1. This is why solar power generation at great scale is important: when it's cloudy and cold in the North, it's still often sunny (even if still cold!) in the South. Calif already exports power surplus to northern States (and BC in Canada) - and has been importing hydro and nuclear power at night and at winter.
2. It's also why wind power generation is important. The winds from the West are persistent.
And beyond the USA, that combination of solar (grid and endpoint), wind (mostly onshore*) and batteries will get you a long way. Not the whole way, mind you, but certainly most of the way. Then, peaking power gen is either residual fossil fuels (if Calif., for example, keeps CH4 power gen but at 10% of the total, that's still a win) or nuclear.
I have a pov that offshore wind is poorly suited for the west coast (mostly: a short continental shelf and few deepwater ports suitable for servicing wind turbines), but well-suited to the Gulf and much of the US East Coast.
Meanwhile, a while ago, was flying from Germany to London, and flew over the North Sea. It now has this immense grid of huge wind turbines. One part - the Dogger Bank farm will have 8GW output; but the whole area is being set up for TW-scale power generation.
