WIND

Wind power is the conversion of wind energy into a useful form, such as electricity, using [|wind turbines]. Today, wind energy is mainly used to generate electricity. Wind is called a renewable energy source because the wind will blow as long as the sun shines. The blades collect the wind's kinetic energy, by turning the blades on the milll, the blades are connected to a drive sgaft that turns an electric generator to produce electricity People have started relying on wind power more and more as it is a sustainable resource, and will be useful as long as the sun is shining. Although wind power farms or singular windmills are quite expenisve to install, in the long run it will save you alot of money. Another disadvantage of using wind power is that when it isnt windy, there is a lost oppurtunity to get energy. Because wind power is a sustainable resource, more people should start using it because it.

 * Why use windpower?**

The most serious environmental drawbacks to wind machines may be their negative effect on wild bird populations and the visual impact on the landscape. To some, the glistening blades of windmills on the horizon are an eyesore; to others, they’re a beautiful alternative to conventional power plants. http://www.eia.doe.gov/kids/energyfacts/sources/renewable/wind.html

- relatively safe energy for supply of electricity -help to reduce the stress on an already battered environment as well as help the economy - absolutely renewable, as it takes no fuel or other resources that can be expended. - Wind farms do not produce extreme noise, and they have not shown any affect on farms, other livestock, or tourism concerns. -widely distributed -cheap -reducing toxic gas emissions -everyone can use it ! no boundry or territory limits - local communities or organizations can build the wind turbines, and supply energy to themselves and not have to rely on power sources, can even sell extra energy and make a profit || - reqiure spaces -expensive to build -a large number of turbines have to be built to generate a proper amount of wind energy - it is unpredictable, no electricity if there is no wind, cannot depend completely on wind power -non-dispatchable,the amount of wind supplied to a place and the amount of energy produced from it will depend on various factors like wind speeds and the turbine characteristics - wind turbines are heavy and destructive to roads, especially because you usually build a lot in a nearby space -expensive or hard to maintain || source:http://www.streetdirectory.com/travel_guide/113614/science/the_advantage_of_using_wind_energy.html http://www.buzzle.com/articles/advantages-disadvantages-wind-energy.html
