What is Hydroelectricity?

Hydroelectric energy comes from moving water on water wheels that have been around for hundreds of years and haved been used to grind grain and run machinery.

Hydroelectric energy works like this,water pushes against the blades of a turbine to spin a generator that makes electricity.However hydroprower facillities can change the water temperature and the river's flow which might harm aquatic animals.However,making electricity this way does NOT release pollution into the air or give off toxic waste.Water is reterned to the rivers,and the water cycle makes this a renewable resourse.That is why hydroelectricity is the best alternative energy source.
