What is Energy
Electrical energy is the energy carried by movingelectrons in an electric conductor. It cannot be seen, but it is one of our most useful forms of energy because it is relatively easy to transmit and use.
All matter consists of atoms, and every atom contains one or more electrons, which are always moving. When electrons are forced along a path in a conducting substance such as a wire, the result is energy calledelectricity.
Electrical generating plants do not create energy. They change other forms of energy into electricity. For example, power plants can convert chemical energy stored in fuels into thermal energy, which evaporates water into steam, which produces mechanical energy as it moves through turbines. The turbines spin generators, which produce electricity.

The History of Electricity
In the early 1800s, Michael Faraday discovered electromagnetic induction , which is the scientific way of saying that if he moved a magnet through a loop of wire, the wire would become electrified.
In 1882, Thomas Edison opened the first full-scale power plant in New York City. Edison's electric generator was a bigger version of Faraday's basic experiment; a big magnet rotates around a wire to produce an electric current.Today's power plants are bigger and controlled by computers, but the basic process is still the same as it was nearly 120 years ago.
