Abstract: The dire need of the present era is generation of power at high voltage levels in a cost-effective and an eco-friendly manner. Against this backdrop, this paper discusses the concept of piezoelectric potential difference generation using a combination of solar energy and wind energy simultaneously in an integrated manner. Due to solar energy, the thermal stress created in one member develops mechanical stress in another member and the mechanical stress, thus developed, is responsible for the generation of potential difference. In the case of wind energy, elastic deformation in the spring attached to the rotor mill develops mechanical stress in the quartz bar which leads to piezoelectric potential difference generation. Further, the device has an advantage over conventional solar cells or windmills owing to reduced wear and tear, no hazard from dust, operational flexibility in both odd and even weather conditions, among others.
