Washington state is powered by the dams on the Columbia River. You cannot get much “greener” than that. I can’t imagine we get a single watt of energy from coal.
You gotta love it when these politicians enact regulations that are irrelevant and then try to claim they’ve accomplished something wonderful.
And, IIRC, they do not consider hydro power to be "green" and "renewable" and thus not eligible for kickbacks and subsidies....their lunacy is breathtaking to behold.
