But wind production is costly and India needs to find ways to produce wind energy at economical rates. For this reason, skilled technicians and designers are looking into the possibility of cost reduction "by increasing the size, tailoring of turbines for specific sites, exploring new structural dynamic concepts, developing custom generators, and power electronics, in addition to implementing modern control-system strategies." (Orosa, 2010)
It has been found that in order to reduce cost and produce energy more efficiently; some of the important factors to keep in mind would be "the power in the wind, the load factor, wind turbine -- axis orientation, the area required, and the grid connection." (Orosa, 2010)
Solutions are needed in troubled areas. For example when wind power is high, electricity generation is not an issue but when it's low, there may be extended periods of no production at all. A solution is needed for this which has been proposed in the form of change in rotors. One researcher proposed the use of a wind concentrator (Shikha, 2003) while further research looked into the possibility of "phase change of moist air. This recent implementation is based on the Foehn effect and consists of a nozzle, a rotor, and a diffuser designed to get the maximum mechanical energy from the free stream of airflow." (Orosa, 2010) the research finally came up with solution in the form of Savonius rotor which improves wind pressure in areas marked by long periods of low winds.
The most critical factor is the correct use of axis-orientation of turbines. For this reason, technicians and designers have looked into the use of both HAWTs and VAWTs. It has been found that VAWT has more benefits to offer than the traditional HWAT turbine...

Current and Future Trends in Wind Power Applications. While the foregoing wind power initiatives would indicate that wind farms are already contributing a large percentage of the nation's energy needs, the research shows that this is far from the case. In this regard, the current total respective renewable energy consumption rates based on source in the United States
Wind Power The greatest challenge of the 21st century is filling the gap between energy demand and supply with clean, reliable and green source of energy. Energy is very essential and it is in material form in everything that is around us. The opportunity cost of obtaining the energy that we require is the impact that is made on our environment. Some energy sources have greater impacts while others have relatively
Wind Power In 1987, Renner and Renner wrote, "One year after the dramatic collapse of world oil prices, any initial enthusiasm about it has yielded to a more sober assessment of the inter- national energy market. The predicted benefits of the oil price drop have turned out to be grossly overstated: cheap, abundant oil is clearly not the solution to the world economy's deep structural problems. Moreover, oil does not seem
In fact, during 2007 alone, the installed capacity of "on grid" small-wind residential generators almost tripled, from 1,300 kilowatts nationwide in 2006 to 3,000 kilowatts in 2007 (Clayton). According to Clayton, the number of residential installations increased from 400 to 1,200 units during 2007 as well. In response to this growing demand, a number of companies have started producing various wind turbine configurations in smaller versions for this market
The little occasion utmost torque of a rotor twice-fed electric machine is of higher frequencies and capabilities unlike other machines used within the frames of generating power in the society. Several avenues of operation are used within this notion of realizing the existence and consequence of having a firm body of generating any amount of energy to be used in the field. In order to foster equitable management of
The production of electricity from power plants relying on this varying resource changes considerably. On the other hand the electricity demand does not cope with such variations. (Komor, 2009) • Other forms of barriers: There are some other obstacles like allowing challenges of renewable power plants and technical hazards with regard to transmission connecting to the plant, higher proportion of capital to operating costs and policy instability. (Komor, 2009) The prime
