Since we didn't have "no electricity for some months" in this one-off, and, as I explained elsewhere, had optionality, not quite sure how you extrapolate from an event not happening to an event happening every few decades.

Gosh, so we're not ever going to invest sufficiently in battery tech for that to ever work. Glad you cleared that up for us.

But to be clear, it wasn't some random "human nature" that caused the underinvestment. It was official government policy, and that government policy has now been changed.

The renewables mafia that is still in control in Germany was also in control in France. That has been taken care of, mostly by being exposed to the harsh light of Reality™.

The law that mandated reduction and forbade expansion of nuclear was repealed March 2023. They are now expanding capacity, build first 6 and then an additional 8 simplified EPR2 reactors.

And there was one more reason for the lull in investment: France did the initial expansion under the Messmer Plan far too quickly. They nuclearized their grid in just 15 years.

Which sounds great, and of course completely puts the lie to those who claim that nuclear is "too slow". But there is a problem: these nuclear plants are not just quick to build, they also last pretty much forever, at least 60 years, many if not most are being extended to 80 years and the experts say there's no reason not to go to 100.

If you have built all the nuclear power plants you need in 15 years and they last 100 years, you have nothing to build for 85 years (or 65 / 45 years if you assume 80/60 year lifespans).

That's a problem, because your nuclear industry will wither and die in that time.

Which it pretty much did.
