The nuclear energy thing is a lark. The German nuclear base was already old and minimal by the time those decisions were made (unless you're talking about Greens in the 90s - but they barely had any power). Fundamentally Fukushima happened and Merkel realized that the blast radius of full sized nuclear plants is too big for Germany and there's no expectation that Germany has better controls than Japan had.

Anyway, nuclear just wasn't driving big energy percentages at low prices so getting rid of it had minimal impact.

The big impact was Russian gas being severed.
