Question

How does wind move the large blades of a windmill? Does the windmill work on the principle of mechanical energy?

Answer 1

Wind moves the large blades of a windmill due to the kinetic energy present in the moving air. When the blowing wind strikes the uniquely curved aerodynamic blades, it exerts a force on them, causing them to lift and rotate around a central rotor hub.

Yes, the windmill works on the principle of mechanical energy. It directly converts the kinetic energy of the blowing wind (a form of mechanical energy) into rotational kinetic energy of the blades, which is then used by a generator to produce electrical energy.
