The growing global energy demand is challenging electrical engineering practices, particularly in recovering waste heat for efficient energy conversion. This study aims to analyze the thermal, energy, and exergy performance of thermoelectric generators (TEGs) designed for waste heat recovery applications. Employing a comprehensive methodology, we assess the heat transfer efficiency of various cooling methods within the TEG system, focusing on passive cooling through natural air convection. Our findings indicate that while passive cooling offers a power-efficient approach without additional energy consumption, it results in higher thermal resistance that impedes overall system performance. The analysis reveals that enhancing the heat transfer capacity at low temperatures is vital for optimizing the energy output of TEGs, particularly in industrial sectors like petrochemicals, where waste heat commonly ranges from 120–160 °C. Insights from this study are crucial for further development of cost-effective thermal designs in TEG-based systems, particularly as global efforts toward sustainable energy solutions intensify. This holistic assessment can inform future improvements in TEG applications for effective waste energy recovery.
