More than 20% power coming from wind makes the power grid unstable because when the wind stops gas plants have to take over. And it takes hours to get gas plants up and running at full power. The northern half of new Mexico can go from running nearly 2Gw of wind to 0 in about 5 to 6 hours, 5hrs is the fastest wind shutdown I have observed, it could happen even faster and I just haven't seen it.
Sure 70% of power could come from wind, then there would have to be more even faster acting, always ready power plants to pickup the slack when wind cuts out. That means lots of thermal plants just hanging out, idling, burning fuel, paying employees to not make any power.
In theory you could have any amount of wind power if you had hydro electric power to back up the wind when it cuts out. But that's not practical anywhere. Places with lots of hydro electric tend to have mountains and elevation changes, wind likes flat open areas.
Diesel driven piston engines come on line real fast...
There's effectively 0 grid battery power in the US.
The best thing to replace coal and most of the gas with is nuclear.

Why would you use California to define the state of global power generation, grid-scale storage, and bi-directional power transfer technology, etc.?
Sunlight falls all over the contiguous 48-States, Canada, and Mexico.
Wind energy, ditto.
81% of your oil and gas wells are drilled with foreign barite, purchased from China, India, Morocco, and Mexico.
Your fossil fuels / vehicles ( generators ) require un-American: Cobalt, Platinum, Paladium, Flourspar, Rheniuum, Cerium, and Rhodium for their manufacturer / operation.
2.5-micron carbon particulate matter from diesel exhaust passes directly into the human fetus, causing spontaneous abortion.( Right to Death ).
Salmon, Idaho, the only USA source of Cobalt ,just entered the market for the 1st time in October, 2022, and it must be shipped 13,000-miles, roundtrip to Sao Paulo, Brazil for processing, on bunker fuel-burning freighters before it can be used.
The Bulletin of the Atomic Scientists have pegged the upper power density for chemical energy storage at 9-Megajoules per kilogram, making for a Tesla Model S with 4,194-miles range/ charge ( grid-scale power storage ).
If you'll pull back, and look at the bigger picture, you may find that there are already competitive technological solutions currently in the marketplace which can satisfy our energy challenges.
It's just a matter of scale.
I believe that many with SCI security clearances are sick and tired of the USA being in a position to be held ransom for strategic materials that 'don't grow in the USA.'
