"…[D]emand for…clean power is growing… Focus on Energy co-funded small wind turbine installations are expected to more than double in 2009 compared with 2008…[As small wind] technology improves, a growing number of Wisconsin residents and businesses are investing their time and resources…

"A small wind turbine has a rated capacity of 100 kilowatts, or kW, or less…The electricity output of a wind turbine depends on its size and the wind's speed through the rotor. As wind speed increases, the energy produced increases exponentially…[A] 10 percent increase in average annual wind speed from 10 mph to 11 mph can result in a 33 percent increase in total electricity production…"

"There are many benefits to using wind energy as a source of electricity…[1] The cost of electricity generated from wind power is stable over time and isn't subject to swings in fuel prices…[2] Wind energy is clean, non-polluting and non-depletable. It does not produce smog, acid rain or greenhouse gases…[3] A small wind turbine can help make a home or business energy independent…[4] Wind turbines support the electric utility infrastructure by providing power exactly where it is needed…[5] Building a wind turbine is a way to show your commitment to the community and the environment…

"There are a number of considerations to take into account…Not all locations are suitable…The quantity and quality of the wind resource at a site should be carefully evaluated…A rule of thumb is that small wind turbines should be installed to operate 30 feet above the trees and buildings located within 500 feet of the turbine…[M]ost towers for Wisconsin are typically in the 80- to 120-foot range, or taller…"

"Prior to installing any renewable energy system it's important to ensure your home or business is as energy efficient as possible. For every dollar you spend on energy efficiency, you can save $3 on the cost of your renewable energy system.

"Like any mechanical system, small wind turbines require annual inspections and maintenance…Most installers will offer a service contract option…The first step to implementing a small wind turbine is to learn about wind turbines…Getting a site assessment is the next step…[T]he assessor will provide a written report with feedback and suggestions on using wind power as well as next steps…[Several types of local, state and federa financial assistance are available]…"
