Number of windmills erected over a large area is known as wind energy farm.

The practical application of a windmill farm is energy output of each windmill in the farm is coupled together to get electricity at a commercial scale.

Limitations of using a wind energy farm

•wind energy farms can be established only in those areas where wind blows for a greater part of the year

•Wind speed should be higher than 15km/hr to maintain the speed of turbine

•There should be some backup facilities like storage cells, to take care of energy needs during a period when there is no wind
