<p>This paper provides a comprehensive review of several multi-generation energy systems performance, especially energy and exergy analysis. An examination of exergy analysis of multi-generation energy systems, which primarily rely on solar, fuel cells, and biomass, is carried out. To mitigate the release of greenhouse gases, particularly carbon dioxide, and to achieve cost savings, various configurations of multi-generation energy systems and their designs are investigated. Furthermore, to explore various alternative methods of energy generation in multi-generation energy systems, it is imperative to look into the techniques which minimize losses, wastes as well as decrease operational expenses. Moreover, several multi-generation energy systems are compared against their energy and exergy characteristics in order to ascertain the best systems. Additionally, this review discusses different optimization approaches employed in multi-generation energy systems. Based on the analysis, it is found that meta-heuristic techniques are mostly employed in the fields of multi-generation energy system research. Furthermore, the research investigates the obstacles that hinder the implementation of multi-generation energy systems. In addition to a review of various types and methods of multi-generation energy systems, this survey provides specific information on advancements made in the proliferation of multi-generation energy systems and their technological growth. Indispensable multi-generation energy system parameters like power output, energy, exergy efficiency, water, hydrogen production, and other relevant factors are quantified while demonstrating its performance. Finally, this review highlights the potential future scope for multi-generation energy systems implementation and operation.</p>
