When people build dams on rivers, a large body of water collects behind the dam. The water can be released and directed over a turbine, creating electrical energy.

The power of this flowing water is called hydropower. Why is hydropower a renewable resource?

• Hydropower uses water, which is not a natural resource.

• Hydroelectricity generates electricity, which can be stored.

• Hydropower uses water, which is part of the water cycle and cannot be used up.

• Hydropower generates electricity, which can be used to help the environment.
