The present invention discloses an air fan turbine positioned horizontally or vertically in close proximity to the exhaust fan system of air handler systems. These turbine units catch the exhausted air flow from the exhaust ports of these air handler units to drive the turbine blades which are attached to a generator. As the propellor blades spin, they generate electricity. Thus, the man made air flow known as exhaust from the air handler systems is used to produce electricity. This invention not only uses man made air flow, but also repositions the air turbine 90° from a horizontal position to a vertical position to receive wind air from the atmosphere. When the air handler unit is turned off, a signal is sent to mechanically move the air turbine to the vertical position to redirect itself to then catch natural wind airflow on both roof top and ground mounted units.
