On a related note, they were discussing on the radio this morning a new study that shows that EVs are actually more polluting (from a carbon standpoint) than gas engines in areas that rely on coal, while they are better than gas (on average) in areas that rely more heavily on renewables. Very efficient gas engines (hybrids, for example) apparently remain the best option most places. I'm sorry to say I live in an area that is still dominated by coal. Hopefully the president's new emissions rules start to change that.
