  1. 3. energy A type of renewable energy that comes from the heat of the Earth’s surface.
  2. 4. This can be seen in a wind farm and it transforms mechanical to electrical energy.
  3. 6. Energy made by vibrations.
  4. 9. Energy that is stored in objects. When this energy is released, it can do work.
  5. 11. It is an energy to power machines because it can be transformed into many different forms.
  6. 14. waste Nuclear power stations is dangerous because it releases a certain type of waste that harms both humans and the environment.
  7. 16. The sum of potential and kinetic energy that is used to do work.
  8. 17. pollution Burning of fossil fuels is bad for the environment because it contributes to global warming and causes a certain type of pollution.
  9. 18. panels Solar energy is light from the sun. It can be transformed into electrical energy using a tool.
  10. 19. This is a non-renewable energy source that was formed millions of years ago.
  11. 20. gas Non-renewable energy is found in the form of fossil fuels. This is a type of fossil fuel.

  1. 1. This energy does not pollute, but it does affect the habitats of aquatic species.
  2. 2. This is stored energy which is released when a chemical reaction takes place.
  3. 5. Energy A type of energy source that will never ran out, doesn’t cause pollution and are not harmful to the environment.
  4. 7. Energy source that can’t be replaced once used up.
  5. 8. It is produced by the sun and is very important for the biosphere.
  6. 10. The result of movement of tiny particles within an object.
  7. 12. A way to use trees, plants and rubbish to make energy.
  8. 13. Energy produced when an object moves.
  9. 15. Energy cannot be created or destroyed but it can be changed.
