And how much of CA power, which BTW powers those electric cars, comes from out of state? That way they can claim to be environmentally friendly.
A lot.
Then factor in the transmission losses, 50%, and it becomes stupidity.
California passed a massive many, many billion$ bond issue still being paid for, to remove dams in the state.
Forty years later, they passed another massive many many billion$ bond issue to "improve" water supply management in the state for the benefit of... bugs, bunnies, junk fish and wacky, ignorant "greenies."
Meanwhile the government and management by the stupid, created the current man-made drought, and is killing more billions of useful fish, insects, bunnies, crops and trees and, soon, perhaps, people than anyone could imagine.
