic for decades, and the reason is rather that nuclear waste is like toddler art: first no one wants to take it, trying to toss it is met with loud and hefty protest, and at the end nobody knows where to take it.
don't the alps have lovely granite areas for the Finnish model?
I propose we store it in your basement. It's really not a flame war, but people that consider themselves rational argue it's no big deal, so they should be prepared to store it in their immediate vicinity. I support renewables and don't have a problem with solar panels on my roof or even a windmill in my backyard.
Finally, France will be happy after years of being pushed back on this with the drive for solar and wind turbines, which sadly all got supplemented via gas on the back that nuclear was bad.
Sadly, with electricity becoming more reliant on gas and other fossil fuels when it is not so sunny in winter, or on those cloudy days with no wind, means fossil fuel usage ends up higher than if they had stayed and expanded nuclear - instead they closed many plants(Germany a prime example, in favour of....gas).
Then the whole over-dependence on Russian gas and oil really did whammy the energy price market, not just for Europe, but with a knock-on effect across the world. One we still pay for today.
I read a lot of comments talking about „getting down the operational costs“ but i am missing someone talking about the costs of depositing the nuclear waste until it has no more risks. Am i missing something?!
Yes the cost of depositing nuclear waste is trivial, it takes a small number of large concrete structures underground in well picked locations.
The US produces about 1250 cubic meters of waste per year. For comparison the empire state building has a floor area of 208000 square meters, assuming a 3 meter floor height you could fit about 500 years worth of spent fuel inside it.
The EU may have a geopolitical interest in taking another look at nuclear. The dependance on Russian natural gas and expensive imported US natural gas is not good for their economic outlook long term. Honestly I am surprised Germany has not fired back up a couple of its plants considering its difficulties with Industrial output and competing in a world market.
In case you are in (or IP-geolocated to) the EU: https://www.arte.tv/en/videos/115068-000-A/nuclear-putin-s-d...
Clean, mostly. With future? No, it creates primary heat. Wind and solar do not.
Water power also does not, but power from damns is not clean if you want an eco-friendly power source.
Wind currently also has a bigger environment impact than solar, but is of course a source available more frequently at night [citation needed, just kidding].
And waste we need to dispose of, which no countries has long term experience in storing. Except for costly disasters in how not to intermediately store it, here in Germany.
If the very finite amount of nuclear fuel is so useful, why not make future generations happy by preserving it for them, and for now, limiting its use until we learned how to add to the initial price the full cost of long term storage, with further disasters as a learning experience for that?
Saving lives and being cost-effective in the short run might work, but every energy expert says in 50 years, nuclear will have to be phased out anyway. And fusion could provide clean, but also primary heat inducing energy. So even that will not save us.
Primary heat on this scale isn't nessisarially a bad thing. It has a very small impact on the global power balance with respect to the effect global warming.
There are also lots of uses for waste heat. Nuclear plants tend to be paired with some sort of massive hydraulic engineering project, it turns out that a lot of animals like warm water.
I am pretty sure we can figure out how to store nuclear waste if given the opportunity.
>If the very finite amount of nuclear fuel is so useful
It's not very finite. There is a ton of it. Even the vast majority of the "waste" we produce could be recycled to produce more fuel.
> No, it creates primary heat. Wind and solar do not
Luckily we do need lots of heat. District heating, process heat, thermochemical H2 production, ...
Asking because I don't know. How is enrichment governed? Say for instance if a country is only using it for energy vs defense/offense. And are there elements that can be specifically used for energy vs otherwise? Last I remember, having access to enriched uranium was grounds for a country to bomb another one.
The only way to ensure that a civil uranium enrichment program remains strictly civil is via transparency and monitoring. A country that has mastered uranium enrichment technology for fueling civil power reactors could use the same technology to produce bomb-grade uranium. It actually takes more work to enrich natural uranium into fuel for power reactors than it takes to further enrich power reactor fuel into bomb material:
https://scipython.com/blog/uranium-enrichment-and-the-separa...
> Might as well build a feature into the reactor so that it only works with <=20%
How would this help? Nuclear power plant and enrichment facility are separate entities.
