what do windmills do

Windmills and wind turbines are two different structures that capture wind energy and convert it into useful forms of energy. Windmills are structures that convert wind power into rotational energy using vanes called sails or blades, traditionally to mill grain. They have been used to power many other industrial processes, including paper mills, threshing mills, and to process oil seeds, wool, etc. . Wind turbines, on the other hand, use wind to make electricity. They turn the propeller-like blades of a turbine around a rotor, which spins a generator, creating electricity. Wind turbines rely on a few crucial components to turn wind into the power from electrical outlets. These components include blades, a rotor, a generator, a wind sensor, and a tower. The blades of a wind turbine catch the wind, producing the movement that transforms it into electricity. The size, shape, and number of blades play a significant role in the power of a wind turbine. Wind turbines can be stand-alone or clustered to form part of a wind farm. Wind farms are groups of wind turbines that can turn the power of wind into the electricity used to power homes and businesses.
