What are the limitations in obtaining energy from wind?

The limitations in obtaining energy from the wind are as follows:

1. Wind energy farms can be established only at the places where wind blows for a greater part of year.

2. The wind speed to generate wind energy should be greater than 15 Km/h to maintain the speed of turbine as required.

3. There should be some backup facility which should be used to store energy when there is no wind.

4. Establishment of large wind farms are required to large areas of land.

5. It is highly economical.
