Hybrid Renewable Energy Generation Using Piezoelectric And Solar

The increasing demand for electrical energy and the rapid depletion of conventional energy resources have made renewable energy sources an important alternative for sustainable power generation. This paper presents a hybrid renewable energy generation system that utilizes both solar energy and piezoelectric energy for electricity generation. Solar panels convert sunlight into electrical energy using photovoltaic cells, while piezoelectric sensors generate electrical energy when mechanical pressure such as human footsteps is applied. By combining these two energy sources, the efficiency and reliability of energy generation can be improved. In this system, solar energy is used as the primary source of power during daytime, while piezoelectric sensors generate electricity from mechanical pressure created by human movement in crowded areas. The electrical energy generated from both sources is stored in a rechargeable battery and can be used to power small electrical loads such as LED lighting systems, sensors, or low-power electronic devices. This hybrid renewable energy system can be implemented in public places such as railway stations, bus stands, shopping malls, and footpaths where human movement is frequent. The system helps in utilizing wasted mechanical energy and natural solar energy effectively. The proposed system contributes to energy conservation, reduces dependence on conventional power sources, and promotes the use of clean and sustainable energy technologies.
