"Ford's EcoBoost cars are powered by gasoline, which is still eco-unfriendly." And so are batteries, unless they are charged by the sun, and the entire production and shipment of all materials required to make those batteries was powered by the sun. Battery powered cars probably cause more pollution than gas powered cars since the raw materials to make the batteries are mined in africa or china and shipped on a boat ( that uses more gasoline than will ever be saved by using batteries) to another continent where the batteries are assembled and put on another boat and shipped to the U.S. where they are installed in cars that make hippies think they are protecting the environment.
