That was exactly my point.
It isn't that hard. I just gave you some back of the envelope numbers that show it's almost certainly more efficient/will result in fewer emissions.
a 22% efficient NG engine is definitely going to lose out, emissions wise, vs even coal.
Transmission efficiency is typically between 92-85%
Lithium batteries are about as close to 100% as you can get.
So say a 35% efficient coal source.
0.35*.85 = 30% Throw in some battery inefficiency and you're still walking all over a 22% NG engine.
That's a worst case electric vs a best case natural gas.
Now consider that the actual grid is a mix of more efficient sources, and it's pretty obvious that the numbers go around.
A through analysis is obviously going to differ here and there, but when you're talking 22 vs 35, it's not going to move enough that electrifying the busses loses out.
