I think the premise of the article is a bit silly - not everything is "average-able". The US is huge, and many places (like SV) do have 100% renewable energy so the electric is carbon free. This is like saying that if Portugal had a 100% clean grid that cars in Poland powered by coal plants meant that Portuguese EV's were not truly "environmental".
