Hmm I think what you mean is that some coal plants have been put into active maintenance. IIRC this was rather a countermeasure in case of absence of gas supplies. They are not part of the regular energy market.

Anyway, I think there is not only one way forward. Countries like France choose to use a big portion of nuclear, Germany does not. And every way has its own challenges. What is important is that energy supply should be independent of oppressor states and moving into a direction of carbon neutrality.

I really don't see that as a good progression. We want to focus on renewables because that's the most sustainable way to go. Why go back to nuclear again?

That said if you are saying that's where the industry is moving even though that's probably not the best approach, fair enough. My opinion has zero effect on the industry.

Opposed to running fossile fuels alongside renewables.

But that's literally what you're gonna have to do for 20+ years if you decide to go both ways and also build new nuclear plants. Put all your budget into renewables at once and you instantly cut down on the fossil fuel you'd otherwise burn while waiting for your reactor to go online, all while you're saving money from the cheap energy yield which you can reinvest into more renewables or storage R&D to eventually overcome the requirement to run something alongside it.

No 100% renewables is viable. You don't need anything running beside it.
