I used to be pro-nuclear. But the war in Ukraine stopped that. One does not need to be a president of Russia to bomb a nuclear reactor. A crazy guy at top of even small country can clearly manage to destroy reactors with modern conventional weapons releasing a lot of radioactivity. Smaller reactors increase that risk exponentially simply by having more targets closer to densely populated areas.

Fusion reactors in theory can be much safer in that regard, but until they are realized and shown to work I do not see any sensible alternative for building solar or wind while keeping coal and gas power stations running.
