The electrical power generation system using renewable energy is particularly adapted to provide electrical power to an independent or remotely situated electrical device such as a street light, emergency call box, or illuminated road sign. The system includes a pivotally mounted venturi with vanes assuring that the venturi is oriented into the prevailing wind. A vertical axis wind turbine is installed in the venturi throat, and drives a shaft extending through the column upon which the venturi is installed to a generator at the base of the column. The venturi and vanes may include photovoltaic cells thereon for further electrical power. The venturi may be heated from a geothermal source, and may include a variable diameter internal wall to adjust the cross-sectional area of the throat of the venturi. The use of functionally graded materials and other phase change materials may also improve the performance of the device.
