Isn't this also a barrier to building hydroelectric facilities? They're basically big dams.

Also you believe we'll be able to create massive electrolysis plants to create energy storage for solar and wind? Interesting how you're so confident in massive changes to industrial processes when solar and wind require them, but totally dismissive when other solutions do.

Regardless, metallurgy and cement just need a source of heat and unlike solar and wind which need to convert electricity to heat nuclear plants produce heat directly.
