Why should we save energy?
Energy isn't free. The grown-ups in your house pay for the all the electricity you use. So wasting energy is the same as wasting money - and we know that's not a good idea!
Wasting energy isn't good for the environment either. Most of the energy sources we depend on, like coal and natural gas, can't be replaced. This is because they are non-renewable energy sources. Once they have all been used it takes forever for them to be re-made by nature itself.
