People around the world use energy every day, and some forms of energy are being used up very quickly. But resources like energy from the sun, energy from ocean waves, and hydroelectric power do not get used up completely. These resources last and last. They are called renewable resources. Hydropower is a renewable resource that is very common. The beginning of this word, hydro, refers to water. So hydropower refers to power that comes from water.

What makes hydropower work? A dam, which looks like a tall cement wall built across a body of water, raises the level of water in an area by blocking it. This causes the water to fall over the side of the dam. The falling water pushes against a machine called a turbine. The force of the falling water makes the blades inside spin. A machine called a generator captures the power from the spinning turbines. This makes electrical energy and sends out electricity to people who need it.

Resources that last a long time are called —

• energy

• fossil fuels

• renewable resources

• hydropower
