  1. 1. Wind Energy By Michael Rooyakkers and DeAndre Dixon Period 2 10/23/09
  2. 2. What is Wind Energy? <ul><li>Wind Energy is a renewable resource </li></ul><ul><li>Wind is created by the heat of the sun, which unevenly heats the Earth, and when this happens, hot air rises and cool air replaces it causing wind. </li></ul><ul><li>The wind is captured when it turns a turbine and creates electricity. </li></ul>
  3. 3. How Wind Energy Is Used <ul><li>The electricity that is produced is used in homes and businesses throughout the area that it surrounds. </li></ul>
  4. 4. Where it is Found <ul><li>Wind can be found in valleys, on the coast, and in mountains </li></ul><ul><li>One place where they are found is in Palm Springs, California </li></ul>
  5. 5. Advantages and Disadvantages <ul><li>Probably the biggest disadvantage is when the wind dies down and the turbines will not move </li></ul><ul><li>The advantages of wind power is that it will not run out and when the wind is extremely strong, there is a lot of electricity </li></ul>
  6. 6. Storing and Use of Wind Energy <ul><li>When the wind turns the turbines, the energy gets transferred into electrical energy. </li></ul><ul><li>The energy is commonly transferred directly into power lines and or is mixed with other electricity. </li></ul>
  7. 7. History of Wind Energy <ul><li>The history of wind energy runs back to the 11 th Century </li></ul><ul><li>People used it to produce foods </li></ul><ul><li>The earliest wind turbine runs back into the 1890's </li></ul><ul><li>During the second World War, a windmill produced 1.25 Megawatts in 30 mph winds </li></ul>
  8. 8. Economic and Environmental Impacts <ul><li>This energy is an alternative then using fossil fuels when burned in power plants. </li></ul><ul><li>Thus, helping produce less pollution and preserving more fossil fuels </li></ul><ul><li>This helps the economy by not needing as many power plants which costs a lot money to make them </li></ul><ul><li>Also, wind turbines are easier to place and cheaper to use. </li></ul>
  9. 9. The Future of Wind Energy <ul><li>Wind energy provides a cleaner option to producing energy. </li></ul><ul><li>Right now, it is rather expensive to create wind turbines, but this is the last setback for wind energy </li></ul><ul><li>There will be bigger propellers, which will harness the wind better. </li></ul><ul><li>These are going to produce more energy and electricity. </li></ul>
  10. 10. Interesting Facts <ul><li>The biggest wind turbine is located in Hawaii and stands over 200 ft. tall </li></ul><ul><li>Wind energy used to be used on a boat and it powered it down the Nile. </li></ul><ul><li>The earliest windmill was in Iran </li></ul><ul><li>An average wind of 14 mph is needed to power a turbine </li></ul>
