a nuclear site would never be cheaper than solar energy. I mean in the next 20-40 years it might have been cheaper. unfortunatly the site needs to be cleaned up in a process that costs multiple billions of euro and the storage for the factory is still not ready for the next thousands of years and is also really costly in germany.

in germany solar energy has two problems:

- trash (there is no long term storage and there probably will never be one that can sustain 1000+ years)

- cleanup of land (germany is small and has a lot of people we need to use our space without wasting it)
