In the foreseeable future, nukes will be mothballed long short of their design life just because nobody will want to pay enough for their power to enable continuing to operate them. Geothermal might suffer the same fate.
When a nuke is mothballed early, every kWh it ever produced will suddenly be found to have cost much more than had previously been reckoned.
At the moment, renewables still can't compete on pricing with 70s nuclear designs...
b) are you aware that half of the nuclear fleet in France isn't online?

> It's clean, it's energy dense, and we can make a lot of it. France gets most of it's energy from Nuclear plants.
It's not clean, since the nuclear industry is also polluting the environment. It's not safe, since there is a risk of nuclear weapons, it's also limited (for example one needs water for the production of nuclear electricity - which in dry summers - like right now - can be a problem).
Worst:
Parts of the nuclear energy production is largely unsolved (nuclear waste storage, clean reprocessing, ...).
It's expensive, needs lots of government money and creates huge centralized structures.
Had this money been spent on the nuclear grid, the gris would be in a much better state now.

With more than half of the French nuclear fleet offline, nuclear in this energy crisis is just only contributing to the problems.
