ABSTRACT

A windmill is a machine that converts wind's energy into rotational energy, typically using sails or blades. Historically, windmills were used for mechanical tasks like grinding grain or pumping water, while modern windmills, more accurately called wind turbines, generate electricity. The process works by wind pushing against the blades, causing a shaft to spin, which connects to a generator that produces electricity. A wind turbine is a device that converts wind's kinetic energy into electrical energy. It works by using large blades, which are designed like airplane wings, to capture the wind's force, causing them to spin. This rotation turns a shaft connected to a generator, which then produces electricity. Wind mill: Wind energy to mechanical energy: Wind flows across the angled blades, creating a difference in air pressure on each side. This difference generates lift, which is stronger than drag, causing the rotor to spin. Wind turbine: Mechanical energy to electrical energy: The spinning rotor connects to a generator, either directly or through a gearbox, which converts the rotational energy into electrical energy.
