This study addresses the growing need for enhanced thermodynamic efficiency in renewable energy systems, crucial for sustainable development. The objective of the research is to analyze and compare the performance of various renewable energy technologies across different climatic conditions. The methodology involved a comprehensive review of current thermodynamic principles applied in solar, wind, and hydroelectric systems, followed by experimental simulations implemented at each institution. Key findings reveal that regional climatic variables significantly influence efficiency, with solar thermal systems in arid environments exhibiting up to 20% higher performance. Wind energy systems demonstrated optimal thermodynamic efficiency in subtropical coastal areas, while hydroelectric systems showed consistent performance across varied climates. The study concludes that tailored optimization strategies for each renewable energy type can enhance thermodynamic performance and suggests further research into hybrid systems. This research contributes to the design of more efficient renewable energy solutions, reinforcing the critical role of thermodynamics in addressing global energy challenges.
