Tesla electric car

An electric vehicle is an automobile that uses an electric motor for propulsion, in place of the more common propulsion method, the internal combustion engine.  Electric vehicles include both passenger cars and light trucks.

Electric cars are usually powered by onboard battery packs, and are referred to as battery electric vehicles (BEVs).   Although electric cars often give good acceleration and have a generally acceptable top speed, the poorer energy capacity of batteries compared to that of fossil fuels means that electric cars have a comparatively poorer range between charges, and recharging can take significant lengths of time.   However, for everyday, commuter, and local delivery uses, electric vehicles are very practical forms of transportation and can be inexpensively recharged overnight.  Other energy storage methods that may give more range or faster recharges are areas of ongoing research.

Electric vehicles have the potential of significantly reducing city pollution by having zero tail pipe emissions.  Vehicle greenhouse gas savings depend on how the electricity is generated.  With the current U.S. energy mix, using an electric car would result in a 30% reduction in carbon dioxide emissions.

Electric vehicless are expected to have a major impact in the auto industry, given their advantages in city pollution reduction, less dependence on oil, and the expected rise in gasoline prices.
