Ramifications of the second law of thermodynamics on sustainability


The 2 nd law of thermodynamics deals with the non-conserved entities of entropy and exergy as well as quality. The 2 nd -law efficiency defines perfection, and helps us quantify how close we are to perfection. A process with a 2 nd -law efficiency of 100% is thermodynamically perfect. As such, it involves no entropy generation, no exergy destruction and thus no waste of resources. Therefore, the 2 nd law is closely related to the concepts of sustainability, green practices, effectiveness, efficiency, and performance. The concept of 2 nd -law efficiency has important implications on enterprises such as technology development and innovation activities to assess efficiency and effectiveness, and the best utilization of resources. Energy efficiency and the harvesting of renewable energy are also associated with the 2 nd law. In this presentation, energy conservation, renewable energy and sustainability are examined from the 2 nd -law point of view. Then the 2 nd -law concepts are applied to technology development and innovation activities to assess their efficiency and effectiveness and thus the best utilization of resources.


Yunus Cengel has been working as a faculty member at the University of Nevada, USA since 1984. Professor Çengel was the Dean of the Faculty of Mechanical Engineering at Yıldız Technical University between 2010 and 2012, and the founding dean of the Faculty of Engineering at Adnan Menderes University between 2012 and 2016. In 2012, he also served as the Advisor to the President in charge of international cooperation at TUBITAK. He also served as a consultant to many public and private institutions. Professor Çengel completed his undergraduate education at Istanbul Technical University and his doctorate from North Carolina State University in the USA. He is the author of numerous textbooks published by McGraw-Hill, widely used around the world and translated into many languages. He has also given conferences, prepared reports and written articles on various topics. Yunus Çengel, who is an engineer and based on questioning and critical thinking in his professional life, has a special interest in researching reality in the light of relevance to reason and science, compatibility with observations and rationality.
