Patzek, T. W., “How Can We Outlive Our Way of Life?” Paper prepared for the Ministerial OECD Round Table on Sustainable Development, “Biofuels: Is the Cure Worse than the Disease?” OECD Headquarters, Chȃteau de la Muette, 2 rue Andre Pascal, 75016 Paris, September 12, 2007
In this paper I outline the rational, science-based arguments that question current wisdom of replacing fossil plant fuels (coal, oil and natural gas) with fresh plant agrofuels. This 1:1 replacement is absolutely impossible for more than a few years, because of the ways the planet Earth works and maintains life. After these few years, the denuded Earth will be a different planet, hostile to human life. I argue that with the current set of objective constraints a continuous stable solution to human life cannot exist in the near-future, unless we all rapidly implement much more limited ways of using the Earth’s resources, while reducing the global populations of cars, trucks, livestock and, eventually, also humans. To avoid economic and ecological disasters, I recommend to decrease all automotive fuel use in Europe by up to 6 percent per year in 8 years, while switching to the increasingly rechargeable hybrid and all-electric cars, progressively driven by photovoltaic cells. The actual schedule of the rate of decrease should also depend on the exigencies of greenhouse gas abatement. The photovoltaic cell-battery-electric motor system is some 100 times more efficient than major agrofuel systems.
