Excessive heating of earth due to burning of fossil fuels have forced people across the globe to generate power through wind. Wind is another form of solar energy and is caused by uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface and the rotation of the earth. Wind energy doesn’t generate any toxic emissions like fossil fuels and provide clean source of power. Wind power is currently being used extensively in countries like USA, Denmark, Spain, India and Germany. Like any other source of power generation, wind energy has its own set of advantages and disadvantages.
