Gotcha. So the conversion holds as 1 gal = 20lbs, give or take 1, or 2. Most coal plants aren't pushing 1 ton per MWH, either, but for simplicity folks often round up.

RE: 1 gal gas = 20 lbs CO2
Steve,
I'm not sure I understand you post. Equating the weight of a gallon of gasoline, at 6.5lbs, to the weight of the CO2 it can release isn't straight forward. If it were, the 3 trillion tons of CO2 in the earths atmosphere wouldn't stay suspended. How much CO2 do you claim a gallon of gas will release?

I don't want take away from conclusions folks reach on off-peak demand and how it plays positively into the economics of power plants...

This is established stuff there is no running from:
1 megawatt hour of coal power produces .6-1.0 tons of CO2. See EIA.gov
1 Volt, or Leaf, per the EPA sticker produces 2.8 miles per kilowatt hour (Ex: Volt 12.9 kwh=35 miles)
1 gallon of gas releases 20lbs of carbon when burned.

Economically, EV's should clean up because electricity, highly unlike gasoline, is priced exceedingly cheap in many areas of the US. Half the country pays under 10 cents, per kwh, where it...
