My Electricity Explanation

Most of the electricity people use comes from power stations.Inside a power station is a device called a generator. An energy source --like wind, water and coal --turns the blades of a turbine inside the generator, which spins a magnet.

The spinning magnet creates a flow of electricity.Power lines on tall towers carry the electricity from the power plant to a substation where transformers reduce the voltage (strength).

Then distribution lines carry the electricity to homes and buildings, where we use it for lights, appliances, and equipment. Distribution lines can be located overhead as shown here, or under the ground.
