Transcript of "Wind Energy"

  1. 1. Wind Energy By: Camille, Emily and Emma
  2. 2. Wind/Energy <ul><li>Wind: </li></ul><ul><li>Air in natural motion, as that moving horizontally at any velocity along the earth’s surface. </li></ul><ul><li>Energy: </li></ul><ul><li>Capacity for vigorous activity; available power </li></ul>
  3. 3. Wind <ul><li>Wind is caused by the uneven heating of the earth’s surface by the sun. </li></ul><ul><li>The sun makes the </li></ul><ul><li>process possible by </li></ul><ul><li>heating the air unevenly </li></ul>
  4. 4. Wind Energy <ul><li>Today wind energy is mainly used to generate electricity. Wind is a renewable energy source because wind will blow as long as the sun shines. </li></ul>
  5. 5. Wind History <ul><li>Since ancient times, people have </li></ul><ul><li>harnessed the winds energy. </li></ul><ul><li>Examples: </li></ul><ul><li>Egyptians used the wind for sailboats 5,000 </li></ul><ul><li>years ago. </li></ul><ul><li>Pilgrims used windmills to grain corn or wheat, pump water and cut wood. It is possible windmills were used almost 4,000 years ago. </li></ul><ul><li>In the late 1920’s, Americans used small windmill to generate electricity when there was no power line. </li></ul>
  6. 6. Wind History <ul><li>In the early 1980’s, wind energy really took off again in California. California wanted renewable energy sources. California now provides more than twice as much as any other state. </li></ul><ul><li>The Persains designed some of the world’s finest windmills to power simple machines for irrigation and grinding grain. </li></ul>
  7. 7. Windmills <ul><li>Windmills are used to take the energy from the wind and use it for generating appliances. </li></ul><ul><li>Windmills blades are used to collect the wind’s kinetic energy. </li></ul><ul><li>But what if the wind isn’t blowing? </li></ul>
  8. 8. Wind Power Plants <ul><li>Wind Power plants are also known as wind farms. </li></ul><ul><li>Wind farms: </li></ul><ul><li>Clusters of wind machines used to produce </li></ul><ul><li>electricity </li></ul><ul><li>Catch: not easy to operate </li></ul><ul><li>Wind speed varies </li></ul>
  9. 9. Wind Power Today <ul><li>Today wind power is the fastest-growing </li></ul><ul><li>renewable energy source. There are so </li></ul><ul><li>many new wind machines in the USA. Wind </li></ul><ul><li>Power makes up only 1% of the energy </li></ul><ul><li>used in the USA. </li></ul>
  10. 10. The Future <ul><li>Engineers need help building better wind </li></ul><ul><li>turbines. Such as using stronger, light </li></ul><ul><li>materials. Some European countries </li></ul><ul><li>have already built turbines in ocean waters. </li></ul><ul><li>Winds are usually stronger and more </li></ul><ul><li>dependable in oceans than on land. Also, </li></ul><ul><li>it doesn’t take up land space. </li></ul>
