The Other Part of the Solution is Still Lots Cleaner!
Hates Idiots,
Fancy meeting you here.
Any modern fossil fuel electrical generation plant regardless of it's fuel and if it utilizes co-generation is approximately 50% efficient contrasted with internal combustion engines in individual vehicles which are at best 20% efficient. So even accounting for some electrical transmission loss the fossil fuel used to make electricity is twice as efficient when used to produce electricity than when used to make vehicles move.
Couple that with the fact that a brushless electrical motor is at least 80% efficient whereas an internal combustion motor is 20% efficient or 4 times the difference and here's what you have: 4 times 2 equals, an 8 times more efficient people mover.
If you have trouble believing this check the market as exemplified in this article and vehicle. The cabby says that he spends just over $1/day for electricity v.s. $8-9/day for a similar vehicle with an ICE engine. Look at that would you: 8 times difference.
And it'll be an much bigger difference as fossil fuel shortages drive the prices to the moon, and build out of renewables start delivering much cheaper electricity (by comparison) over the longer run.
