Should Germany should actually start a new Nuclear energy program to meet their energy needs? I'm a mere pleb, I don't know. The obvious answer, yes. I believe the United Kingdom has already started.
One of the problems with nuclear power is that everything is very slow there, it will take years, if not decades, to fully resume the European nuclear program.
Another problem is with the source of enriched uranium supplies, which is approximately 40% controlled by Russia. There are also difficulties with unenriched uranium, it simply does not exist in Europe, and Africa does not seem to have the necessary enthusiasm to be a cash cow for its former colonialists.
Germany might have believed too much in its Renewable Energy program, that they might have thought they were not coming back to Nuclear Energy. Plus can Uranium be stored? Or can Russia use their Uranium exports to punish Europe/the U.S. again?
Another problem is the dramatic drop in the level of competence of European engineers in nuclear power. France's attempt to build a nuclear power plant in Finland in the early 2000s ended in complete failure, exceeding the original budget by three times. In general, there are a number of serious difficulties for Europe in this direction. And given that the most powerful Zaporozhye NPP in Europe actually left the European energy system and moved into the Russian energy system, there are already difficulties with load balancing in Europe, because windmills and solar panels are an unstable source of electricity, energy generation at night and in the absence of wind (or on the contrary, if the wind is too strong), it can drop to zero on them.
I don’t know what is in the head of European politicians who are overly enthusiastic about the green agenda, but there is a suspicion, turning into confidence, that there is burnt porridge.
Shower thought. Black Swan = World War III?
I believe if Germany and the restof Europe is pushed enough, they might strike back and use Ukraine as the entry.
