A vertical-axis wind turbine (VAWT) is a wind turbine where the main rotor shaft is arranged vertically, and the main components are located at the base. Key advantages include the ability to accept wind from any direction, which eliminates the need for a yaw system, and a design that places the generator and gearbox at ground level for easier maintenance. VAWTs are often smaller, quieter, and can be better suited for urban or residential areas compared to traditional horizontal-axis turbines.
