The last time any company was interested to build a nuclear reactor in Germany was in the 1970s. About thirty years before the eventual (first) ban.

We can rant all day about how stupid it was of the conservatives to re-enact the ban on nuclear power without restarting the subsidies for renewables, and lament that they thus ensured that coal power would thus have to replace more of the lost load, but that's all in the past and we can't change that.

If you think we need more nuclear power to fight CO2 emissions, you're 50 years late. That ship has sailed before most of us here were born.
