Utilize Wind Energy
In the earth wind energy is coming under non conventional energy resources and we can find massive utilization of wind for producing electricity. Generally in the coastal region, sea sides, river sides, hill sides we can see large wind mills and the bale of the wind mill get rotated with the force of the wind and in turn following the alternator to make electric. It is really a very cheap way to produce and the cost is very lower but the installation cost is high. Demerit of it the wind flow is not uniform in all seasons so the production varies.
