Abstract: A solar and wind energy collection system includes a solar energy collecting structure and a wind turbine disposed on a common supporting surface. The solar energy collecting structure includes a frame that defines the lateral surfaces of a frustum and one or more photovoltaic cells that collect energy from sun light to generate electricity. The wind turbine includes a tower affixed to the supporting surface and extending therefrom within the lateral surfaces defined by said frame while elevating past said frame through an opening on the apex of the frame. The wind turbine also includes a nacelle mounted on said tower and a rotor coupled to the nacelle. The rotor includes a rotatable hub and at least one blade. In one embodiment, the blade has one or more air conduits that provide a fluid connection between opposite high-pressure and low-pressure faces of the blade.
