Nevertheless, wind power does appear to represent a viable alternative energy sources in some regions of the country and elsewhere in the world today. Indeed, by 2002, India had already installed 1,167 megawatts of wind farms; further, Canada, Japan, Norway, and Germany have active Joint Implementation Programs that provide support for their wind power programs, and Costa Rica has three wind power projects included among its alternative energy initiatives (Ottinger 2002:331)
Across the country signs are growing that 'small wind' (a category that includes wind generators geared to supply a single home) is catching on in suburban and even urban settings" (2). Such smaller applications may become more attractive for residential, small business, and farm use in the future as well (Clayton)
12). Wind power is called a renewable energy source because it depends on natural energy flows and sources in the environment, which, since they are continuously replenished, never become exhausted (Elliott 129)
This rapid growth is attributed to a number of factors, including both increasing environmental awareness and decreasing economic costs" (341). In addition, heightened awareness and growing worries over the impact of fossil-fuel energy sources on global warming in recent years has further accelerated interest in alternative energy sources, especially wind power (Hansen)
com/2007/08/wind-farm.jpg In recent years, wind farms have also sprung up all over Europe and currently contribute a significant percentage of many Western European nations' power requirements today (Holzman 358)
These authors report that, "Wind has been used as a source of power at least since it filled the sails of seafaring travelers 5,000 years ago. Windmills have been used since the early 1900s for agriculture and to pump water" (Pernin et al
India produced 1,167 megawatts in 1999 from their "wind farms." Denmark, the country that pioneered the use of modern windmills to generate electricity, used the source to produce 14% of their energy needs in 1999 (Pasqualetti, 2000)
There is absolutely no such thing as an entirely clean source of energy. (Boyle & University, 2004) There are primarily two sources of energy: Non- Renewable Energy Sources- These sources of energy cannot be replenished

The consequences from this disturbance could cause problems of viability of individuals and increased potential for impacts due to cumulative effects from other impacts such as chemical pollution combined with stress induced by noise. (Evans, 2007) Many who are against the development of wind power argue that wind turbines cause visual disturbances
It is considered to be a fact that the development of renewable energy sources and especially wind energy is the only -- medium term solution to the problem of climate change. (Kruger, 2006) (Boyle, 1996) It is because of this that many countries have moved towards generating power by using this source
Vortex Shedding (Fish Schooling) A brand new origin of ideas for wind farm designers originates from an improbable place: the ocean. By emulating schools of fish, designers can improve wind farm production-potentially obtaining as much as ten times additional energy via the exact same site in comparison to conventional wind farms (Schwartz, 2011)
Their calculations reveal that the energy-per-acre of the wind farm might be elevated a hundredfold. Following that, they will construct an evaluation area with genuine turbines and produce actual power production data (Whittlesey and Dabiri, 2010
Current efforts within the improvement of the inboard area have analyzed flatback or perhaps blunt trailing-edge airfoils. Whilst a noticeable difference around conventional solid airfoils, flatback airfoils nonetheless experience from higher drag and also noise via vortex expulsion; this vortex expulsion additionally cuts down on quality involving the wind for downstream generators (Wirz and Johnson, 2011)
If there were less expensive means of storing wind energy, the situation could be better, thus the only hope is that there will be developments in storage technologies in the next few years so as to improve reliability (Doherty, Outhred & O'Malley, 2006). Furthermore, good wind sites are frequently only available in locations far away from cities where the power is needed, and long transmission lines have to be built to take the power where it is needed (Bergmann et al
The cost competitiveness of power is, however, dependent on the location of the wind farm. Even though the cost of setting up wind power stations has significantly reduced in the past few decades, the mode of power generation still requires significant initial investments, if it is to compete favorably against hydrocarbon sources (Denny & O'Malley, 2007; Dale, Milborrow, Slark & Strbac, 2004)
However, needless to say, other wind turbines might require more money to maintain than others. But, still generation of electricity using wind power is still one of the cheapest-priced forms of renewable energy today, and often costs between 4 to 6 cents per KWh (Kilowatt-hour), based on the initial investment and the location of the wind farm (Doherty, Outhred & O'Malley, 2005)

To produce electricity on an enormous scale, there is a need for a large number of windmills to be set up over an area with high wind speeds (a minimum of 15-kilometer per hour). A place whereby windmills have been set up to harness wind energy is referred to as a wind energy farm (Provey, 2009)
But how does it work? Wind is created by the sun's rays, which heat the earth differentially. As the earth heats and cools, it releases energy in the form of wind, which has been estimated to contain "10 million MW of energy" at any one given time (Herbert et al
