    • 3. What is Hydroelectric energy?Hydroelectric energy is the use of flowing waterto create electricity.The most common type of hydroelectric plantuses a dam on a river to store water in a reservoir.
    • 4. AdvantagesControls flooding & provides recreational activities .Simple design makes for inexpensive repairs andmaintenance costs.Renewable energy source, because the water is notdestroyed by passing through the dam.If needed, dams can be shut down instantly, where thermalplants take hours, and nuclear plants can take days!Very few breakdowns.
    • 5. DisadvantagesDisrupts natural seasonal changes in the river, andecosystems can be destroyed.Ends flooding that help to clean out the silt in rivers,causing them to clog .Studies show that the plant decay caused downstreamof major dams produces as many greenhouse gasses asmore conventional methods of producing electricity.Dams are expensive to build, and due to drought maybecome useless, or produce much less power thanoriginally planned.Dams can break in a massive flash flood.
    • 6. My Vision of the future in the US I believe that Hydroelectric Energy will become the main source of energy . 1) It’s renewable 2) Inexpensive 3) 2,000 hydroelectric power plants
    • 7. My vision of the future around the world Hydroelectric energy use will decrease greatly around the world. In 2008 the demand for hydroelectric power dropped for the fist time in 30 years. In 2009 it continued drop in Europe ,China, etc.
