A wind turbine system and a method for controlling a rotational speed of a rotor of such wind turbine system are provided. The system included a wind turbine having a rotor having airfoils having an orientation relative to wind and a rotational axis. The system further includes a structure supporting the wind turbine above ground. The support structure is coupled to the ground. The structure has first portion closer to the wind turbine and a second portion farther from the wind turbine. The first portion will move farther in response to the wind acting across the structure than said second portion causing the turbine rotational axis to tilt. The method includes tilting the rotor rotational axis about an angle, and varying the angle in response to changes of the wind force.
