horizontal-axis wind turbine
Quick Summary
A horizontal-axis wind turbine (HAWT) is a device that converts the kinetic energy of wind into electricity. It features a rotor with blades that spin and drive a generator. While older "windmills" were used for mechanical tasks like milling or pumping water, modern HAWTs are primarily for electricity generation.
HAWTs are the most common type, often resembling aircraft propellers with two or three long blades. They are designed for efficiency in electricity production and are frequently grouped into wind farms. The amount of power generated is influenced by factors like blade design, rotor size, and wind speed, with a theoretical maximum efficiency of about 59% according to Betz's Law.12
