Electric Vehicles

Overview

Electric vehicles are powered at least in part by an electric motor, which helps improve efficiency and reduce their carbon footprint.

While non-electric vehicles ignite an air-and-fuel mixture in pistons to turn their wheels, EVs rely on induction motors, which use electricity to rotate a magnetic field that drives the rotor, turning the wheels. EVs store electricity in a lithium-ion battery block weighing an average of 900 pounds under the vehicle.

Before the discovery of the first oil gusher in Texas in 1901 and the release of the Ford Model T in 1908 (which made gas-powered vehicles drastically more affordable and prevalent), electric cars accounted for more than a third of US automobiles and were a status symbol for the wealthy. Today, millions of EVs are sold worldwide, with most major automakers committing to significantly reducing or eliminating gas-powered vehicles over the next 20 years.
