A wind turbine comprising a rotor with plural blades and a controller arranged to independently control each of the blades e.g. pitch and/or one or more components of each blade e.g. slats, tabs, when wind speed or force acting on the blades is above cut-out 166 in order to reduce a mechanical load experienced by at least a part of the wind turbine e.g. blades, tower or foundations. The controller also independently controls each of the blades and/or blade components to increase a driving moment 156, 160 of each blade independently of other of the blades when speed or force of wind acting on the turbine is below rated e.g. 154 below cut-in, Vmin, or when operating at part load 158 to maximize output. At rated speeds a conventional pitch control 164 is used. At the same time as individual pitch control there may be a yaw control to either increase drive or reduce loads as appropriate.
