Pumped hydro and hot sand batteries should be enough if we get our act together and actually commit to something. There’s also no reason solar from Spain or Morocco couldn’t be wired in at some point. Obviously we currently have a chicken and egg situation where it’s not worth building the X times our peak need in renewables without the storage and not worth building the storage when renewables are a fraction rather than a multiple of our current supply.

Well I’m pretty sure Morocco becoming as wealthy as Saudi would make it stable enough, one way or another.
