The invention relates to a device utilising wind energy. The object of the invention is to accelerate the rate of air flow into the rotor and to increase the pressure differential between the inlet and outlet side of the rotor and in this way to produce a device, by means of which wind energy can be converted more efficiently than hitherto into electrical or mechanical energy, and use of which makes it possible to use both smaller and lighter power generator units and support and/or load-bearing structures of reduced size and strength. This object has been achieved by the device, which comprises wind energy transformer of active/passive type, in which the active part comprises an encapsulated rotor 10 rotating with the air flow and the passive part is an immovable vane system interacting with the rotor, the vane system being anchored in the casing 11, which surrounds the rotor, and its vanes 21, 22 being hollow and provided with air outlet openings, which extend into the hollow internal spaces of the vanes and through which the enclosed outlet space of the rotor 10 has an air flow connection to the atmosphere via the hollow internal spaces of the vanes 21, 22 and the air outlet openings situated in the vane surfaces 26, 27. <IMAGE>
