My Power Systems course in college back in 2014 used Germany as an example of how not to handle energy policy due to the brain-dead decision to get rid of perfectly fine and functional nuclear plants. The professor also had us produce high quality white papers and present them to the class, and receive mock peer reviews on our work showing how terrible renewables are as a "solution" compared. That wasn't his stated goal, but it was the conclusion that 107 out of 107 people in the class independently came to after a review of the relevant academic research. The only sustainable long-term solution for baseload is nuclear fission for at least the next 50-60 years barring any massive breakthroughs in nuclear fusion. Every single other option is a massive disaster ecologically and economically.
