How does a wind turbine work?
Wind turbines convert the kinetic energy of wind into electricity. Modern wind turbines operate by wind turning propeller-like blades, which then drive a generator via shafts and gears. The two main types are horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). HAWTs, the most common, resemble airplane propellers and have two or three blades. VAWTs can harness wind from any direction and have blades that rotate around a vertical pole. The rotation of the blades drives an electrical generator, converting mechanical energy into electricity. These turbines can be used individually or in wind farms for larger-scale electricity production.
