So, petroleum = transportation. Electrification at least shifts that to other sources. It seems this is where the meat is today in the US.
That 21% from coal is large enough to merit effort to reduce/eliminate, and I think we could do that in 10-15 years plausibly. Nuclear would be the most parallel generating option to coal in terms of base load, but other than the two new power reactors in GA, that looks like a done deal, and closures of older nuke plants is likely going to make this a negative. That leaves NG, which reduces GHG by a third versus coal, and wind/solar, which unfortunately are intermittent sources, not ideal for base load without storage.
So, let's imagine with some effort/expense, the US drives coal to 1% by 2035, and at least personal vehicles by then are half EVs. Can wind and solar along make up for the loss of coal? Not really, the math doesn't work, and converting automobiles to half EVs puts additional demand on the grid, mostly at night where solar is zero.
See why there is no plan?
