They usually produce between 500 W and 10 kW, with some as small as 50 W. The Canadian Wind Energy Association considers small wind turbines to be up to 300 kW, [1] while the IEC 61400 standard defines them as having a rotor area smaller than 200 m 2 and generating voltage below 1000 Va.c. or 1500 Vd.c.
[citation needed] The Fuller Wind Turbine System was a bladeless wind turbine announced in 2010 by Solatec LLC. Saphon Energy announced a bladeless wind turbine in 2012. [27] Vortex Bladeless is attempting to produce a wind turbine that isn't actually a turbine. All generators require a magnetic field, a conductor and motion to produce electricity.
In addition, there is currently no competitive market for wind energy (though there may be in the future), because wind is a freely available natural resource, most of which is untapped. [116] The main cost of small wind turbines is the purchase and installation process, which averages between $48,000 and $65,000 per installation.
A new wind energy technology is being developed that converts energy from wind energy vibrations to electricity. This energy, called Vibro-Wind technology, can use winds of less strength than normal wind turbines, and can be placed in almost any location. A prototype consisted of a panel mounted with oscillators made out of pieces of foam.
Enron Wind (now defunct) – wind-turbine manufacturing assets bought by General Electric in 2002; Fuji Heavy Industries (Japan) – the wind turbine business was acquired by Hitachi in 2012; Gamesa (Spain) NEG Micon (Spain) – was bought by Gamesa; NEG Micon – now part of Vestas; Nordic Windpower (USA) – bankrupted in 2012; Raum Energy ...
The wind energy sector can also produce jobs during the construction and operating phase. [102] Jobs include the manufacturing of wind turbines and the construction process, which includes transporting, installing, and then maintaining the turbines. An estimated 1.25 million people were employed in wind power in 2020. [103]
