Germany's exit from nuclear power was decided way back in the early 2010s. When the pipeline was destroyed the last three remaining plants were overdue for maintenance, didn't have any more fuel and also no one to run the plant for significantly longer. They extended the shutdown until spring and that was it. Stop spreading the lie, that this was some kind of rushed decision or that it could have been prolonged much further.
Building new ones isnt economical and also wouldn't produce any electricity until the late 2030s
If the exit was a mistake 15 years ago can be debated, but the discussion is worthless now, no matter how often this gets pushed by the party that fucked up the buildup of renewable alternatives in the 16 years they were in power

We didn't this is misinformation spread in USA. Yes we shut down nuclear plants (but the laws fasing out nuclear were made over a decade ago because we still haven't found a solution for the waste, this was all looong before nordstream) and our investments in renewable are behind, but none is planning on going back to coal (except some crazy right wing fascists who are not in political power)

For the most part we are investing in gas heavily at the moment, which is fucking stupid in our climate situation, but the fracking gas from the USA with very competitive prices and lot of political hegemony from USA drive the government to do it anyway.
