  3. 3. Hydroelectric Power Energy created by a heavy flowing water
  4. 4. OUR Objectives • We will be discuss about the source of Hydroelectric energy • History of hydroelectericity • We will describe “how Hydroelectric energy is produced?” • We will show Hydroelectric energy as an very useful acceptable source of energy • We will discuss where is Hydroelectricity is used
  5. 5. iNVeNtioN oF hydroeletricity
  6. 6. History of Hydroelectric Power • Nearly 2000 years ago the Greeks used water wheels to grind wheat into flour • In the 1700's, hydropower was broadly used for milling of lumber and grain and for pumping irrigation water • Appleton, Wisconsin became the first operational hydroelectric generating station in the United States, in 1882, producing 12.5 kilowatts (kW) of power
  7. 7. • The total electrical capacity generated was equivalent to 250 lights • Within the next 20 years roughly 300 hydroelectric plants were operational around the world • The invention of the hydraulic reaction turbine created the sudden expansion of hydropower • 40% of the United States' electricity was provided by hydroelectric power in the early 1900's
  8. 8. INTRODUTION • Hydroelectricity is the term referring  to electricity generated by hydropower; the  production of electrical power through the  use of the gravitational force of falling or  flowing water. It is the most widely used  form of renewable energy, Previously16%   of global electricity generation 3,427  terawatt-hours of electricity production in  2010,[1]
  9. 9. • At todays date Hydropower is produced in  150 countries, including Asia. •  China is the largest hydroelectricity  producer, with 721 terawatt-hours of  production in 2010, representing around 17  percent of domestic electricity use. There  are now three hydroelectricity plants larger  than 10 GW: the Three Gorges Dam in  China, Itaipu Dam across the  Brazil/Paraguay border, and Guri Dam in  Venezuela.
  10. 10. • The cost of hydroelectricity is compare vise  low, As it is a renewable electricity. •  The average cost of electricity from a  hydro plant larger than 10 megawatts is 3 to  5 U.S. cents per kilowatt-hour.  • We used hydro power because it becomes  our necessary to use hydro power as we  need a alternative for fossil fules • However, making dams interrupts the flow  of rivers and can harm local ecosystems,  and building large dams and reservoirs  often involves displacing people and

  12. 12. Who’s using it? • Supplies 20% of world’s  electricity and 6% of it’s  total commercial energy • 3 largest producers are Canada, U.S., and Brazil • Projected use over the  next 10 years: Canada  70%, China 10%,  U.S.10% 0% 10% 20% 30% 40% 50% 60% 70% Canada China U.S.

  15. 15. Overshot Wheel It was more efficient that breast shot wheel. Some mills using These wheels still in operation In rural areas in from 1950’s till know Miller: Mrs. Aarendale

  17. 17. How useful is it? • Moderate to high net useful energy yield • fairly low operating and maintenance costs • low pollution • rarely shut down • help control flooding • supply a regulated flow of irrigation water to lowlands below the dam
  18. 18. Compared to Others • Has moderate to high net useful energy • Solar energy and hydroelectric are the highest producers of energy besides nonrenewable resources
  19. 19. Drawbacks • Flood vast areas • destroys wildlife habitats • uproots people • keeps nutrients from being sent downstream • decreases fish harvests below the dam • keep fish from migrating upstream • kills large numbers of fish
  20. 20. HooverDam
  21. 21. Glen Canyon Dam (Utah)
  22. 22. • The largest Hydroelectric Power Plant in the world • The Yangst River in China
