All-electric vehicles (EVs) run on electricity only and are propelled by one or more electric motors powered by rechargeable the U.S. Department of Energy (DOE), EVs convert more than 77 percent of the electrical energy from the grid to power at the wheels. The agency’s website states that, in contrast, conventional gasoline vehicles convert about 12 percent to 30 percent of the energy stored in gasoline to power at the wheels. According to a study released last year by the Union of Concerned Scientists (UCS) an EV emits, on average, about half as much carbon dioxide as a gas-burning vehicle.
