Oh Snap! Now some German scientists have (in effect) taken a swing at Stanford professor Mark Z. Jacobson, who concluded in a recent paper that biofuels are a bad policy direction (see summary post here).
In their paper Sustainable global energy supply based on lignocellulosic biomass from afforestation of degraded areas, Prof. Jürgen O. Metzger from Carl von Ossietzky University of Oldenburg in Germany and Prof. Aloys Huettermann from the University of Goettingen in Germany say that growing and using biofuels for all the earth’s energy needs is not only possible without jeopardizing the global food supply, but also economically feasible.
Their key discovery is that by reforesting land that has been “degraded by human use in historical times”, they found:
… the global energy demand projected by the International Energy Agency in the Reference Scenario for the year 2030 could be provided sustainably and economically primarily from lignocellulosic biomass grown on areas which have been degraded by human activities in historical times.
