“Does it count the CO2 from the power plant that charges the battery?”
Dude, click the link.
I checked the link and all I saw was the CO2 calculator. I tried working with the calculator and got no where. The article was rather brief and it did not say anything about the CO2 generated from a coal fired electric power plant necessary for the electricity needed to recharge a battery for one complete charge cycle. If you saw that information, could you please provide it?
