The ratio between the speed and the wind speed is called . High efficiency 3-blade-turbines have tip speed/wind speed ratios of 6 to 7. Wind turbines spin at varying speeds (a consequence of their generator design). Use of and has contributed to low , which means that newer wind turbines can accelerate quickly if the winds pic.
