What is Hydropower
Hydro power is electricity created from the force of running water. It is less expensive than mining fossil fuels and does not contribute to the greenhouse effect. Unlike other renewable sources like the sun or wind, water can be stored which makes it a great way to create electricity.
How does it work?
Rivers, dams and waterfalls can be used to generate hydro-electricity. Hydroelectric stations are built where there is running water. The most common are located in dams, where water is stored.
