Cause and effect
Every time we use energy it has many effects. Turning on a light helps us to see better (an obvious effect!) and adds a few pence to the electricity bill. But these two things aren't the only effects...
If you leave a light on longer than you need it, you use more electricity than you need. In order to generate this electricity, more fuel will have been used in the power station than was needed. If the electricity comes from a power station using fossil fuels, you will be using up a non-renewable energy source faster than necessary. Also the more energy is used, the more emissions (chemicals that go into the air) there are... so you can see the effect wasting energy has!
Try to make the correct decisions to reduce the amount of energy used and help to keep pollution levels down. As you answer the questions, watch the cloud to see how polluted or clean you are making it!
