A wind driven turbine installation has a rotatable enclosure with closable inlet and outlet openings. The rotatable enclosure includes a driving arrangement and a wind direction sensor arrangement that monitor the incident wind direction and align the enclosure such that the inlet opening is aligned with the prevailing wind direction. The inlet opening includes an acceleration passage which increases wind velocity and directs the wind to a wind driven turbine device disposed within the installation. The turbine device includes a converging inlet passage, a secondary inlet passage, and an exhaust passage. A turbine rotor is disposed within the turbine device such that wind entering the primary inlet drives the rotor in part by following rotor vanes, and in part by passing across the rotor vanes. Wind entering the secondary passage is redirected toward the primary inlet and drives the rotor in the forward direction. Wind from the secondary passage is confluent with wind from the primary inlet that passes through the rotor. The confluent air flow exhausts through the rotor at the exhaust opening where that portion of the primary air which follows the rotor is also exhausted. The wind turbine device may be mounted for rotation about a vertical axis within the secondary housing so as to adjust itself to the direction of the prevailing wind.
