The Power of the Wind


  • Measuring Electrical Production

    • The most valuable measure of a wind turbine is the amount of electricity in kWh (kilowatt hours) the turbine produces over the course of a year in a specific wind resource
      • If you multiply kWh/per year produced by your wind turbine by your local electricity costs per kWh, you will know how much money you are saving per year by purchasing a wind turbine
  • Converting Wind to Electricity

    • The amount of electricity (kWh) a wind turbine generates is commonly called AEP (annual energy production) or AEO (annual energy output) and is based on many important factors
    • Wind Power
      • This is the amount of power in the wind available for a turbine to capture and convert to electricity
      • The major factors in wind power are
        • Speed of the wind at a specified height
        • The density of the air
          • Temperature
          • Elevation
        • Turbulence
          • What physical obstructions such as trees and buildings or land features such as hills and valleys effect the flow of the wind
        • Turbine Tower height
        • The frequency of specific wind speeds over specific time frames
    • Rotor Size
      • Measured in square feet or square meters, the swept area is a function of the blade diameter of the wind turbine and determines how much wind power can be converted to electricity by your turbine
    • The kW Name Plate Rating Myth
      • Because each turbine model on the market incorporates a generator to produce electricity, in many cases, turbines are named, categorized and regulated by the name plate rating of their generator in watts, kilowatts or megawatts. While the generator name plate rating should determine a range within which a wind turbine may produce electricity, it is the swept area that plays the biggest role in terms of how much electricity any wind turbine will produce in a specified time frame.
    • Turbine Design and Efficiency
      • Wind power engineering has evolved substantially over the years - modern turbine designs are capturing more wind, and generating more electricity thanks to advanced design and engineering.
