Hydro Power

[Jessica]

Hydro Power currently meets about 20% of the world?s electricity needs, even so, many other hydro power resources haven?t been developed yet. The force of moving water derives power which is used mainly to drive electrical generators at hydroelectric dams. Energy converted by turbines and generators is fed into the electrical grid to be used in homes, businesses, and for industrial purposes. The amount of energy produced by a hydropower installation depends on the flow of the water and on the amount of head (the height from which the water falls). Electric system output is a predictable, renewable energy electrical system, due to the stream?s flow being relatively consistent.
