Vertical-axis wind turbines: what makes them better?
For instance: Efficiency – When the wind blows on the blades of a HAWT, all of them contribute to energy production. When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely 'go along for the ride'. The result is comparably reduced efficiency in power generation.
