  • The trouble with horizontal axis wind turbines HAWTs

    The Trouble With Horizontal Axis Wind Turbines Hawts

    Feb 22, 2018 Modern wind turbines generate electricity when the wind causes a rotor to spin. The overwhelming majority are HAWTs with three blades. HAWTs consist of three major parts, the tower, the rotor, and the nacelle. Horizontal axis means that the rotor spins around an axis that is parallel to the ground and therefore perpendicular to its tower.
