Revisionism it is not. It was Schröder’s administration that shut down Germany’s nuclear power plants.

Where is the peace movement and so-called environmentalism rooted?

Pro-nuclear is pro-environment.

The alternatives are fossil fuels and renewables, which are both extremely anti-environment: water power require large artificial reservoirs and create flood risks, wind power kills/drives away wildlife and is almost useless without efficient large—scale energy storage and other methods of power generation, while solar also requires storage and other power generation but also requires mining of rare earth metals.

Of course we could just stop all of our industries to save power. No more production, no more consumption, no more pollution.
