  2. What is it? • Hydroelectric power or hydropower is an energy source that harnesses electricity from moving water.

  3. History of Hydropower • Medieval Waterwheel • Ancient Chinese Waterwheel

  4. How much do we use hydropower? • Hydroelectric power accounts for 16% of electricity generated worldwide. • 7% of electricity in the United States.

  5. Advantages • Renewable energy source • Can immediately respond to changes in the demand for electricity • Low operation and maintenance costs • Water is not subject to market fluctuations

  6. Advantages cont. • Storage of drinking water • Improves the air we breathe • Helps fight climate change • Clean and cheap energy that is sustainable for the future • Promotes the use of other renewable energy sources

  7. Disadvantages • High investment cost • Dependent on annual rainfall • Risk of flooding land and wildlife • Displacement of local populations

  8. 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.

  9. Current Issues • Three Gorges Dam • Colorado River

  10. The Future of Hydropower • Conversion of dormant dams to hydroelectricity. • Low-head hydropower systems.
