Small Wind Turbine[edit | edit source]
Small wind turbine is a small turbine that is used for house holds and farms. 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
About Small Turbines[edit | edit source]
Small turbines range from 20 W to 100 kW. They only have three to four moving parts meaning very low maintenance. They have a 20 to 40 year life design.
The Advantages[edit | edit source]
Average 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.
If 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
Disadvantages[edit | edit source]
There 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.
Designs[edit | edit source]
There 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 two blades, and one blade. DIYers have also experimented with horizontal designs. The German section of OpenSourceEcology are developing a small wind turbine called the TiVA under a CC-BY-SA license.
