The argument here is that a country that keeps talking about green energy, ecology and renewables for decades is now using much less ecological methods of power generation than nuclear, and they keep badmouthing nuclear too.

Doesn't matter at all. Germany is exporting tons of underpriced (or even negatively priced) electricity in peak season - when everybody has more than enough of their own, so people are using it only to mine Bitcoin and other non essential usecases - and then there would be a blackout off-season if it wasn't for neighboring nuclear power plants, gas and coal. Very weird for a country that has its mouth full with greenness and renewability.

Is this really what German press is reporting? What a gross lie. The "overheating" is neither due to the reactor (simply it getting hot naturally) nor actively threatening to the reactor: they are just stopped to avoid making the situation slightly worse. Temperature difference at the output of a nuclear plant is barely a degree.

Actually Germans say that a lot and try to enforce it through the EU. They never found support for a complete ban but they're thwarting progress as much as they can.

And then you have the Austrians who try to cancel our nuclear power plants directly through activism, etc.
