According to the invention, to use wind energy, a flow is conducted effectively onto a rotor to convert the flow energy by means of a steering mechanism. According to the invention, the steering mechanism permits: the wind to be conducted from a point of higher wind speed to a point of lower wind speed that is preferred for the installation of the rotor; the flow cross-section to be narrowed and compressed, thus increasing the flow speed; one side of a rotor with an axis running transversally to the wind direction to be shielded; and/or a suction effect to be generated downstream of the rotor in the flow direction. The device comprises a hollow tower (2) with a wind trap opening (5) at the upper end and a flow channel that is formed by the hollow cross-section of the tower (2), said channel leading downwards to at least one rotor (12; 14) that is located in the vicinity of the ground for converting the flow energy. An outlet (13) for the air is situated downstream of the rotor. An upper end section (3) of the tower comprising the wind trap opening (5) can be rotated (4).
