Question

The power generated in a windmill:

• A. Is more in rainy season since damp air would mean more air mass hitting the 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

Answer 1

The correct option is C

Depends on wind velocity

The wind makes the rotor spin; as the rotor spins, the movement of the spinning blades gives power to a generator which produces electricity. As the velocity of the wind increases, the rotation of the turbine increases, thus increasing the amount of power generated.
