A tower lifts the blades high in the air where the wind is stronger.

However, the turbine is only one part of the system.

Very small turbines will not be able to produce much power, no matter how efficient.Ī wind turbine works by catching the energy in the wind, using it to turn blades, and converting the energy to electricity through a generator in the part of the turbine called a nacelle. The bigger the blades of the turbine (swept area), the more energy it will be able to capture.This means that small increases in wind speed will dramatically increase power output. Siting your turbine in an area where there is good wind is the most important consideration since power increases with velocity as a cubed function.Practical takeaways from this equation are:

Power = 0.5 x Swept Area x Air Density x wiind Velocity 3

Wind energy generates power in accordance with this equation: This allows you to avoid unpredictable future costs of other fuels by paying for wind energy upfront. While the cost of a wind turbine is steep, the wind energy system will not require further electrical purchases for approximately 20 years. You also need to do enough research to learn whether a turbine will pay for itself quickly enough to meet your financial requirements. You also need to make sure your local zoning codes or covenants allow wind turbines and the fairly tall towers that allow them to catch enough wind to make electricity. Department of Energy has more information on siting turbines, and the American Wind Energy Association Winds on your site should be at least class 2 (annual wind speeds averaging 9.8 to11.5 mph at 50 meters above ground level) to be suitable for wind generation. A system that would offset most of an average home’s electricity use (10,000 kwh/year) will cost roughly $50,000 before incentives.Ī faster method is to look up wind data from the Colorado wind resource map and the anemometer loan program. A rough range is $4,000 to $8,000 per rated kilowatt. The cost of residential wind turbines varies depending on how much power they can produce and other factors.

You may be able to benefit from Colorado’s free anemometer loan program. The most precise information can be obtained by placing an anemometer (a device that measures wind speed) on your site for at least one year. Personal impressions of the windiness of a site are often not reliable – it is better to use an objective measure. No matter what kind of electricity you are using, the best way to reduce expenditures is to use less.Ī small wind energy system may provide you with an economical source of electricity if you live in an area with fairly steady strong winds and at least one-half acre of open land.The cost of residential wind turbines varies depending on how much power they can produce and other factors.A state law passed in 2008 requires all utilities to allow residential turbines of up to 10 kilowatts and commercial turbines up to 25kw to connect to the grid.Winds on your site should be at least class 2 (annual wind speeds averaging 9.8 to 11.5 mph at 50 meters above ground level) to be suitable for wind generation.
