Most power stations generate electricity using fossil

fuels. However, some power stations use a different type
of fuel – they use nuclear fuels such as uranium. These
are stores of nuclear energy. Nuclear fuels are not
burnt. Their energy is released in a nuclear reactor.

Your task is to find out more about one of the different renewable

energy resources and prepare a report or presentation to share with
the rest of the class.
You should answer these questions:

• How is the energy resource used?
• Is it used in your country?
• What energy changes are involved?
• Why is it described as renewable?

• What are its benefits and problems?

Summary
• Renewable energy resources include wind, water, solar
and biofuels.
• Renewable resources cannot be used up – they are replaced naturally.
