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 blades spinning gives power to a generator which produces electricity. So more the velocity of the wind, more will the blades spin and more will be power generated.

The motion of the wind turbine turning is called kinetic energy, this power is converted into electricity.
