If we build one in Denmark, and it went wrong, then our entire country could end up uninhabitable. And I know the plants are very safe, but look at what’s going on in the Ukraine, or how Russia blew up the gas lines recently. Again something that is probably less of an issue within the USA.
So I think countries like the US should probably do a nuclear renaissance, while other countries should stick with renewables. I wouldn’t worry so much about the storage issue. We currently build and deploy batteries that are inside shipping containers, effectively solving our storage issues. It should be noted that “our” storage issues aren’t the same as the grids issues, ours is intended to be able to store excess power. Basically you cannot sell power when the grid is full, and currently that means solar plants dump it into nothing. The batteries allow us to store it for months. Of course we also use it to sell power at better prices, but I did say we were an investment bank.
Battery tech is only going to improve. It’s sort of ironic that Tesla was so early with some of the storage solutions that other companies actually build today, but sometimes it’s not a good idea to be a first mover I guess? The big push is largely funded by countries like Germany going for full renewables of course, and Tesla didn’t have that at the time.
