GLOBAL USE OFWIND TURBINESAnd how you can get in on the
action
Overview
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?
What are wind farms?
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.
Who owns wind farms? 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

U.S. Wind Power 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 MW2. Iowa 4,419 MW3. California 4,287 MW

Where are the wind farms? 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• Australia• Austria• Canada• China• Croatia• Germany• India• Indonesia• Japan• Malaysia
• Netherlands• Russia• Singapore• South Africa• Switzerland• Taiwan• Thailand• USA• Vietnam

Depending on the size of the turbine, variable amounts of power can be produced. Having a couple turbines is likely not enough to power an entire house. The energy produced during peak use will go towards fulfilling the current energy requirements. Any time of excess created electrical energy will flow to the energy company lowering one’s energy bill.To calculate a wind turbine’s power output use:
P = Power output, kilowattsCp = Maximum power coefficient, ranging from 0.25 to 0.45, dimension less (theoretical maximum = 0.59)ρ = Air density, lb/ft3
A = Rotor swept area, ft2 or π D2/4 (D is the rotor diameter in ft, π = 3.1416)V = Wind speed, mphk = 0.000133 A constant to yield power in kilowatts. [i.e., 1 kW = 1.340 horsepower].Source:
