Welcome to the tag category page for Geothermal power!
There are many ways to make power, but most of them involve some kind of fuel. Burning fossil fuels like coal and oil is a very common way to make power, but it releases harmful air pollution. Other ways to make power include using water, wind, and the sun. These are called renewable energy sources because they're always available and won't run out. They're also much cleaner for the environment than fossil fuels.
