Transcript of "Sarah and tanzania -hydroelectric power"

  1. 1. Hydroelectric energy<br />Tanzania Lowery &Sarah Krull<br />September 15, 2010<br />Earth Science<br />H. Berry <br />
  2. 2. Structure & Function<br />
  3. 3. Advantage of Hydroelectric Energy<br />Not dependent on fossil fuel such as oil, natural gas, and coal.<br />Hydroelectric generators have longer functional life than fuel fired generators.<br />Renewable - dependent on the continuous water cycle.<br />Reduced carbon emissions.<br />Global accessibility.<br />Low operation and maintenance costs.<br />
  4. 4. Disadvantages<br />They disturb natural flow of rivers.<br />Create holes beneath the dam where the water falls.<br /> Smaller modules depend on the fast flowing rivers. <br />Can impact the mobility of fish and other wild life. <br />High investment costs<br />Changes in water quality <br />
  5. 5. The Future of Hydroelectricity in the United States<br />I believe the U.S. will create more hydroelectricity dams because the U.S. wants to become less dependent on foreign oil and less oil drilling means fewer oil spills. <br />
  6. 6. The future of hydroelectricity around the World<br />I believe that the world will become more hydroelectric dependent.<br />World hydroelectricity production progressed, in the 10 years between 1995 and 2005, by 18%.<br />