You should read the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as it addresses several of those issues. Possession of highly enriched uranium isn't necessarily an act of war by itself.
https://disarmament.unoda.org/en/our-work/weapons-mass-destr...
Natural uranium on earth is currently about 0.7% U-235; civilian power reactors typically need low-enriched uranium which is 3% to 5% U-235.
The critical mass required for a weapon shrinks as enrichment increases; implosion designs would require an infinite mass at or below 5.4% enrichment (see https://en.wikipedia.org/wiki/Enriched_uranium).
Weapons-grade uranium is more like 85%+ U-235. Enrichment above around 20% is what really raises red flags.
> Enrichment above around 20% is what really raises red flags.
Which, as I understand it, is because at 20% enrichment you've already done about 70% of the work needed to get to 85%.
Modern weapons use plutonium not uranium, uranium weapons can be constructed.
All it takes is the enrichment to produce the fissile material for a weapon.
As far as I know countries have agreed to not build weapons, with the exception of those that already have them, there is an international body that monitors enrichment sites, but checks are voluntary a country can choose to not accept inspections and/or build additional secret enrichment sites.
The fissile material is not sufficient for a weapon though, as I understand there is quite a bit of science that goes into making a bomb.
Additionally, first generation weapons are large and unwieldy, i.e it takes a bomber to deploy a single weapon with a very small yield.
Miniaturization, building a weapon small and light enough to put on a missile is a significant problem that took the current powers years to get over.
But that's about it, if you can figure out how to make a small bomb of variable yield, you can make bombs small enough to fit a large backpack, and thermonuclear weapons that fit in a ballistic missile as well.
IAEA inspections verify your claimed inventory and enrichment facilities. They are trying to detect if any nuclear materials are being skimmed/diverted. As for weapons, nuclear fuel is very low enrichment (usually under 5%). Iran surpassed 60%, which has no peaceful use, so that is why it was said they were perusing weapons.
Imo that's a pretty complicated topic. On one side if you just build LWRs you just don't need very highly enriched uranium or plutonium so posession of those is a red flag. On the other side fast breeder reactors are the ones which are able to produce the least harmful waste. But fast breeders and closed fuel cycles produce and handle plutonium which in turn can be used for bad things.
Energy needs like 5% enrichment while weaponizing needs much higher and much more difficult to obtain 85% enrichment
well would being good if they specifically say thorium nuclear energy is clean energy!
Seems like the Chinese are picking up where US left off:
https://www.thecooldown.com/green-tech/thorium-molten-salt-r...
Maybe the EU can pick that up too.
In context of that really makes one think if Nazis was on to something other than toothpaste?

It's so clean that you can swim in the reactor water. You can even drink it after running it through a water filter. No waste disposal required. It's that clean.
This page and organization, WePlanet, is a rebrand of RePlanet. They advertise as a grassroots movement, but are funded by a hedge fund with a significant investment in fossil fuels [1].
I think their whole schtick is prolonging the current situation and betting on slow and expensive nuclear is a good strategy to prevent real change.
[1] https://www.theguardian.com/environment/2023/jun/30/climate-...
The problem with all kinds of "green" movements and such is that they only _demand_ solutions without being involved. That also means they might have very little idea if their premise is even valid, they just put all their energy towards organization, making signs n stuff and are very emotion-driven.
People thinking fission reactors might randomly explode like nuclear bombs Simpsons-style and so many green parties in Europe being anti-nuclear has held progress back too much. Minimal climate activism isn't bad, but they really bit hard in to the fork on this one.
Uranium mining isn't clean at all. Between Greenpeace (full of business school hacks) and lobby pressured EU courts, there's a middle ground.
Why mine uranium? Only about 4% of nuclear fuel is actually used before the fuel rods need replacement, which makes uranium highly recyclable. Given all of the “spent” fuel rods in storage, mining operations for additional uranium are unnecessary. We have enough uranium to supply our energy needs for millennia, provided we are willing to begin a recycling program.
