The present invention is a wind driven power generator that has a rotational shroud assembly that has a base portion that is attached to a plurality of rotational base guides. A structure base has an annular shaped receiving rotational track that the rotational base guides rotate within. There is a turbine assembly that rotates within the shroud assembly which has a top portion and a shaft end. The shaft end extends through the base of the rotational shroud assembly and through the structure base. The top portion of the turbine assembly has at least one elongate arm that has a first arm end and a second arm end. The arm is attached to the shaft near the top portion of the turbine assembly and equidistance from the first arm end and the second arm end. Each arm is essentially perpendicular to the shaft of the turbine assembly. There is at least one vertical wind blade attached to each of the first arm ends and the second arm ends. Each of the wind blades has a wind side that incoming wind contacts and a back side opposite the wind side. The wind blades are spaced equidistance apart around the shaft of the turbine assembly. The rotational shroud assembly covers approximately half of the turbine assembly throughout the rotation and shields the back side of the blades from the incoming wind during rotation. The turbine assembly rotates independently from the rotational shroud assembly and the shaft end is coupled to a rotational energy conversion device.
