SMALL SCALE GENERATION BY HARNESSING THE WIND ENERGY

Abstract

Generating electricity from wind has been centered around the rotation rotating windmill in which rotating shaft coupled to the generator used to generate electricity. Other sources such as solar power hydropower, thermal power, wind power are used for generating electricity in kilo watts and megawatt but there is no such kind of application which can generate electricity on sub 100watt scale. So as to generate electricity on small scale and to provide cheap source of energy for lighting the houses in remote where there is no other sources are available. And to generate a power source that can be constructed with the help of local material and if problem occurs that can be fixed by the local people. About 2% of global electricity production comes from wind-powered generators. Their capacity has doubled in the past few years. In some countries it is more popular than solar energy because it is cheaper on a cost per watt basis. However, for powering small devices there has been minimal activity to harvest energy from the wind. This is because conventional electromagnetic wind turbines require rotating fins and gearing which adds bulk, and they become less efficient when scaled down.
