Wind power in Illinois provided nearly 10% of the state's generated electrical power in 2020 powering 1,231,900 homes. [1] At the end of 2020, Illinois had 6,300 megawatts (MW) of wind power installed, ranking fifth among states for installed wind turbine capacity. [ 2 ]
The passive yaw systems utilize the wind force in order to adjust the orientation of the wind turbine rotor into the wind. In their simplest form these system comprise a simple roller bearing connection between the tower and the nacelle and a tail fin mounted on the nacelle and designed in such a way that it turns the wind turbine rotor into ...

Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.
The 300 MW Streator Cayuga Ridge South Wind Farm, located near Odell, Illinois, officially started generating power in March 2010. [1] The developer received a $170 million grant through the U.S. Department of Treasury's Section 1603 grants-in-lieu-of-tax-credits program. [ 2 ]
λ is a characteristic of each specific windmill, and for a Savonius rotor λ is typically around unity. For example, an oil-barrel sized Savonius rotor with h= 1 m and r= 0.5 m under a wind of v= 10 m/s, will generate a maximum power of 120 W and a maximum angular speed of 20 rad/s (190 revolutions per minute).
The Mendota Hills Wind Farm originally consisted of 63 Gamesa G52-800 kW wind turbines, each costing around US$1 million. Each turbine stands 214 feet (65 m) tall and has a diameter of 171 feet (52 m) across the rotor, the two ton rotors spin at 25 rpm. [1] Each of the three blades measure 83 ft (25.91 m) long. [1]
