A profound understanding of the physical laws underlying energy converters is a prerequisite for a sustainable use of our energy resources.

The aim of this textbook is to provide a unified view on the different energy conversion processes ranging from power plants to solar cells. It offers an interdisciplinary introduction to energy sciences for senior undergraduate and graduate students from natural sciences and engineering. The central theme is the treatment of energy converters as open thermodynamical systems and the performance of efficiency analyses, based on the concept of exergy.

• Presents the physics behind the most important energy converters in a unified framework.
• Evaluates the performance of ideal and realistic energy converters in terms of energy and exergy efficiencies
• Provides basic concepts needed for a discussion of energy converters, such as chemical and applied thermodynamics, electrochemistry and solid state physics.