Interestingly, the 4% actual “waste” is also quite valuable for industrial, scientific and medical purposes too. Radiation treatments for cancer, X-ray machines, etcetera all can use isotopes from it. This is not mentioning smoke detectors, betavoltaics and the numerous other useful things that can be made out of them. Deep space missions by NASA rely on betavoltaic power sources. Currently, there is a shortage, which has resulted in various missions being cancelled. Our failure to recycle “spent” nuclear fuel rods is a wasted opportunity.
Sure, now show us how to recycle spent fuel rods (and become a billionaire).
What do you mean? Modern in situ uranium mining is one of the lowest impact mining of resources we have. It's not perfectly clean, but it's pretty darn good.
>What do you mean?
I mean it's not clean
>one of the lowest impact mining of resources we have
Not the point. It's not clean, it shouldn't be called clean end of the story.
Ok, well by this definition, all human development activity is unclean. This is a perfectly valid point of view but is pretty distinct from the modern definition of clean.
Then what is clean? By that definition Solar and Wind aren't because copper and iron mines aren't clean.
Do you think rare earth minerals for batteries and photovoltaics grow on trees?
I'm totally fine with people attempting to build new fission plants. More power to them!
I just don't see it happening. They cost too much and take too long. Not holding my breath here.
Maybe Western nations will allow Chinese companies to come build their nuclear plants. That would be something.
EU is not so bad at all, in fact, it's really cool.
This is clean, until something goes catastrophically wrong.
(Which eventually it will. The more reactors, the more chances for it to happen.)
Even accounting for the times things have gone “catastrophically wrong”, nuclear is many orders of magnitude safer per unit of energy than every other energy source except solar.
https://ourworldindata.org/grapher/death-rates-from-energy-p...
Data reported by Forbes put the death rates for nuclear power in the US below all other sources of energy including solar:
https://www.forbes.com/sites/jamesconca/2012/06/10/energys-d...
The death rates are wildly different than the ones at the site you linked. I wonder what the reason is for the discrepancy.
The death rates might be a difference in units; the Forbes article is using deaths per trillion kWh, the other might be deaths per thousand/million kWh.
The difference in ranking might be down to how they model deaths from nuclear power accidents. One may be using the linear no threshold model, and the other may be using something else. We don't have an agreed upon model for how likely someone is to die as a result of exposure to X amount of radiation, which causes wide gaps in death estimates.
E.g. Chernobyl non-acute radiation death estimates range from 4,000 to 16,000, with some outliers claiming over 60,000. That's a wild swing depending on which model you use.
The nuclear industry did say that this would happen but the reality was the exact opposite:
>According to research institute Fraunhofer’s Energy Charts, the plant had a utilisation ratio of only 24% in 2024, half as much as ten years before, BR said. Also, the decommissioning of the nearby Isar 2 nuclear plant did not change the shrinking need for the coal plant, even though Bavaria’s government had repeatedly warned that implementing the nuclear phase-out as planned could make the use of more fossil power production capacity necessary.
https://theprogressplaybook.com/2025/02/19/german-state-of-b...
Both those design types were operational in the 1960s in the US but have been shut down due to lack of performance and industrial interest. New interest has started today, but let's not claim the new ones are some kind of new improved tech that evolved out of our workhorse water cooled/moderated plants.
You are incorrect fortunately.
Western designs are safe, most Soviet-era ones are/were not. It's unfortunate that nuclear power still has this stigma, as it's like saying "all cars are unsafe" while comparing the crash test ratings of a modern sedan to a 1960's chevy bel aire.
That tsunami killed 20.000+ people, and spilled massive amounts of chemicals and toxic junk to the ocean.
Yet people keep fixating over the radioactive pollution, including evicting people from their homes for truly minor amounts of radiation.
Turns out the "worst case scenario" of nuclear accidents is jackpot for nature. By clearing Fukushima from humans, nature is thriving: https://www.sciencealert.com/animals-aren-t-just-surviving-i...
