Actually, we do not need more dams, just need to add generators. For example, chatfield is IDEAL for adding some 5-10 MW worth. Likewise, we have plenty of penstock where we should put generators inside.

But, we need nuclear, and we really need to start converting old oil Wells into geothermal electricity. In particular, we have a number of sites in which we drilled down to 8-10k feet, with multiple horizontal Wells in.different directions. All that is needed is drill a single well about 1-2k deeper and then frack it back to the above semi-depleted oil field. Simply inject water and then round robin the wells so that you get the hottest steam.

And as to nukes, we need to chase CONgress to get the new SMRs online, esp on the coastal areas. Those can desalinate as well.
