* I would have dig deeper on that, but regarding the timeframe when the shutdown occurred, there wasn't a big effect on gas prices. That happened before due to the war with Ukraine and the reliance on Russian gas in general. [1] The idea once was to use cheap gas from Russia and at the same time build out renewables. The latter didn't happen, resulting in the mess Germany is right now.

* There were multiple tax reductions and I think some are in the talks now. Those were independent (and before) the nuclear shutdown.

* Probably. Nuclear should have been shutdown after gas, coal etc. I am with you on that. But the ship had already sailed long ago, before the last three plants were shut down.