The main reason is a combination of negligence by the owner of the plant and not enough enforcement of standards. The fukushima powerplant was known to have sea wall lower then required and as such was vulnerable to a tsunami (this was known for quite a long time) Combined with backup power in the basement (also against standards)
For an example of what happens to a reactor build according to safety requirements see the onagawa nuclear powerplant
I'd say a reactor in inland Europe is far from the craziest place to put one. God forbid someone were to put one in the Pacific ring of fire... oh, wait...
I believe Greenpeace leaders and activists genuinely consider themselves environmentalists. As an organization, Greenpeace is also pretty strict on declining funding that could compromise its independence.
However, it's likely that Greenpeace benefits from indirect support from the fossil fuel industry and petrostates. If you get too deep into Realpolitik, you start believing that ideologies and convictions only hinder and weaken you. Then it becomes acceptable to support groups that are ideologically opposed to you, as long as it advances your strategic interests. There have always been ways of manipulating the public sentiment, and social media has made it easier to do that without linking the manipulation back to you.
There's this weird dissonance where people don't seem to want to admit that someone championing the same cause as them can be really really dumb about it. Must be a plant, couldn't possibly be that a lot of people take stances on positions due to their emotional reaction and don't always look at the evidence first. That's just them, not *US*.
I agree that the fears are overblown, but at the same time the hype for nuclear is just weird. It's more complex, more expensive, less adjustable and more risky. Even the new hip small modular reactors are many years away.
The LCOE (Levelized Cost of Electricity) for solar with battery is already better than current solutions, and dropping. Wind and battery closely following. There is no way that nuclear technology will be able to compete on price in the foreseeable future.
If you consider the complexity of running a whole grid out of intermittent sources of energy and the long term vulnerability of the logistic chain required to produce PVs, the long term costs and risks are not so clear cut.
For China which has the mineral it probably doesn’t make sense but for Europe, nuclear is a solid alternative especially when you consider that you can probably significantly extend the life time of the already existing power plants. Even if we ultimately transition to something else, it’s better than coal and gas in the meantime.
I am totally in agreement, that nuclear plants shouldn't be shut down before fossil ones.
A decentralized grid sound way more resilient, then one with a few nuclear plants, which often have long unexpected downtimes (see France). I agree with you on the potential logistical dependencies, however that sadly applies to nearly everything right now.
How is the hype for a limitless clean energy source, something that could benefit every aspect of humanity more than any other invention in human history considered “weird”?
For something that is supposed to be clean it sure keeps making places unhabitable.
> limitless clean energy source
Like the guy you're responding to, I'm not a nuclear hater. We also have other "limitless clean energy sources" however, wind and solar.
How is nuclear going to benefit humanity in ways electrical energy hasn't already? We haven't been energy constrained in the past 10-20 years. It really doesn't seem like additional energy production is going to make that much of a difference.
> It's more complex, more expensive, less adjustable and more risky.
None of this happens to be true.
A single nuclear power plant is big and complex, but the amount of electricity it produces is so much more than renewables that this difference vastly overshadows the first one.
Last I checked, resource use and land use are at least 10x less. And of course production is actually the smaller part of the cost of electricity, transmission (the grid) is actually the bigger part (60/40). This gets several times more expensive with intermittent renewables.
Making the more expensive part of a system several times more expensive to at best save a little bit on the cheaper part seems...foolish. It's like the old Murphy's law "a $300 picture tube will blow to protect a 3¢ fuse" translated into energy policy.
And whether LCOE is actually cheaper with intermittent renewables is at best debatable. Factor in system costs and it is no contest. Intermittent renewables today generally only survive with massive subsidies both in production and deployment, with preferential treatment that allows them to pass on the costs of intermittency to the reliable producers and last not least fairly low grid penetration.
What happens when you have more than 80% intermittent renewables in a grid we could observe in Spain. Since the #Spainout, the grid operator put the grid in "safe mode", which means no more than 60% intermittent renewables. Quick quiz: if that is "safe mode", what does that make >60% intermittent renewables?
Here the Finnish environment minister:
""If we consider the [consumption] growth figures, the question isn't whether it's wind or nuclear power. We need both," Mykkänen said at a press conference on Tuesday morning.
