The continuous growth in population, urbanization, and technological advancement has resulted in a rapid increase in electrical energy demand. Conventional energy sources are not only limited but also responsible for environmental pollution. At the same time, a significant amount of human mechanical energy generated during physical activities such as gym workouts is wasted without any productive use. This research paper presents the concept of Harnessing Electricity from a Hybrid Green Gym, where human effort and solar energy are combined to generate electrical power. Mechanical energy produced during pedalling is converted into electrical energy using a generator, while solar energy acts as an additional and reliable source. The generated energy is stored in a battery system and can be used to operate small electrical loads. The proposed hybrid system ensures power availability during grid failures, power cuts, and environmental calamities. The system is eco-friendly, cost-effective, and suitable for decentralized energy generation. It also promotes physical fitness along with energy conservation.
