Google "Messmer Plan". France built 65 reactors in 15 years as a reaction to the 70s oil crisis, and now the majority of electricity in France comes from nuclear without any significant dependency on fossil fuels. The only thing that we're lacking is political will to change things.
reply
The French energy sector is more than 50% fossil [1]. If France decarbonizes over the next decades, it will be due to renewables, not nuclear. While the government and population have been extremely pro-nuclear for a long time, the economics just don't work out. The current plan is to barely build enough reactors to replace old ones going off-line over the next decades.

That seems to be mostly because of oil use which is coming from transportation. Electrical generation is dominated by nuclear and renewables. Electrification of transport will help, provided they don't generate the additional electricity needed by burning gas or coal...
reply
That's why I used the word electricity and not energy. It isn't perfect, but still much better than the majority if the world and even Europe. The fact that even the French themselves cannot replicate it anymore speaks volumes about the weakness of the current political system. As a counter example, the Chinese can and do.

In 2024, China produced 8 times more electricity from renewables that from nuclear [1], and the renewable share is growing much more quickly. Nuclear is as dead in China as it is elsewhere in the world.

China has a huge advantage over the majority of Europe: abundance of mostly empty land with a lot of sunlight, it's unrealistic in places like Norther Europe. But I'm not talking about nuclear alone, it was the best answer in the 70s and 80s, nowadays we need a healthy mix of nuclear, solar and wind. But above everything else we need a government willing to make significant changes and make them fast.
reply
China has a larger population density than the EU. There is more empty land in Europe.
reply
> There is more empty land in Europe.

Truly empty? Or nature reserves?

reply
Chinese population is concentrated in the East. The Western half of the country is pretty much empty. Lots of sunny semi-desertic/desertic areas, too so they do have a lot of actually empty land well suited for solar (China is more to the South compared to Europe: Beijing is about same latitude as Madrid...) and wind.

Yep. Once people experience true hardship like having to keep their house just above freezing in the winter due to the cost of energy - all of a sudden impossible things become quite possible.

The only potential issue here would be if the west had collectively hollowed out its manufacturing base so much as to make surging capacity and capability a generational thing vs. immediate.

Coasting on past success eventually brings stagnation and pain. Hopefully the pain isn’t too horrible for normal folks this time around.

And now Flamanville 3 is 7x over budget and 14 years late. Online but not commercially operational.

Their EPR2 fleet are getting an enormously large subsidy at 11 cents kWh CFD for 40 years and interest free loans. Sum freely. With the first reactor online in 2038 of everything goes to plan.

How many trillions in subsidies should we handout to new built nuclear power to ”try for real”?

Or we can just build renewables and storage which is the cheapest energy source in human history.

> Green energy isn't very useful for heating in winter.

Solar energy isn't the only 'green' energy. The wind, tides, geothermal vents, rivers etc all continue to work as well or better in winter.

Plus there's a lot of room for improvement elsewhere, like insulation.

reply
> Green energy isn’t very useful for heating in winter.

Why? Your usefulness is driven by economics. As prices have continued to fall or becomes easier to overbuild, sizing solar panels for winter needs.

reply
> Green energy isn't very useful for heating in winter.

We do manage quite well to use green energy for heating during winter in Sweden.

reply
Do we? I see plenty of complaints about high electricity prices and criticism of shutdown of nuclear reactors

Citation very much needed, or "yes it is"

Heat pumps are very common in the Nordics and can be used for almost the entire year.
reply
> Nuclear takes like 15 years to build

6-7 years. France built 40 its nuclear reactors in a decade, at 6-7 years per reactor.

Right now China is building reactors at 6-7 years per reactor.

--- start quote ---

Nearly every Chinese nuclear project that has entered service since 2010 has achieved construction in 7 years or less.

Every single conventional commercial-scale reactor project in Chinese history has achieved completion in under a decade

Since the start of 2022, China has completed an additional five domestic reactor builds, with their completion times ranging from just under five years to just over 7 years. This continues the consistent completion record of Chinese projects even despite potential disruptions from the intervening COVID-19 pandemic.

China successfully constructed six nuclear reactors in Pakistan in around 5.5-6 years each

Thats China. In Europe, this building speed isnt going to happen anytime soon. The knowledge to build nuclear at that scale isn't in the coutry/continent anymore. You'd have to reteach an entire generation of engineers.

Besides that, part of the point of switching away from oil and gas is at least some independence. Europe isnt known for its nuclear fuel supply so now you're reliant on another country again.

Yes, most solar is produced in China but its about as low maintence as it gets and there is still enough knowledge to produce in Europe.

reply
> Thats China. In Europe, this building speed isnt going to happen anytime soon.

It wasn't going to happen in China either. China also disn't have the knowledge. And yet...

You are right to point out the astonishing developments in Chinese nuclear reactors technology most people are totally oblivious of. It has been standardized, is seemingly safe and far more efficient due to Chinese technological advancements; however you may be overlooking that the ability, the capacity to do that, to do what France did by installing 56 nuclear reactors due to the last oil shock, takes an industrial capacity that does not seem to really exist anymore in Europe to the same degree. I won’t even get into why that is, because it would simply turn into a book, but suffice to say, it’s a euphemistic, polite “challenge”, so to say.

But people also forget that it still takes nuclear fuel to do any of that, which France/Europe has now also largely lost access to, due to the Niger situation along with cutting itself off from Russia/BRICS. That will at some point become an issue for France/Europe, which the “remilitarizing” EU may even make one of its first contrived America-style military adventures to “protect democracy” or some other manipulative, emotive, contrived lie by the lying Epstein, Mandelson, Brunel Class.

It sure does look like Niger really could use some democracy, don’t you? Their women can’t even show off their orifices for money on Onlyfans! Oh, they happen to have rich uranium ore, well isn’t that just an odd coincidence of doing good by sharing Our Democracy©, as decreed by the unelected EU Commission.

Fun fact: Germany blew up its nuclear energy capacity with voted approval by the current EU Commission President von der Leyen, while she was in the German government ruling coalition … she has described that her own action as a “strategic mistake”. That is who is basically the dictator of Europe, someone who makes self-described “strategic mistakes” of the highest order, multi-generational, rippling, echoing, de facto permanently consequential mistakes.

no one ever talks about how nuclear presents glaring massive military targets.

a few missiles and your vaunted "green" plants are now spreading death, mutation and radiation for hundreds or thousands of years.

even when they operate "clean" their waste storage is also growing military target.

Its not a green solution, its a kick the can down the road solution.

Green energy is super useful for heating in winter. At this point heat pumps are better than gas in almost every way unless the temperature is well below freezing. So it's just a matter of electricity which Italy and Belgium can get from the current mix of green energy (wind and even solar) and other forms (nuclear, coal, etc...)