He added that Finland's newest nuclear reactor, Olkiluoto 3, enabled the expansion of the country's wind power infrastructure. Nuclear power, he said, is needed to counterbalance output fluctuations of wind turbines."
Which brings us to adjustability: intermittent renewables are intermittent, you are completely weather-dependent and cannot follow demand at all. It is purely supply side. Or have you tried ramping up your PV output at night on demand? Good luck with that.
While no energy source is completely safe, nuclear happens to be safest one we have.
> A single nuclear power plant is big and complex, but the amount of electricity it produces is so much more than renewables that this difference vastly overshadows the first one.
It takes 10-20 years to build a new nuclear plant, if the goal is decorbanize the grid, then nuclear is to complex and slow.
> Last I checked, resource use and land use are at least 10x less.
True, but land use just isn't that important of a factor. Especially if roofs and other unused lands come into play. It just doesn't make much of a difference.
> (the grid) is actually the bigger part (60/40). This gets several times more expensive with intermittent renewables.
With the electrification of cars and so on, the grid has to be modernized no matter what.
> Intermittent renewables today generally only survive with massive subsidies both in production and deployment
Most of the time nuclear also doesn't pay for decommissioning and nuclear waste etc. by itself. At the same time a lot of renewable projects right now are also profitable without subsidize and this will apply to most in the near future. Especially when batteries become more widespread.
> What happens when you have more than 80% intermittent renewables in a grid we could observe in Spain.
The Blackout in Spain had nothing to do with renewables but happened due to a faulty substation.
> [...] Which brings us to adjustability: intermittent renewables are intermittent, you are completely weather-dependent and cannot follow demand at all. It is purely supply side. Or have you tried ramping up your PV output at night on demand? Good luck with that.
Grid scale batteries solve this problem.
There is no grid that can be sustained on solar and batteries or wind and solar and batteries or wind and solar and pumped hydro and batteries. Possibly geothermal for base load could replace nuclear and natural gas plants, combined with renewal energy and battery storage.
Why not? Grid scale batteries will allow using solar/wind throughout the day and not only peak times, eliminating the duck curve problem. This is already only a few years away.
This only leaves "Dunkelflaute" as a concern, which can be solved with either hydrogen/gas etc. production and storage during peaks in the summer for example.
Solar and battery have had immense investment to bring down that LCOE. Where can we get if we invest similarly in nuclear.
lol at wind though. that's not real.
That's only true because both solar panels and batteries are produced in China off cheap coal power.
LCOE is not a fundamental metric. EROI is and it's pretty bad for photovoltaics.
And even then it's not actually true.
First, solar and wind are massively subsidized pretty much everywhere they are deployed, in addition to the indirect subsidies they get from China subsidizing production (and internal deployments).
Second, and more importantly, LCOE is not the full cost, as you rightly point out. It leaves out system costs, and these are huge for intermittent renewables, and not constant. They rise disproportionately as the percentage of intern mitten renewables in a particular grid rises towards 100%.
Third, and related, in most countries where renewables are deployed, intermittent renewables not just do not have to carry the burden of their intermittency, they are actually allowed to pass these burdens and costs onto their reliable competitors. Which is even more insane than not accounting for intermittency.
Maybe you could argue against the actual arguments Greanpeace make against nuclear instead of making ad-hominem statements.
Relatedly, you could read what scholars like Langdon Winner say about nuclear energy (in short that they require an almost authoritarian posture in order to safely deal with nuclear fuel and nuclear waste); in contrast with solar which can be deployed at a local and decentralized scale.
The (authoritarian?) nation of Finland has already solved the problem of what to do with nuclear waste: https://en.m.wikipedia.org/wiki/Onkalo_spent_nuclear_fuel_re...
I watched a very interesting documentary about Onkalo, which happens to be on YouTube: https://www.youtube.com/watch?v=ayLxB9fV2y4
Last I read Onkalo was testing empty casks and had stored zero waste for zero years.
Bit of a rush to close the GitHub ticket eh?
True, they haven’t stored any waste yet but the facility is completed.
