Where does electricity come from?

Electricity runs the TVs, air-conditioners, and other devices in our homes. Have you ever wondered where electricity comes from? Electricity actually comes from power stations far away from our homes. Electricity travels along very long power lines to reach our homes. There are different kinds of power stations that make electricity. For example, thermal power stations use heat energy to make electricity. Hydroelectric power stations use water power to make electricity.

The electricity made at power stations is very powerful. So the electricity’s strength is adjusted at substations before it reaches your home. The strength is lowered to a safe level of between 100 and 240 volts by the time it reaches your home.
