Energy and the Global Environment provides an up-to-date introduction to the subject examining the relationship between energy and our global environment. Energy is placed at the front of a discussion of geo-systems, living systems, technological development and the global environment, enabling the reader to develop a deeper understanding of magnitudes. Learning is re-enforced, and the relevance of the topic broadened, through the use of several conceptual veins running through the book. One of these is an attempt to demonstrate how systems are related to each other through energy and energy flows. Examples being wind-power, and bio-mass which are really solar power via another route; how theenergy used to evaporate sea water must be related to the potential for hydropower; and where a volcano's energy really comes from. With fermi-like problems and student exercises incorporated throughout every chapter, this text will provide the perfect companion to the growing number of students taking an interest in the subject.