And depending on how you look at it, it could be 100,000 years before you know for sure if it works, so my claim that it’s a ‘solved problem’ is a bit strong. I’ll retract that and say that it’s the most promising idea for nuclear waste disposal, one that that is close to beginning operations.
>and the more strongly I suspect them to be fossil fuel industry plants.
I feel the same way as well. It would make sense for an oil rich country that feels threatened by people not buying oil (or gas) to subvert a movement like greenpeace.

The more I observe a lot of activists the more I suspect, a lot of organizations and movements are cold war era Soviet psyOps that outlived their handlers.
Greenpeace is both halves of the name.
While I agree that nuclear is green, IMO Greenpeace are correct about it not being compatible with the "peace" half: the stuff that makes working reactors is the most difficult part of making a working weapons.
This also means that during the cold war they suspected of being soviet plants.
Those suspicions and yours could both be correct for all I know.
> the stuff that makes working reactors is the most difficult part of making a working weapons
I'm unaware of this to be true. Civilian reactors are hardly-at-all-enirched uranium reactors. Creating highly enriched uranium or plutonium are completely different processes.
"Creating highly enriched uranium or plutonium are completely different processes."
Not an expert, but isn't all you basically need to do is running the centrifuges a bit longer?
Breeding plutonium is a different process than enriching uranium, sure, but with enough enriched uran you will have a nuclear bomb.
And a dirty bomb is bad enough and simple to construct as well.
You need more centrifuges, several times more, but not orders of magnitude more.
And you need nuclear reactors to make plutonium. The weapons you can make with plutonium are qualitatively different from the ones you can make with uranium.
Enrichment requires feed stock, and active reactor fuel is much higher in fissionable isotopes than the uranium with which it was fed originally. The U238 naturally breeds up into stable-ish U/Th/Pu isotopes which you can totally turn into a bomb.
Obviously there are such things as "breeder reactors" that are deliberately designed for this. But there's really no such thing as a can't-be-used-for-bombs reactor.
Also nuclear requires a powerful state to manage it safely, which has peace-related side effects.
No but every nuclear power plant requires local military defenses, and every country that expands nuclear power requires this state power even if they don’t have nuclear weapons.
There's a fun game you can play with countries that build nuclear power plants: "guess the existential threat".
In each case it's pretty obvious. Either they have nuclear weapons that share a supply chain and skills base or there is an existential threat out there.
In Poland's case you can tell when they started seeing an existential threat from when they suddenly got interested in building a plant.
I doubt it was for any particular energy policy objective, if they were Soviet funded. The soviets (or whatever name you want to give them now) are masters of finding fracture points in relatively stable western societies and exploiting them to make unstable western societies that are less effective at combating Soviet policy. See: almost the entirety of the modern political discourse.
It's not greed. They're not plants. They're just trapped in a self-reinforcing social structure that, as is common, adopt group ideological beliefs inconsistent with the real world. People are pretty good at finding ways to rationalize and internalize beliefs enforced by groups that form their social superstructure.
It's the same dynamic that gets people to earnestly and fervently believe in, say, they're infested with Body Thetans or that the local cult leader is Jesus or (as Pythagoras believed) eating beans (yes, the food) is sinful. The belief becomes a tenet of the group, a reason for its existence and a prerequisite for membership. Evaporative cooling fixes the belief by ejecting anyone who rejects it.
Greenpeace will never accept nuclear power. Opposing it is part of their core identity and anyone who disagrees leaves. Greenpeace the organization can be defeated, but it cannot be reformed.
Poland is the dirtiest coal producer in Europe but a point in its favor (for some) was that it didnt prove conclusively that you could decarbonize your electric grid without any help at all from nuclear power.
So, it didnt attract any hate or shaming from the nuclear industry's faux - environmentalist public relations arm. Unlike Germany, whom they really hate and for whom the FUD and lies was nearly constant.
(E.g. https://www.reuters.com/article/business/energy/german-nucle... remember when the nuclear industry-promised blackouts finally materialized? I dont).
