Electricity for powering our homes is made at power stations. A power station contains large machines called turbines, which are turned very quickly. Power stations need large amounts of energy to turn the turbines.
Some use heat energy produced from burning gas. Others use hydro (moving water) or wind energy.
The spinning turbine causes large magnets to turn within wire coils – these are the generators. The moving magnets within the coils of wire cause the electrons to move within the coils of wire. This creates electricity.
Steam turbine generators, gas turbine generators, diesel engine generators and alternate energy systems all operate on the same principle – magnets + copper wire + motion = electrical current. The electricity produced is the same, regardless of the source.
