How Power Grids Work
Howstuffworks “How Power Grids Work”
Electrical power is a little bit like the air you breathe: You don’t really think about it until it is missing. Power is just “there,” meeting your every need, constantly. It is only during a power failure, when you walk into a dark room and instinctively hit the useless light switch, that you realize how important power is in your daily life. You use it for heating, cooling, cooking, refrigeration, light, sound, computation, entertainment… Without it, life can get somewhat cumbersome.
Power travels from the power plant to your house through an amazing system called the power distribution grid.
