What are the limitations on obtaining enegry from wind ?

Explanation

The limitations in obtaining energy from wind are as follows
(i) It can be established only at those places where wind blows whole of the year.
(ii) The minimum wind speed necessary for satisfactory working of a wind generator is 15 km/h, which is not gained continuosly.
(iii) Wind energy farm requires quite large area of land nearly 2 hectares land is needed for 1 MW generator.
(iv) The setting up of wind energy farm is very expensive.
(v) As the blades are exposed to vagaries of nature like rain, the sun, storm and cyclone, they need high level of maintenance.
(vi) The wind energy farms disturb rainfall pattern.
