NOT quite so
Electric cars don't run on electricity, they run on the fossil fuels that fired the electricity generating plants. There are the usual losses due to inefficiency in this process, plus the losses in transmission, plus the losses in charging the batteries, plus the losses in drawing energy from the batteries, plus the energy cost of lugging the batteries around. And to make things more ridiculous, to overcome the limited mileage of the batteries, hybrids have a gasoline motor and a gas tank to lug around as well !
