How is electricity generated?
Electricity is generated in power stations. Power stations need a resource, such as fossil fuels, nuclear fuels or a renewable source.
1. In many power stations fossil fuels are burnt. The energy is used to heat water and turn it into steam.
2. The steam is forced through large fans, called turbines, making them turn around.
3. The turbines turn generators. These are large magnets inside massive coils of wire. A moving magnet inside a coil of wire creates electricity (an electric current).
4. The electricity flows along cables called the national grid after going through the transformer.
