  2. Wind Energy Facts • Wind turbines can be ran by airflows • 600 kW – 5 MW is the range of power that wind turbines use • As wind speed increases power output increases • The long term technical potential of wind energy is said to be 5 times total current global energy production – offshore resources can contribute more energy • There are two types of wind turbines: - vertical axis or “egg beater” - horizontal axis or “propeller style” • Wind Power produces no greenhouse gases • Wind energy is a converted form of solar energy

  3. Advantages • U.S wind energy installations produce enough electricity on a typical day to power the equivalent of more than 6.5 million homes • By 2010, 10 million houses in the U.S, could be supported by wind power, which would prevent 100 million metric tons of CO² emissions every year. • Wind energy is cheaper than any other new electric generator except natural gas. • Over the last 20 years, wind electricity cost have gone down by more than 80% • The power plants can generate electricity for less than 5 cents/ per kilowatt-hour • Wind energy produces pollution-free electricity • Using more wind energy can help prevent global warming

  4. Disadvantages • Wind Energy has an environmental impact on erosion • There are more bird kills, because the collide with the wind turbines • There are some visual impacts, but they can be prevented by designing and spacing them the right way • In earlier designs of wind turbines, noise was an issue, but because of better engineering that has been mostly eliminated • Wind isn’t consistent • There has to be a lot of land to install the turbines

  5. Cost • Wind is the cheapest type of energy besides natural gas. • It can cost from around 5 cents/ per kwh to 6 cents/ per kwh

  6. Future Plans and Goals • It is said that wind power could provide 20% of U.S electricity • By 2010, 10 million houses in the U.S, could be supported by wind power, which would prevent 100 million metric tons of CO² emissions every year. • The U.S plans to eliminate air pollution, which will eliminate some premature deaths. • Wind power is also supposed to help reduce the chance of Global Warming

  7. A magnetically levitated wind turbine • Generates 1 gigawatt of power • a design that is being proposed by Arizona • Can provide power for less than 1 cent per hour • It can reduce construction and maintenance costs • China already has a maglev turbine that is operating today

  8. T. Boone Pickens • http://link.brightcove.com/services/player/bcpid1632654798?bctid=1653634930 • Has the worlds largest wind farm • 10 billion dollars to build • Built in Texas • The project produces up to 4 gigawatts of power • Introduced the Pickens Plan

  9. Wind Energy • In the next ten years Wind energy may be the most common type of energy used. It is cheap and it prevents air pollution. Wind energy is not very dangerous, and it can help out many Americans today.

  10. Types of Wind Turbines • Loop-wing • Helix Wind • Quiet-revolution • Selsam super turbine • Super turbine • Eggbeater • Kite turbine • Windspiral turbine • Maglev turbine • Laddermill • Offshore installation
