● Mains electricity is used to power larger items
that need more energy.
● It is usually produced by moving a magnet really
fast near some wires in a machine called a
generator.
● Because we use it constantly we need to keep
this magnet moving as fast as possible all the
time.
● This is what happens in a power plant.
Power plants come in many different types.
● Some methods of keeping the generator working are nonrenewable. This
means that the energy source will run out one day.
● Some methods of keeping the generator working are renewable. This means
that the energy source will run not run out, or at least will be available for a
