20. gas Non-renewable energy is found in the form of fossil fuels. This is a type of fossil fuel.

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