COLLOQUIUM: History, Applications, Numerical Values and Problems with the Calculation of EROI - Energy Return on (Energy) Investment

Professor Charles Hall
State University of NY College of Environmental Science and Forestry

Plants and animals are subjected to fierce selective pressure to do the “right thing” energetically, that is to insure that whatever major activity that they did, and do, gained more energy than it cost. It is obvious that a cheetah, for example, has to catch more energy in its prey than it takes to stalk it and successfully run it down, and considerably more to make it through lean times and to reproduce.  

Likewise, it is imperative that we have some good and consistent way of thinking about the energy profit of various fuels. Energy Return on Investment (EROI or sometimes EROEI) offers the possibility of a very useful approach for looking at the advantages and disadvantages of fuels and offers the possibility of looking into the future in a way that markets seem unable to do. Its advocates also believe that, in time, market prices must approximately reflect comprehensive EROIs, at least if appropriate corrections for quality are made and subsidies removed. This seminar summarizes research on EROI including time series for our most important fuels, while discussing problems and remaining issues with the calculations. Finally, it discusses the relation of EROI to economies including the minimum EROI required for civilization as we know it.
