Acknowledgments
We would like to acknowledge the help of our reviewers in refining the information available here.
Specifically we would like to thank Robert Kaufmann for his insights into extrapolating EROI into the
future. We would also like to thank the members of the SUNY ESF research team for undertaking the
task of accumulating much of this scarce information. The original results are reported in The Oil
Drum website (www.theoildrum.com) and in a summary by Richard Heinberg. Finally we would like
to thank the Santa-Barbara Family Foundation for providing the funding for that research, and the UK
Department for International Development (DFID) and Tullet Prebon for recent support.
