The power generated in a windmill [NCERT Exemplar](a) is more in rainy season, since damp air would mean more air mass hitting blades(b) depends on the height of the tower(c) depends on wind velocity(d) can be increased by planting tall trees close to the tower

(c) Wind energy farms can be located only in vast open areas located in favourable wind conditions as the minimum velocity for a windmill to functions is 11-16 km/h and is called as cut in speed. Thus, the power generated in a windmill depends on wind velocity.
