Lemmy and the nuclear propaganda is so funny. France recently increased the electricity prices because nuclear energy is way more expensive than solar and they will have to increase them again because half of their plants are in severe need of repair.
It's a tricky thing, but renewables and nuclear fission plants are not two mutually exclusive things that can't coexist. The issue with renewables is that, right now, they are not consistent enough to be relied upon 24/7, and we don't have, right now, a good enough storage technology to solve the issue.
Without this, the only other option is to have renewables cover 30-50% of the production capacity, and another technology to provide a base capacity when renewables cannot be used. This can be hydro, if you have it, nuclear, gas or coal. Choose your poison.
There's some promising research in using heliostats (mirrors to direct sunlight) towards a central tower to create molten salt, allowing solar energy to be stored and released at night.
That's not just research, molten salt heliostats are in active use already.
