California also prides itself on lack of coal fired power plants. The two largest coal fired plants in the west are in Utah, and only supply power to California, but they ain't IN California. California used to be the seventh largest economy in the world. Think about a state with an economy larger than most countries. They can do what they want. Driving west into California, you can't bring in oranges or lemons either. Trucks made before a certain date are barred at the border from entering into California. Same goes for railroad locomotives. One of the reasons Cat left the truck engine business was California's rules.
