America’s current fleet of gasoline-powered cars and trucks leaves us dependent on oil, contributes to air pollution problems that threaten our health, and produces large amounts of global warming pollution. “Plug-in” cars are emerging as an effective way to lower global warming emissions, oil use, and smog. The technology needed to build workable plug-in vehicles exists today, but it will take a coherent strategy and concerted action in order to take full advantage of the potential of plug-in vehicles.
