Then the water turns into steam thus turning a turbine creating electricity!

2) Solar energy happens when the sun sends a positive current knocking electrons out of line so new electrons can come into line creating a system that happens very quickly, creating electricity!

3) Wind energy happens when the wind blows through a wind mill turning a tubine, creating electricty!

Part two

Hydroelectric Energy and Why We Should Use it For Our Community

Hydroelectricity. At first, a dam collects tons of water in the reservoir. Then there is a small opening in the bottom of the dam where water rushes through, making a turbine connecting to a generator spin thus creating electricity!
