Hybrid Power Systems (HPS) integrate renewable and traditional energy sources to provide sustainable and efficient power solutions. This review explores HPS implementations in Canada, the United States, and Africa, highlighting their economic, environmental, and technological aspects. HPS combine diesel generators, solar, and wind energy, supported by battery storage and smart grid technologies, to ensure reliable power supply. Economic analyses show that while initial costs are high, long-term benefits include reduced operational expenses and energy independence. Environmentally, HPS significantly reduce greenhouse gas emissions and resource depletion. Technological challenges, such as intermittency and system optimization, are addressed through advanced storage, smart grids, and microgrid technologies. The study emphasizes the need for research, education, policy support, international collaboration, public awareness, and ongoing technological innovation to promote HPS adoption. The mining industries in Canada, the United States, and Africa vary in resource availability, regulatory frameworks, and economic dynamics, influencing HPS implementation. The paper concludes that HPS are essential for sustainable energy solutions, offering a path toward a resilient, efficient, and environmentally conscious global energy landscape.Hybrid Power Systems (HPS) integrate renewable and traditional energy sources to provide sustainable and efficient power solutions.
