Why can wind energy farms be established only at specific locations? Give reasons to support your answer.

(N/A) Wind energy farms can be set up only at specific locations due to the following reasons:
$(i)$ They require locations where wind blows for the greater part of the year.
$(ii)$ The wind must be strong and steady,typically having a speed of at least $15\, km\, h^{-1}$ to rotate the turbine effectively.
$(iii)$ $A$ large,open,and free space is required to install multiple wind turbines without obstruction.
Since these specific environmental and geographical conditions cannot be satisfied everywhere,wind energy farms can only be established at selected locations.
