Not without major improvements in battery tech or many massive public works projects like damns with pumps.

Or massive public works projects like nuclear reactors.

But yeah, obviously dams and deep wells with pumps are orders of magnitude less expensive than nuclear reactors. So that's likely where the money will go.

But it's ALL gonna be pricey. Only thing that isn't quite as pricey are the fossil fuels. Very little stomach for future development on those however.

Last I heard, that San Onofre upgrade didn't go so well. Who's paying for that, again?
