Abstract
Engineers constantly search for ways to increase the efficiency of systems. An increased efficiency translates into an increased output for the same consumption of the fuel or energy source or a reduction in the fuel or energy source consumed for a given output. Efficiency is one of the most frequently used terms in thermodynamics to assess the performance of a system, process, or application, and it indicates how well it functions or how well the goal is accomplished. However, efficiency is one of the most frequently misused terms in thermodynamics and often becomes a source of misunderstanding and misrepresentation. This is because efficiency is often used without being properly defined first. In this chapter, the relationships among efficiency and energy–exergy–environment are provided to show that an increased efficiency translates into a better environment and a more sustainable development.
