* Book: Energy and the Wealth of Nations. Understanding the Biophysical Economy. By Charles A.S. Hall and Kent Klitgaard.


"For the past 150 years, economics has been treated as a social science in which economies are modeled as a circular flow of income between producers and consumers. In this “perpetual motion” of interactions between firms that produce and households that consume, little or no accounting is given of the flow of energy and materials from the environment and back again. In the standard economic model, energy and matter are completely recycled in these transactions, and economic activity is seemingly exempt from the Second Law of Thermodynamics. As we enter the second half of the age of oil, and as energy supplies and the environmental impacts of energy production and consumption become major issues on the world stage, this exemption appears illusory at best.

In Energy and the Wealth of Nations, concepts such as energy return on investment (EROI) provide powerful insights into the real balance sheets that drive our “petroleum economy.” Hall and Klitgaard explore the relation between energy and the wealth explosion of the 20th century, the failure of markets to recognize or efficiently allocate diminishing resources, the economic consequences of peak oil, the EROI for finding and exploiting new oil fields, and whether alternative energy technologies such as wind and solar power meet the minimum EROI requirements needed to run our society as we know it. This book is an essential read for all scientists and economists who have recognized the urgent need for a more scientific, unified approach to economics in an energy-constrained world, and serves as an ideal teaching text for the growing number of courses, such as the authors’ own, on the role of energy in society."

"In this, the first episode of From Alpha To Omega, I interview Dr. Charles A.S. Hall co-author of the new book 'Energy & The Wealth Of Nations - Understanding the Biophysical Economy'. We talk about the origins of wealth, empire, the intellectual horror-scape that is neo-classical economics, peak-oil, and the limits to growth. I also give a brief outline on the philosophy of the podcast, with a nod to the wise sage that is Noam Chomsky."
