A hybrid car is a car that is powered by two or more power sources. Usually, in addition to a petrol or diesel-powered internal combustion engine, a hybrid car also has one or more electric motors that help power the car.
Hybrid cars use the internal combustion engine to charge the electric motor's battery while driving. Brake energy and some of the energy that becomes waste heat in an ordinary car can also be used to charge the batteries that power the electric motor.
Regular hybrid cars cannot be charged by an electrical outlet. So-called plug-in hybrids, on the other hand, can.