Why are you implying that Germany has decarbonized their grid? Germany has a long term goal of decarbonizing the grid, but it isn’t there yet. They made the decision to keep coal plants burning and shut down their nuclear power plants. And even years later in 2025 they continue to burn coal - the most dangerous and dirty source of power ever invented.
>…The share of electricity produced with fossil fuels in Germany increased by ten percent between January and the end of June 2025, compared to the same period one year before, while power production from renewables declined by almost six percent, the country’s statistical office
>… Coal-fired power production increased 9.3 percent, while electricity production from fossil gas increased by 11.6 percent.
https://www.cleanenergywire.org/news/fossil-electricity-prod...
The direct deaths caused by burning coal are significant. I didn’t see any current estimates for those being killed downwind from Germany's reckless burning of coal, but overall the EU has a high death rate:
>…Europe, coal kills around 23,300 people per year and the estimated economic costs of the health consequences from coal burning is about US $70 billion per year, with 250,600 life years lost.
https://www.sciencedirect.com/science/article/pii/S030147972...
Never mind that all those coal plants are also contributing to climate change and are poisoning the oceans enough that many species of fish are not safe to eat. The waste problem from coal will also be a problem for future generations to deal with - not all the ash from burning coal is being deposited in people's lungs.
In 2023, I saw a stat that in 2023 about 17.0% of Germany electrical production was from burning coal. As a comparison, I believe that before the phase out of nuclear power, it generated about 25% of the electricity.
If Germany wanted to shut down nuclear power plants after they had decarbonized their grid, that would be their choice - shutting them down when you are still burning coal is almost unbelievable. I don’t think future generations will look kindly on countries who shut down a clean form of power while they still are running the most dangerous and dirty form of power generation ever created.
>Why are you implying that Germany has decarbonized their grid?
I neither said nor implied that the green transition is complete. Green transitions take decades. Germany is merely transitioning the fastest and doing it without the overpriced and risky albatross that is nuclear power.
>shutting them down when you are still burning coal is almost unbelievable
It's unbelievable that the country some people are most furious at is the one that has decarbonized at the fastest rate.
Not the country next door to it that didnt even try.
They are seemingly obsessed with what was once ~8-12% of Germany's power output, but the actual environment? Not that important.
It's bizarre.
>I neither said nor implied that the green transition is complete. Green transitions take decades.
Maybe you didn't intend too, but your words certainly implied it:
>>...it didnt prove conclusively that you could decarbonize your electric grid without any help at all from nuclear power.
Since you reference Germany later, the implication above was that Germany did prove you could decarbonize your electric grid without any help at all from nuclear power. Which might be true someday in the future, but Germany certainly hasn't decarbonized their grid yet. The one thing that Germany did "prove conclusively" is that thousands of lives were needlessly lost over the last 15 years because of bad policy.
>Germany is merely transitioning the fastest
Germany will certainly not be carbon neutral the fastest. I guess it will beat Poland though.
>Not the country next door to it that didnt even try.
You have a point - it is the responsibility of every country to decarbonize. I guess a big issue here is simply money - Poland GDP is much smaller than Germany and they have less available options. Though besides your claim, I've never heard anyone actually lauding Poland's efforts or thinking it was a good thing they are using coal.
>...They are seemingly obsessed with what was once ~8-12% of Germany's power output, but the actual environment? Not that important.
I have no idea what you are trying to say here.
Like I said, I find that those who actually want to decarbonize the grid, don't particularly care what clean technology is used and different countries will have a different mix of technologies they use. Unfortunately, there certainly do seem to be some advocates of solar/wind who would prefer to go decades (or maybe much longer) burning coal and killing people and destroying the environment when their country had the option to use a clean energy source.
It's not. Not only is it a completely negligible amount (~one 50-gallon barrel per reactor per year), it's easy to store (literally kitty litter) and can be re-enriched (renewable).
Okay, not all of this is accurate. I am not against nuclear (although in recent years it has not been very cost effective), but here are some figures with citations:
- The U.S. generates about 2,000 metric tons of spent fuel each year (from 94 reactors/97 GW) : https://www.energy.gov/ne/articles/5-fast-facts-about-spent-... . For the whole world it's 7,000 tons (375-400 GW) : https://www.iaea.org/publications/14739/status-and-trends-in...
