Question

The power generated in a windmill ___.

• A. has no moving parts
• B. is high near the cities
• 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 spinning of the blades gives power to a generator that produces electricity. So more the velocity of the wind more will the blades spin and more will be the power generated.
The motion of the wind turning the turbine is called the kinetic energy of the wind. This energy is converted into electricity.
