The invention relates to the field of wind energy. The wind energy installation comprises at least one energy module (1) with a vertical axis of rotation, which energy module is designed to enable the vertical installation of at least one additional module. The energy module (1) comprises rotor blades (6) which are fixed to a bearing cylinder (5) and are flat, said rotor being arranged inside a stator, which is formed by a system of vertically positioned wind guide plates (7). The wind guide plates (7) are designed to be capable of changing in area on account of a telescopic movement of a movable sector (8) thereof, which movable sector can be arranged both inside and outside said wind guide plates. The rotor blades (6) are equipped with vortex generators (9), which are in the form of curved strips. The arrangement of the rotor blades (6) relative to the bearing cylinder (5) is designed so as to form a slotted diffuser (10) between said rotor blades and the bearing cylinder (5). In the event that the wind energy installation is intended to be used for generating electrical energy, a permanent magnet generator (12) with distributed stator windings is mounted on each of the ends of the rotor. The wind energy installation has increased effectiveness in use in comparison with similar known installations, inter alia as a result of an increase in the efficiency and the possibility of operation at low wind speeds
