Plug-in electric vehicles (also called EVs) are cars that are powered by an electric motor instead of gasoline or diesel fuel. This means they don't cause pollution like regular cars do. In the United States, there are special plug-in electric vehicles that you can buy to reduce your emissions and get you from place to place without burning fuel. These cars are very efficient, as they use energy from batteries to power the motor, which creates electricity that can be used to go places. They can be powered by plugging them into a special charger or even using solar energy. They also often have savings on taxes and other incentives to encourage people to purchase them.
