Electricity Electricity is a form of energy. That's because we can use electricity to do things for us, like run machines and computers. Electricity also can be transformed into other types of energy such as heat or light and is used to heat our homes, light our cities and towns and power the computer you are using.
Electricity is the type of energy that is invisible.
It's made of moving electrons that are so small and move so fast that we can not see them. The electricity that GPU provides travels through the wires you see on tall poles and towers around your town or city. Sometimes they go down in a fenced-off area that is full of large metal boxes, lots of electrical wires, equipment and other stuff. These areas are called substations, and they change how powerful the electricity is before it gets to your home.
