Wind Energy Advantages And Disadvantages

Energy cannot be created nor be destroyed , only possible form is that it can be converted from one form to another. Energy consumption is normally discussed but actually it is getting transformed rather than getting consumed. Life is a continuous process of energy conversion and transformation. Civilization is effectively achieved through the increasingly efficient and extensive harnessing of various forms of energy. For continuous human development energy is indispensible, providing adequate energy is essential for eradicating poverty, raising living standards and improving human welfare worldwide. But energy production and conversion always led to generation of undesirable products and emissions at least in the form of dissipated heat, There comes the importance of renewable energy sources. Wind power is a strong candidate towards a sustainable future. Wind energy is non polluting and is freely available in many areas. Wind

Approximately 2.5% of incident radiations are used for atmospheric movements. If this is theoretically calculated overall wind power of approximately 4.3*105 W is obtained. This energy in the moving air masses can be converted into much or electrical energy by suitable wind mills or turbines. The following section details the main basic principles of the supply in wind energy and its characteristics. Wind energy converters harness the kinetic energy contained in flowing air masses. Most modern wind energy converters are equipped with rotors to extract wind power and consist of one or several rotor blades. Wind power generates rotation of the rotor and thus mechanical power is produced at the rotor shaft. This power can be transmitted through suitable mechanism to a generator to produce electrical output. Thus the wind power station consists of a wind energy convertor(rotor), a mechanical gear and
