2hrly gs ch p wind energy

  1. 1. WIND ENERGY
  2. 2. Wind Energy A wind farm requires roughly 17 acres of land to produce 1 megawatt of electricity.
  3. 3. Wind Turbine Basics • Wind power is the fastest-growing source of renewable energy • Basic principle is the conversion of the kinetic energy of moving air into electrical energy • Use large, specially shaped blades to "catch" moving air • The wind causes the blades to rotate • Their motion spins an attached electrical generator, producing electricity
  4. 4. Cont… • the faster the wind is blowing • the more energy is transferred to the blades • and generator and converted into electrical power
  5. 5. TYPES
  6. 6. Types • Horizontal wind turbine • Vertical wind turbine
  7. 7. Types: horizontal • the blades rotate on an axis that is parallel to the ground • fixed at the top of a support tower • three-blade design seen at large-scale wind farms uses the horizontal-axis design
  8. 8. Types: Vertical • Vertical-axis turbines fix the blades to the sides of a pole running perpendicular to the ground • with the electrical generator placed at the support base • The blades can be placed at any desired height on the pole
  9. 9. CAPACITY
  10. 10. Capacity • A single wind turbine can be small enough to provide partial power to a single home • large enough to power a small town • The larger the rotor, the more wind • and therefore energy is captured by the assembly • residential turbines are rated for a maximum capacity below 30 kilowatts • the largest turbines can generate almost five megawatts
  11. 11. PROS & CONS
  12. 12. Pros: • do not require the burning of fuel to operate and generate • Landowners can also receive rent payments • this can prove to be a valuable year-round supplement to a farmer's income • excess power can also sell to the power company.
  13. 13. Cons: • an inadequate energy source to fulfill requirements • Residents may be bothered by turbines' noise • horizontal-axis rotating blades pose an inherent threat to birds
  14. 14. ARTICLE How to choose a wind turbine
  15. 15. Introduction • Wind is an enormously potent source of clean energy • the wind resources in the Rocky Mountain and Great Plains regions • potentially meet up to 25 percent of the power needs of state • Wind turbines aren't just for farmers • a home wind energy system can be relatively unobtrusive
  16. 16. STEP 1: • to ensure you're allowed to install a wind turbine on your property. • Be sure to get a full rundown on height restrictions. • make sure you check with your homeowners association to avoid complaints from your neighbors
  17. 17. STEP 2: • Conduct an energy audit of your house • as well as where your home may be wasting energy • Add up the watts you use for all your energy needs on a monthly basis • consider whether you're over-consuming energy by using brighter light bulbs, an old heating system or a higher thermostat setting than necessary, for instance.
  18. 18. STEP 3: • Reducing your consumption may allow you to install a less expensive and smaller wind energy system.
  19. 19. STEP 4 • Decide where you'll install your turbine and how it will be mounted • Avoid placing the turbine on your rooftop • Determine the typical direction of wind at your location • and locate a spot upwind from buildings and trees to ensure maximum wind flow • Your turbine will also need to be at least 30 feet above any wind barriers sitting within 300 feet • These location specifics will help to determine the size of your turbine.
  20. 20. STEP 5 • Contact a nearby airport, weather station or university to learn the average wind speed in your area • Keep in mind that wind speed increases with the height of the tower as well • consider whether wind may slow or speed up in your specific location • AEO = 0.01328 x D [to the second power] x V [to the third power], • Complete this equation for several rotor sizes to determine which may work best.
  21. 21. STEP 6 • Ask the dealer to calculate how each model would perform in your specific location • confirm they have at least a five-year warranty and strong testimonials • Also, make sure they come with all necessary component parts • so they'll be ready to install and use.
