International Society for the Advancement of Emergy Research

The Emergy Society
Welcome to the Emergy Society Web Site!

We are an international society dedicated to the
advancement of research on emergy and transformity
as a means to accomplish better decision-making in a
complex world. This work is accomplished within the
framework of Energy Systems Theory (Odum 1994).

Our goal is to support research and communication  
that will increase the quantity and improve the quality of
emergy research throughout the world.

You can explore our website to learn more about
emergy, H.T. Odum, and our organization.

A Prosperous Way Down Website and Blog

“A Prosperous Way Down” is a proposition that we can change our ways enough to gradually reduce our energy
use to fit the reduction of our resources.

The website,, created by Mary Odum Logan concentrates on this proposition. It supports
lively discussions on what we can do to fit the patterns of today and tomorrow.

The book ,
A Prosperous Way Down, by Howard T. Odum and Elisabeth C. Odum, was published in 2001 by
University Press of Colorado, 5589 Arapahoe Ave. Suite 206C, Boulder, Col. 80303.

A paper by Betty Odum summaries much of the book. The paper will be presented at a workshop at the Friends
General Conference, held at the University of Rhode Island July 1 - 7,  2012. You can download the paper by
following this link to
Betty's paper.

                             World Summit – Emergy Analysis for Designing a Prosperous and Sustainable Future

ISAER plans to run a broad-based conference to complement our biennial emergy research conference held at the University of Florida.
This international conference will be designed to appeal  to  a  wider  audience  including:  policy  makers,  government  officials, not-for-
profits and academics from a variety of disciplines interested in finding out more about emergy methods and their usefulness. A particular
emphasis would be on providing practical applications of emergy methods in real-world decision-making. Please go to the
Call for Proposals
