Abstract: Electrical power may be generated from wind and/or solar inputs. A plurality of rotor blades may extend radially from a rotor hub. The rotor blades may rotate about the rotor hub under the influence of an incident wind to produce an electrical current from a generator retained within a nacelle. Photovoltaic films may cover at least a portion of the surfaces of the rotor blades. The rotor blades may be detachable from the rotor hub for use in a solar panel arrangement. The rotor blades may be folded to enclose the nacelle for transporting the system.
