Howard T. Odum possessed one of the most innovative minds of the twentieth century. He pioneered the fields of ecological engineering, ecological economics, and environmental accounting, working throughout his life to better understand the interrelationships of energy, environment, and society and their importance to the well-being of humanity and the planet.

This volume is a major modernization of Odum's classic work on the significance of power and its role in society, bringing his approach and insight to a whole new generation of students and scholars. For this edition Odum refines his original theories and introduces two new measures: emergy and transformity. These concepts can be used to evaluate and compare systems and their transformation and use of resources by accounting for all the energies and materials that flow in and out and expressing them in equivalent ability to do work. Natural energies such as solar radiation and the cycling of water, carbon, nitrogen, and oxygen are diagrammed in terms of energy and emergy flow. Through this method Odum reveals the similarities between human economic and social systems and the ecosystems of the natural world. In the process, we discover that our survival and prosperity are regulated as much by the laws of energetics as are systems of the physical and chemical world.

A source book for American culture in the 1960s and 1970s: "suggested reading" from the Last Whole Earth Catalog, from Thoreau to James Baldwin. The Whole Earth Catalog was a cultural touchstone of the 1960s and 1970s. The iconic cover image of the Earth viewed from space made it one of the most recognizable books on bookstore shelves. Between 1968 and 1971, almost two million copies of its various editions were sold, and not just to commune-dwellers and hippies. Millions of mainstream readers turned to the Whole Earth Catalog for practical advice and intellectual stimulation, finding everything from a review of Buckminster Fuller to recommendations for juicers. This book offers selections from eighty texts from the nearly 1,000 items of "suggested reading" in the Last Whole Earth Catalog. After an introduction that provides background information on the catalog and its founder, Stewart Brand (interesting fact: Brand got his organizational skills from a stint in the Army), the book presents the texts arranged in nine sections that echo the sections of the Whole Earth Catalog itself. Enlightening juxtapositions abound. For example, "Understanding Whole Systems" maps the holistic terrain with writings by authors from Aldo Leopold to Herbert Simon; "Land Use" features selections from Thoreau's Walden and a report from the United Nations on new energy sources; "Craft" offers excerpts from The Book of Tea and The Illustrated Hassle-Free Make Your Own Clothes Book; "Community" includes Margaret Mead and James Baldwin's odd-couple collaboration, A Rap on Race. Together, these texts offer a sourcebook for the Whole Earth culture of the 1960s and 1970s in all its infinite variety.
