Why aren’t there more hydroelectric dams?

Doesn’t it make sense to use solar to pump sea water into man made reservoirs in hot countries, and in cold/wet countries use wind and natural rain to fill reservoirs?

As a layman it seems infinitely better than nuclear or battery storage.

I’ll assume there’s a cost element here too. The cost of building the pump infrastructure will always be used as an argument against it, no matter if it’s cheap/ efficient to run afterwards. Yay conservative politics!
