Wind turbine wiki

  1. 1. And how you can get in on the action
  2. 2.  What is a wind farm? Who owns wind farms? U.S. Wind Power information Where are wind farms? How can I buy one? How much power can they produce?
  3. 3.  Wind farms are groups of wind turbines owned by a group of people on land or at sea. A wind turbine’s design depends on the location’s weather conditions.
  4. 4.  John Deere Wind Energy Duke Energy Walmart  Purchased enough wind farms from Duke Energy in Texas to power up to 15 percent of the total energy required at their 350 Texas stores BP  Has interests in 13 wind farms in seven U.S. states with two more under construction Siemens Alstom Global National Governments Sources: British Petroleum (BP) Walmart Siemens Alstom
  5. 5.  Number of States with Utility-Scale Wind Installations 2011: 38 Number of States producing over 1000 MW (1 megawatt = 1,000,000 watts) from Wind Installations: 14 U.S. Wind Resource Potential  Onshore: 10,400,000 MW  Offshore: 4,150,000 MW Top Wind Power States: 1. Texas 10,648 MW 2. Iowa 4,419 MW 3. California 4,287 MW Source: AWEA U.S. Wind Industry Annual Market Report Year Ending 2011
  6. 6.  Alstom provides and develops wind farms on- shore, and individual wind turbines for on- and off-shore use. Alstom wind turbines are found in: • Argentina • Malaysia • Australia • Netherlands • Austria • Russia • Canada • Singapore • China • South Africa • Croatia • Switzerland • Germany • Taiwan • India • Thailand • Indonesia • USA • Japan • Vietnam Source: Alstom
  7. 7.  Dovetail Solar & Wind  Wind and solar power for businesses  www.dovetailsolar.com Southwest Windpower  Wind turbines for home and businesses  www.windenergy.com Lowes  Personal wind turbines for home use  www.lowes.com Home Depot  Personal wind turbines for home use, larger selection than Lowes  www.homedepot.com Amazon  Wide range of wind turbine options, largest selection  www.amazon.com
  8. 8. Depending on the size of the turbine, variable amountsof power can be produced. Having a couple turbines is Rotor Size and Maximum Power Output slikely not enough to power an entire house. The energy Rotor Diameter Power Output (kW)produced during peak use will go towards fulfilling the (meters)current energy requirements. Any time of excess 10 25created electrical energy will flow to the energy 17 100company lowering one’s energy bill. 27 225To calculate a wind turbine’s power output use: 33 300 40 500P = Power output, kilowatts 44 600Cp = Maximum power coefficient, ranging from 0.25 to 48 7500.45, dimension less (theoretical maximum = 0.59)ρ = Air density, lb/ft3 54 1000A = Rotor swept area, ft2 or π D2/4 (D is the rotor 64 1500diameter in ft, π = 3.1416) 72 2000V = Wind speed, mphk = 0.000133 A constant to yield power in kilowatts. [i.e., 80 25001 kW = 1.340 horsepower]. Sources: Danish Wind Industry Association, American Wind Energy Association Source: smallwindtips.com
