The majority of wind turbines have a horizontal axis: a propeller-style design with blades that rotate around a horizontal axis..
The wind causes the rotor blades to spin around their axis. This rotary motion is transmitted to the generator via a connected shaft..
A turbine blade is similar to a rotating wing. Differences in pressure cause the blades to both bends and rotate..
Since the wind flows more quickly along the curved edge, it creates a pressure difference, causing the blades to rotate. Learn more in our guide to the key parts of wind turbines. [pdf]

When blades rotate slowly, they interact more effectively with the wind. This slow rotation allows the blades to align better with the wind direction, maximizing the capture of wind energy..
When blades rotate slowly, they interact more effectively with the wind. This slow rotation allows the blades to align better with the wind direction, maximizing the capture of wind energy..
If there is too little wind and the blades are moving too slowly, the wind turbine no longer produces electricity. The turbine starts to create power at what is known as the cut-in speed..
If the turbines propeller blades rotate too slowly, it allows too much wind to pass through undisturbed, and thus does not extract as much energy as it potentially could..
Feathering the blades slows the turbine's rotor to prevent damage to the machine when wind speeds are too high for safe operation. [pdf]
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.
