Electrical Power Generation

In an electric power generator, one type of energy is converted into electrical energy. Power-generating systems are simply a combination of potential or stored energy that is converted to provide kinetic energy, which, in turn, generates electrical energy for use in engines, lighting, heating, and other benefits of modern life.
