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

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.
