This is a fascinating book. It provides a comprehensive and integrated survey of the energies shaping our world. It is filled with diagrams, graphs, maps, drawings and photographs to support the text. This book can't be described. It has to be experienced: energy production of the sun, global patterns of latent heat flux, a horse's suspensory and check ligaments that allow it to use hardly any additional energy for standing, preindustrial societies, cars and computers and much more. Use this book for reference and for browsing. Spend an afternoon with a calculator and the figures listed in the tables in this book. You will begin to appreciate the complex relationships involving the energies that shape our world.
