Electricity is a form of energy coming from the flow of electrons. All matter in the universe is made up of atoms, and an atom has a centre, called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons and is surrounded by negatively charged particles called electrons. The negative charge of an electron is equal to the positive charge of a proton, and the number of electrons in an atom is usually equal to the number of protons. When the balancing force between protons and electrons is upset by an outside force, an atom may gain or lose an electron. When electrons are "lost" from an atom, the free movement of these electrons creates an electric current.

How do you make electricity?
An electricity generator converts mechanical energy into electrical energy. The process is based on the relationship between magnetism and electricity. When a magnet moves across the surface of a conductor, often a tightly wound reel of copper wire, an electric current occurs in the conductor. Within the workings of a wind, hydro or conventional turbine, the conductor remains stationary while the energy embodied in the wind, water or steam drives the turbine which rotates the magnet around the conductor creating an electrical current.
