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 ).
