Wind and solar are (mostly) good from a risk/benefit analysis, and I think further investment in battery tech would make them even better. But the problem with nuclear, other than waste, is the fact that noone has tried building like a bunch of reactors that are basically the same. So the training becomes industrialized, repairs and manufacturing, over time it gets cheaper. In France, correct me if I’m wrong, they did this and it was really successful. In general the main problem with both technologies is lack of public investment, i think due to political consequences from oil companies, general bourgeois resistance to public works and investment, etc.,
