  • Like you, I am also interested in wind power. I know others will also have the same interest with us due to the many benefits that we can take advantage on wind energy through this wind turbines in generating free electricity. This will mainly benefit to all of us since all of us are using electricity almost daily.

  1. 1. Wind Power By Mallory Roe
  2. 2. Why This Interests Me:
  3. 3. Why It Should Interest You <ul><li>With the threat of global warming and the rising cost of fossil fuels this eco friendly and renewable source of energy is the most rapidly growing means of electricity generation. If it hasn’t affected you yet, it probably will in the near future! </li></ul>
  4. 4. How Does Wind Energy Work?
  5. 5. What on the Inside?
  6. 6. What are the Benefits of Wind Power? <ul><li>Supply </li></ul><ul><li>Lack of Pollution </li></ul><ul><li>Production Costs </li></ul>
  7. 7. Supply <ul><li>Wind is plentiful and renewable </li></ul><ul><ul><li>Basically it’s a resource we will never run out of </li></ul></ul><ul><ul><li>Also- It’s a domestic source of energy </li></ul></ul><ul><ul><ul><li>Therefore it reduces our reliance on foreign sources of energy </li></ul></ul></ul><ul><ul><ul><li>There is an estimated 50 to 100 times more wind energy than plant biomass energy available on earth </li></ul></ul></ul>
  8. 8. Lack of Pollution <ul><li>Wind is a clean fuel source </li></ul><ul><ul><li>There are no wastes or harmful emissions generated when you use wind as a source of energy </li></ul></ul><ul><ul><ul><li>Unlike conventional fossil fuel sources- No carbon dioxide, sulfur dioxide, mercury particulates or any other type of air pollution is released </li></ul></ul></ul><ul><ul><ul><ul><li>It actually reduces toxic atmospheric and green house gases that electricity produced from fossil fuels derive </li></ul></ul></ul></ul>
  9. 9. Production Costs <ul><li>In 2004, electricity from wind energy cost one-fifth of what it did in the 1980’s and this downward trend is expected to continue as larger multi-megawatt wind turbines are being mass-produced </li></ul><ul><ul><li>Since the wind is free, the marginal cost of wind energy once a plant is constructed is very close to zero </li></ul></ul><ul><li>In 2006 the cost per unit of energy produced by wind was estimated to be roughly comparable to the cost of new generating capacity using coal and natural gas </li></ul>
  10. 10. Other Benefits of Wind Power <ul><li>Wind Turbines do not need any water to generate electricity </li></ul><ul><ul><li>Ethanol production, fossil fuel and nuclear power plants all however, must circulate or evaporate large amounts of water to produce </li></ul></ul>
  11. 11. Utilization of Wind Turbines <ul><li>At the end of 2006 wind turbines were operating in more than 36 countries with a total capacity of 79,341mega-watt of electricity. </li></ul><ul><ul><li>Europe accounted for 65% of this </li></ul></ul>
  12. 12. <ul><li>The average output of one megawatt of wind power is equivalent to the average electricity consumption of about 250 American homes. </li></ul><ul><li>Wind power has been the most rapidly growing means of electricity generation </li></ul><ul><ul><li>Capacity nearly quadrupled between 1999 and 2005 </li></ul></ul><ul><ul><li>By 2010 the World Wind Energy Association expects 160 gigawatts of capacity to be installed world wide </li></ul></ul><ul><ul><ul><li>This implies an anticipated net growth rate of more than 21% per year </li></ul></ul></ul>
  13. 13. Who is Investing in Wind Energy? <ul><li>Right now The U.S. and Europe account for 81% of wind power installations </li></ul><ul><li>Germany, Spain, India and Denmark have also made large investments in wind-generated electricity </li></ul><ul><li>Denmark’s goal is to eventually produce half of the country’s power by wind </li></ul><ul><ul><li>Currently it is just over 20%which is the highest percentage of any country yet </li></ul></ul>
  14. 14. In the United States… <ul><li>A 2006 study by the U.S. Department of Energy concluded that wind harvested in just 3 of the fifty states could provide enough electricity to power the entire nation </li></ul><ul><li>Currently U.S. has reached 12,634 megawatts of installed capacity </li></ul><ul><ul><li>(math 12,634x250) that’s 3,158,500 homes </li></ul></ul>
  15. 15. Theoretical Potential of Wind Energy <ul><li>Wind’s long-term theoretical potential is much greater than current total world energy consumption. </li></ul><ul><ul><li>The most comprehensive study to date found the potential on wind power to be over 5 times the world’s current energy use and 40 times the current electricity use. </li></ul></ul><ul><ul><ul><li>To reach this ultimate potential roughly 13% of the total global land area would have wind turbines </li></ul></ul></ul><ul><ul><ul><ul><li>That land would also be available for other uses such as farming </li></ul></ul></ul></ul>
  16. 16. So What’s the Catch? <ul><li>Electricity generated from wind power can be highly variable during different timescales from hour to hour, day to day, and season to season </li></ul><ul><ul><li>However, wind is unlikely to suffer momentary failure of large amounts of generation- which is a concern or threat with some traditional power plants </li></ul></ul><ul><ul><ul><li>In this sense, wind generation may actually be more reliable due to the distributed nature of wind turbines </li></ul></ul></ul>
  17. 17. Wind seems to match to demand rather well… Report from British Wind Energy Association
  18. 18. Other Disadvantages?
  19. 19. Counter Benefits.. <ul><li>Many states in the U.S. provide incentives, such as exemption from property taxes, mandated purchases and additional markets for “green credits” </li></ul>
  20. 20. Final Drawbacks… <ul><li>Some claim these wind turbines ruin scenic landscape.. </li></ul>
  21. 21. Would you rather look at this?
  22. 22. Conclusion <ul><li>We’ve discussed how wind energy hits the spot when searching for an alternative energy solution </li></ul><ul><li>I’ve told you how wind energy is produced </li></ul><ul><li>the many advantages and disadvantages wind energy has, </li></ul><ul><li>How it is being utilized and what countries are utilizing it </li></ul><ul><li>And the potential this source of energy has </li></ul>
