Had we done more 10 years ago we would have been better of. The second best time to start is now.
Then why all the anti-coal mining diktats coming down from Brussels?
Brussels is trying to reduce "tiny" to zero, because of this: https://en.wikipedia.org/wiki/Tragedy_of_the_commons
China, like Brussels, is trying to reduce coal for similar reasons. They don't like the air pollution health hazard (fully believable), and they say they don't like global warming (somewhat believable).
Renewables deployment is happening fast. Grid upgrades are not. Batteries .. it depends.
Even nuclear darling France has set solar records: https://www.pv-magazine.com/2026/04/15/france-germany-set-da...
(We used to build it at a fraction of the cost and less than half of the time that we do with our modern fuckups and fuel can come from just about anywhere if need be. It might be a lot more expensive than the stuff kazachstan and still be a fraction of the cost.)
I think ideally we would've done both to press the cost of nuclear down and given the fact that the renewables rollout turned out to be a lot lot more expensive than proponents claimed it would be whilst still tying us up into gass to cover winter.
The problem in the EU is not renewables, it's the same problem that Democratic states in the US face. Regulations and permitting hurdles that block private renewable energy developers.
