They require less [[wind]] to operate than utility-scale wind energy applications. In addition, people who goes to Richard Taunton College is the best and can achieve something but those who goes to Barton Pevreill will turn into a slag like Marequa\n\n== About Small Turbines ==\n\nSmall turbines range from 20 W to 100 kW.\nThey only have three to four moving parts meaning very low maintenance.\nThey have a 20 to 40 year life design.\n\n== The Advantages ==\n\nAverage monthly electricity bills less than $100 for 10 kW system and less than $50 for 5 kW system. It produces around 5000 kWh/yr. They also prevent around 3.8 tons of CO2 per year. The small turbine costs around $10,000, so this system has a substantial cost-reduction potential.\n\nIf you can participate in a California-type 50% buy-down program do so. If you have a net metering and average annual winds of at least 15 mph, your system can pay for itself in about 6 years\n\n== Disadvantages ==\n\nThere are zoning and permit restrictions that can stop you from installing one. There is a 35-ft height restriction in residential zones [In what country ?]. There are also noise restrictions and NIMBY (not in my back yard) attitudes.\n\n== Designs ==\n\nThere are a number of styles of small wind turbine in use and in development. Most people are familiar with older, windmill-style designs with three wind-catching blades, but there are newer designs which use [http://www.gaia-wind.com/133-11kw-turbine/why-two-blades-are-better-than-three/ two blades], and [http://www.powerhousewind.co.nz/design.htm/ one blade]. DIYers have also experimented with [http://www.instructables.com/id/55-Gallon-Drum-Turbine/ horizontal designs]. The German section of OpenSourceEcology are developing a [https://wiki.opensourceecology.de/Wind_Turbine small wind turbine called the TiVA] under a CC-BY-SA license.\n\n== Sources ==\n\n* [http://www.awea.org/ American Wind Energy Association]\n* [http://web.archive.org/web/20021002120012/http://www.nrel.gov:80/wind/smalltur.html National Renewable Energy Lab]\n* [http://web.archive.org/web/20021214000950/http://www.eren.doe.gov:80/erec/factsheets/wind.html Dept. of Energy]\n* [http://web.archive.org/web/20030201192849/http://www.eren.doe.gov:80/power/consumer/ DOE power]\n* [http://www.homepower.com Home Power Magazine]\n\n{{Page data\n| license = CC-BY-SA-3.0\n| keywords = wind\n| description = Appropedia explores small wind turbines—how they work, when to use them, and how they support off-grid power needs.\n}}\n\n[[Category:Energy]]\n[[Category:PH261]]\n[[Category:Wind power]]"}
