This book discusses the topology of exergy as a measure of energy quality with regards to any type of machinery. Because exergy takes the second law of thermodynamics, it is partially destroyed in every process of energy conversion. Consequently, this book focuses on entropy creation in irreversible processes of low temperatures resulting in generation of waste heat. It also addresses ideas on thermodynamic systems and environment, considering temperature, chemical decomposition, and electric potential characteristics and imaging. Finally, the book provides a description of energy utilization expressed as energy efficiency.
