Developed from a proven course for advanced bachelor and graduate students and written in a readily accessible, didactic style, this compact treatment provides physics, chemistry, engineering and materials science students with the basics of energy and energy technology. It covers all important energy technologies based on depletable and renewable energy resources, including thermodynamics, energy from fossil and nuclear fuels and from renewables, energy transport, storage and fuel cells, examining the carbon footprint of different energy generation technologies. In addition, a chapter devoted to the Fukushima nuclear disaster and its consequences details how the nuclear power phase–out can be realized. A large number of problems and solutions at the end of each chapter are ideal training for exams and make self–study easy.
