"let's first agree that you CO2 emission comment was an invalid argument "
It is absolutely NOT an invalid argument, if you think climate change is a real thing it is by far THE ONLY argument that matters. And it quantitatively proves how terrible Germany's decision to shut down perfectly safe nuclear reactors was.
"renewable energy remains the most cost-competitive form of generation."
Not if you want it to be as reliable as nuclear. Again you never explained what Germany is going to use as backup when wind and solar don't produce enough.
Debating you feels like debating Tesla fanboys about Waymo. Waymo actually has hundreds of self-driving cars RIGHT NOW while Tesla keeps saying they are going to have self driving cars any day now yet they all still need a safety driver.
Nuclear energy can power entire countries with almost zero carbon energy RIGHT NOW.
