Really good green aware site.
Summary:
-The CO2 from electricity varies depending on where you live.
-Gives the average CO2 from gas, hybrid and electric vehicles in the area
-Gives specific details for your model of car in your area.
Buffalo has advantages, they are using Niagara Falls vs Georgia which is using dirty coal I assume (sorry no such thing as clean coal evil marketing people).
Georgia (your link)"
electricity = CO2 per mile = 186g
Clarity per mile = 201g
For Buffalo:
electricity CO2 per mile = 54g!
Clarity per mile 108g
New York electricity CO2 per mile = 108g
L.A. electricity CO2 per mile = 94g
The Rant:
Before anyone gets the impression that CO2 is the only pollutant or
that moving that 3000lb car to the local shop has less of an impact than cycling a 50lb bike or even walking think again. There is a lot of bad math and bad logic out there.