- Storing it is easy in the short term, but unfortunately any leaks are a big deal and you have to store it basically forever, which is a challenge. If Yucca Mountain were to be restarted it's estimated storing existing and new waste through 2031 there would cost in the neighborhood of $100 billion : (warning: large PDF) https://www.gao.gov/assets/gao-21-603.pdf
- It's possible to recycle the fuel, but currently an order of magnitude more expensive than digging up more : https://www.belfercenter.org/publication/economics-reprocess...
I had no idea I was off by so much with respect to waste, thanks - that's important to know. Still seems like a fairly good trade though - 7000 tons for ~400GW.
You're definitely right about long-term storage being a concern; I think only one long-term storage facility exists right now.
I believe the cost of recycling fuel is largely because it's completely unexplored. I'm sure it'll follow a similar cost reduction path most industries share.
> it's easy to store (literally kitty litter)
I showed your comment to someone who is currently writing their PhD on how to store nuclear waste safely. I barely understood half of what they said in the following rant, but they referenced the situation of the Sellafield site several times.
I swear I'm not trolling: do you mind asking them about simply dumping it (in leaded concrete barrels etc) in the deep ocean?
https://en.wikipedia.org/wiki/Ocean_disposal_of_radioactive_... makes it seem not such a big deal
Here's one. A great read: https://www.amazon.com/Plentiful-Energy-technology-scientifi...
It's available online also: https://www.thesciencecouncil.com/pdfs/PlentifulEnergy.pdf
I read it 14 years ago or so, after the Fukushima accident. I don't think the science has changed since then, or since the 90s when this project was shut down. There continue to be so much money in coal, gas, and oil and it's from there I think most of the opposition to nuclear stems from.
Apart from fast reactors, there's also the traditional reactors and storage of spent fuel. Finland's close to opening their process facility: https://en.wikipedia.org/wiki/Onkalo_spent_nuclear_fuel_repo...
Please don't post sneering, unsubstantive comments like this on HN. If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and taking the intended spirit of the site more to heart, we'd be grateful.
I see your point but it's not really that simple in this particular case. Nuclear energy production is clean under assumption:
1. You can operate the facility with a zero critical accident over the whole lifespan of the power plant.
2. You know what to do with a nuclear waste (like keep it safely deeply buried for 10'000 years).
However, point 2) is almost irrelevant now because we already have enough depleted nuclear fuel to deal with it.
1. Only six reactors have had meltdowns, partial meltdowns, serious core damage, or fatalities.
Gen 4 reactors have gravity driven control rods, passive cooling systems, core catchers, safer fuel, and moderators.
If humans were raptured, they couldn't melt down.
2. The entire planets worth of spent nuclear fuel would fit into 15 Olympic swimming pools.
Fast breeder reactors can use almost all of the existing waste and on top of that reduce it's lifespan from 100k+ years to a few hundred.
You'd get more radiation exposure from living in Denver than you would sleeping on a cask in Miami
I'm not arguing about whether we should or shouldn't use nuclear energy. We should.
> 1. Only six reactors have had meltdowns, partial meltdowns, serious core damage, or fatalities.
If we assume that everything above INES[0] level 4 is already serious enough, then there were 11 accidents [1] and around 4484 fatalities (mostly 4000 indirect from Chernobyl but still).
> Gen 4 reactors have gravity driven control rods, passive cooling systems, core catchers, safer fuel, and moderators.
And yet, 100% safety is not achievable. But the risk is probably quite acceptable now.

Glad that the Russian funded Greens were finally defeated. In the end, the green party may have doomed us with this 50 year delay.
Article claims Germany is beginning to shift. I wouldn’t count on that. Despite having to import all of their energy aside from renewables, there is a wide-spread suspicion of nuclear here. The CDU made a lot of noise about it while they were in the opposition, but turning those closed plants back on is highly unlikely. Very costly and I’m not certain the expertise can be hired.
