On this site we typically discuss the extent and timing of our energy supply limits, (as well as planetary sink capacities and non-energy input limits). Less common are discussions on our ends, and whether our current trajectory is mentally/physically sustainable irrespective of source/sink constraints on the horizon. Tonight's Campfire questions will relate to demand limits to growth in the hypothetical situation of unlimited resources. Perhaps from a perspective of infinite abundance we might gain insight on how best to address resource shortages.

Much of what we discuss at theoildrum is about supply - pinpointing problems and/or advantages of existing and future energy technologies. These are the 'means' by which society meets its day to day demands. But little time, (and certainly not equal time) is devoted to discussing the 'ends' - what is all this energy for. As many of you know, I am completing my Phd in Natural Resources at The University of Vermont, with a specialization in Ecological Economics. This hybrid field asserts that the economy is just a part of a larger planetary system (as opposed to the planet and its resources being just part of the economy). EE attempts to evaluate (monetarily and otherwise) the things the market system takes for granted (fresh air and water, biodiversity, healthy dolphin populations, stable climate, etc.) But a growing subset of ecological economists are addressing the 'ends'. By digging into the empirical datapoints that comprise human happiness, we are finding we can be happier with far less energy use. I initially wrote about this here. Below is a short essay, also posted on Grist, co-authored by my advisor Robert Costanza. In my opinion, the questions these authors raise should be preceding or at least accompanying policy discussions on how we decide to obtain and allocate more energy. Ends before means.

This article explores dynamic relations governing population growth, resource depletion, and world economics by means of a few simple modeling and simulation exercises. To this end, we start out by exploring the concept of an ecological footprint, representing the amount of land that a person needs to produce everything that he or she consumes: food, clothing, energy, shelter, the tools that are needed to make the clothing, etc. and place it in relation with the human development index, a measure of the quality of life of an individual. We then relate the ecological footprint to the per capita energy consumption. This discussion serves to provide a quantitative understanding of the limited resources that are at our disposal.

The article continues by exploring the dangers and seductions of exponential growth, and uses a system dynamics approach to illustrate why we are moving at a rapid pace toward global collapse with our eyes wide shut.

The article ends by discussing what we would need to do in order to avoid the looming collapse.
