As our authors advise, however, we shouldn't throw out the jatropha, French-fry grease and pond scum with the maize. Corn is but one of numerous feedstocks that can be used to produce biofuel, and fermentation, the process used to make it, is but one of a handful of technologies available to us.
University of Waterloo's Kyrke Gaudreau evaluates a range of feedstocks and a variety of processes by analyzing their effect on our ecosystem. "If we are to successfully shift from a petroleum-based energy system to a biological one," he warns, "we need to look at the forest as well as the trees."
Gaudreau finds fault with fermentation, a discovery that complements what Washington State University's energy experts point out in "How Much Energy Does it Take to Produce a Litre of Biofuel?"
