Well if France could build reactors in the 70s-90s, then Germany could have done it in 2000s, right? It's not an alien technology.

Instead they chose to pour money into wind and solar and ended up with:

* higher CO2 emissions

* higher consumer electricity prices

* all that for much higher implementation cost

The gap is massive. I think it's directly comparable: these are two neighboring EU countries, comparable in size, population and GDP. They made different choices which led to significantly different outcomes.
