Still, the electricity is stored in batteries in the cars, and when the batteries wear out, they can pollute the garbage dumps. Also, the electricity to run the cars has to come from somewhere. Unless you generate it with solar cells or a hydroelectric dam, there may be pollution from a generating plant that burns oil to provide the electricity to charge your electric car.
