Electricity is a type of energy that can either flow from one area to another or build up in one place. Humans have invented ways of capturing other forms of energy and using them to make electricity. Many things in our homes, such as lights, are powered by electricity.
Into our homes
After electricity has been made by a power station, it travels to towns and homes along a series of underground or overground cables. The electrical cables send electricity into the plug sockets found in most buildings. This is called mains electricity.
Static electricity
Sometimes electricity energy builds up in one place. This is called static electricity. The build-up can happen when things are rubbed together, like a balloon and a jumper, which can cause them to stick together. When a build-up of electrical energy is released, a spark of electricity can sometimes be seen or felt.
Lightning
A lightning bolt is a giant spark of electricity. When rain clouds rub against the air around them, static electricity builds up. If the build-up gets big enough, the electrical energy leaps to Earth as a bolt of lightning.
