Don't worry about coal, electric cars are still cleaner

Green Car Reports

One of the easiest ways for electric-car drivers to get in an argument is discussing how much coal-fired electricity contributes to pollution. It shows that electric cars are cleaner—even when they do run on primarily. Now a new study by BNEF (a Bloomberg spinoff) can help give electric-car drivers some peace of mind in these arguments. emissions
