EU court rules nuclear energy is clean energy

I’m totally fine with nuclear honestly, but I feel like I don’t understand something. No one seems to be able to give me a straight answer with proper facts that explain why we couldn’t just make a whole load more renewable energy generators instead. Sure, it might cost more, but in theory any amount of power a nuclear plant would generate could also be achieved with large amounts of renewables no?

ignoring the fact that we live in the real world where money isn't infinite: nuclear provides stable base power generation, and it does it without taking up a lot of space.

Renewables produce power intermittently, and require storage to match demand. Storage either requires non-renewable resources like lithium, or else large amounts of land. in theory yes, any amount of power could be produced by renewables, but in practice renewables require other non-infinite resources to turn the power they generate into actual usable electricity coming out of your wall socket.
