Answers to two of your questions:

What's the source?
It varies with your electric utility provider. Some are mostly hydro, others mostly natural gas, others mostly coal.
But, a battery electric vehicle running on coal generated electricity has a lower GHG footprint than the same class vehicle burning gasoline.
This is because the overall efficiency and ability to clean up at large plants is far greater than what happens at your ICE on wheels.
I understand, however, that methanol is clean and lean and efficient, I'd like to transition toward that from gasoline and diesel but not at the expense of electrics.

Are there any electric vehicles charged by our current energy production facilities that can achieve anything close to a 50% reduction in GHG emissions?
Yes, absolutely.

An all electric vehicle on most utility company mixes emits about half what it's gasoline counterpart emits. And if it happens to be all renewable energy, zero emissions.



And forget hydrogen:





Aha! shenmue Apr 2015 #1
that is another huge plus to ramping up methanol production. Methanol can be made more cheaply than Bill USA Apr 2015 #3

who said methanol would drive fracking? A separate issue which will live or die on its own. You Bill USA Apr 2015 #5
