Hydroelectric Power
Hydroelectric PowerJeanne Stroud and Forrest StuttsWhat is it? Hydroelectric power or hydropower is an energy source that harnesses electricity from moving water.
History of HydropowerMedieval Waterwheel
Ancient Chinese Waterwheel
How much do we use hydropower?Hydroelectric power accounts for 16% of electricity generated worldwide. 7% of electricity in the United States.
AdvantagesRenewable energy sourceCan immediately respond to changes in the demand for electricity
Low operation and maintenance costsWater is not subject to market fluctuations
Advantages cont.Storage of drinking water Improves the air we breathe Helps fight climate change Clean and cheap energy that is sustainable for the futurePromotes the use of other renewable energy sources
Disadvantages High investment cost
Dependent on annual rainfallRisk of flooding land and wildlifeDisplacement of local populations
Is Hydropower efficient? Hydroelectric plants provide the most widely used source of renewable energy. Climate Change is a growing concern that calls for more cleaner energy sources. Fossil fuel dependence is ultimately inefficient. Current IssuesThree Gorges Dam
