We can use renewable and non-renewable energy sources to make electricity.

Most of our electricity comes from power stations that use fossil fuels like coal, oil and gas. We call them non-renewable sources because they will eventually run out. Unfortunately, burning fossil fuels produces lots of greenhouse gases which cause global warming.

We also use renewable energy sources like the sun, wind and water to make electricity. We can use them again and again because they cannot run out. They do not produce greenhouse gases so they are much less harmful to the environment.
