It is called putting all your eggs in one basket. Leave out coal and this is the result. Cut CA out of the grid, and problem solved. Let them bask in their environmental heaven.
I would also suggest what has zero (pun intended) chance of success but ought to be done for the sake of the country, the Republic, and the preservation of the Constitution.
My guess is since California probably did not plan ahead and order more electricity from out of state, those who will be selling them the extra juice will make a fortune.
