I think the issue is batteries, which are expensive and require rare earth metals which often have environmentally costly acquisition methods. Perhaps an optimal solution would be a baseline of nuclear power, and then enough renewables to meet peaks in demand. That way we have plenty of stable energy while minimizing nuclear risks.
When you get into power say a whole large city the batteries cost more then the solar panels. Especially in more polar places like Juno Alaska where you need to store a surplus of power for months. plus batteries degrade over time so they would have to be replaced. That's part of the reason why ion flow batteries are being researched, you can just drain them and replace the fluid*.
I didn't know about those. I'll have to look more into it. Thanks!
