WATER
Hydropower is the energy that is created from water falling or flowing. 2,000 year ago, the Greeks often used water wheels for turning wheat into flour. Since then, people around the world have been using this source of energy. Hydropower plants use dams to hold back water that is then released through a turbine. The turbine’s spinning starts a generator that produces energy.
Something that is unique about hydropower is that it has the ability to store energy. It starts as the same as a regular power plant, but instead of the turbine spinning forward, it spins backwards. The turbine pumps the water to a pool, like, area that stores the water when needed. If needed, the water is released back to the turbine, spinning it forward starting the generator.
The use of water energy is very cheap and is good for the environment. It produces a small amount of heat that is not enough to harm the earth. Also, the dams built can help prevent the area from flooding.
