"Energy is the only universal currency. One of its many forms must be transformed into another in order for stars to shine, planets to rotate, living things to grow, and civilizations to evolve." "In this book, ecologist Vaclav Smil takes the principle of universality seriously, presenting a comprehensive and integrated survey of all the forms of energy that shape our world, from the sun to the human body, from bread to microchips. Each essay explains the science of the energy form as well as its implications for the functioning of the universe, life, or human society. Cross-links and summary diagrams allow easy comparisons among the various levels and flows of energy."--Jacket.
