Wikipedia enumerates the many uses of electricity in both human technology and the natural world. Electricity provides heat and private and public lighting. Electricity is vital to many appliances, like televisions, radios, computers, refrigerators and washing machines. Even automobiles use electricity and have a battery for this purpose.
