As I argued, Germany's nuclear was too insignificant to really matter. It's been outstripped by renewables growth many times over since the decommissioning began. And the shortage caused by Russian gas disappearing was a lot higher than the nuclear capacity that disappeared. Sure a few extra GW extra would have been helpful. But the shortage was much higher than that. And that's before you consider gas based heating (industrial and domestic) which of course is not helped at all by nuclear and which is by far the largest use of gas.
Any price increases in surrounding countries should be blamed on the policies of those countries first, and of course the Russians. And let's face it, a lot of countries were overly dependent on Russian gas. Trusting the Russians was a big mistake. And lots of countries fell for that.
In an interconnected market, when energy gets scarce, prices go up for everyone. And Germany can afford to pay high prices and it did. A lot of countries selling energy benefited from that. Oil and gas companies did really well and made record profits. And lots of countries declined to tax that appropriately and chose to let these companies keep their profits instead of taxing it and using the revenues to help those people. Don't blame the Germans, blame your local government for that. And then blame yourself if you voted them into office. Choices have consequences. And if you didn't, blame your fellow citizens.
