  1. Hydroelectric Power Jonathan Connelly, Serena Cheng, Ryan Dea, Josh Suh

  2. History of Hydroelectric Power • Used by the Greeks 2000 years ago • First state in America to use hydroelectric power: Wisconsin • Roosevelt Dam (1905-1911) • Niagara Falls

  3. Politics of Hydroelectric Power • Requires government funding • Controversial issue with the placement of hydroelectric generators

  4. How Hydropower Works • Flows from the force of gravity • From steep drops • Similar to traditional coal-fired power plants

  5. How Hydropower Works cont.

  6. Turbine • Similar to those found in other plants • converts flowing water energy into mechanical energy, which then becomes electricity

  7. Physics of Hydro Power • Power = Flow x Head x Efficiency Head = difference in height between source and water output Flow = speed and volume of water • Installed capacity • Mean annual energy • Mean power output

  8. So. Cal. Production and Use • 2007: hydroelectric power comprised 14% of power produced • 400 hydroelectric power plants • Ranked third in production of hydro energy

  9. National Production • Comprised 7% of energy in 2009 • Provided 200,00-300,000 jobs • Hydropower production could double in U.S.

  10. Global Production • Leading nations: China, Brazil, Canada, U.S. • China’s production tripled • Norway: 95% of power produced by hydro power

  11. Advantages of Hydroelectric

  12. Renewability

  13. Demand & Response • Can generate more electricity at peak times by letting more water down • Pump water back up

  14. Environmental Impact • No direct CO2 emissions • The environment is affected. (primarily breeding fish)

  15. Disadvantages

  16. Cost of production • Average dam costs $3 billion • However, natural gas plants cost $20-100 million

  17. Locational Issues • Must be at a site where water naturally moves • The narrower the location, the less it costs

  18. Environmental Costs • Displaces water • Damages the surrounding areas • Building the dams never fully recover the land that was used
