The invention relates to a wind energy turbine comprising a rotor with at least one rotor blade (10) and a displacement unit (12) for the rotor blade (10). An increase in the size of the turbine and consequently that of the rotor blades requires an increase in the size of the drives for the rotor blade displacement. This in turn requires a greater investment in logistical, temporal and material resources, especially if damage occurs. To avoid these disadvantages, the turbine is provided with a displacement device comprising more than one drive. Each drive thus produces a fraction of the power, allowing it to have smaller dimensions and impinges upon the components connected downstream to a corresponding lesser extent.
