Wind mills on a wind farm
Wind energy is good for our economy, environment and energy security because of the potential for owner revenue, revitalization of the rural communities and reduction of dependence on the power grid -- all without consuming natural resources or emitting pollution or greenhouse gases.

In a typical wind turbine, wind energy is converted to rotational motion by a rotor, which turns a shaft that passes into a gearbox, which increases the rotational speed. This transmission is attached to a high-speed output shaft, which is connected to an electrical generator.

Wind turbines come in a variety of sizes depending on the planned use for the electricity. Some wind turbines are used to charge batteries for buildings not connected to the utility grid. Some turbines can supply all or part of the electricity used by a business or farm. Large-scale wind farms with multiple turbines are used to harvest the wind above acres of land, usually to feed power into the electrical grid. Whatever your application, Johnson Controls can provide a complete wind power solution.

Is this the right technology for my situation?

The following elements are important for wind to be a viable option.
For each MW of electricity to be produced, a free-standing turbine typically needs up to 6 acres of land
To determine wind generation capabilities, a study of wind speed and quality must be done
If overproducing electricity for your own use, access to an electrical grid is important
Wind incentives and tax credits in your state may help fund wind products

Wind Power Facts:

(Source: American Wind Energy Association – 2007 Wind Energy Fast Facts)
Electricity generated from the wind in the U.S is estimated at 31 billion kWh in 2007
U.S. wind energy potential is estimated at 10,777 billion kWh annually, more than twice the electricity generated in the U.S. today
Industry growth rate in the U.S. averaged 22% from 2001 - 2006
A single, utility-scale wind turbine provides $3,000/year or more in income to a landowner leasing his wind rights
Wind has one of the highest energy payback ratios of any power technology
