A propeller is an essential component in a windmill, as it plays a vital role in harnessing the power of the wind to generate energy. The propeller's blades are designed to catch the wind and convert its kinetic energy into rotational motion. This rotation then drives a mechanical system, such as a generator or pump, to perform work. Thus, without a propeller, a windmill would be unable to function effectively in capturing and utilizing wind power.
