The Myths of Biofuels with David Fridley
by Michael Levy, Local Solutions for Global Problems
Americans eat up our body weight in petroleum once each week, as a result of our strange proclivity for driving everywhere—a third of all car trips in the U.S., for example, are under three miles. Nonetheless, pointing out the obvious idea that we need to largely stop driving and flying in order to address global warming and a whole host of other problems is a sure way to become unpopular, fast. It seems easier for most people to consider a change of technology—even at some financial cost—than a change of lifestyle.
During the past year I've had conversations with friends—many of them environmentalists—who enthusiastically respond with the promise of cars running on hydrogen, electricity, compressed air, and of course, biofuels in forms such as used restaurant fry oil, biodiesel, and ethanol. I haven't won points by explaining that none of these technologies are likely to rescue our climate the way that getting out of our cars would.
Biofuels seem to be a particularly alluring proposal as a solution to the problems associated with fossil fuels. It seems "eco" to recycle restaurant grease, and it's appealing to think that the carbon dioxide generated by burning biofuel will be absorbed by the next crop of corn or switchgrass. In fact, you can do some good this way. San Francisco, for example, has embarked on an ambitious program to run its city vehicles partially on recycled restaurant grease, which otherwise clogs the city's sewers. This is a nice thing. But it's a tiny thing—and it should stay that way. Biofuels are simply no match for the immense quantity of fossil fuel energy we consume. Each year we use up about 4,000 years of prehistoric plant growth in the form of fossil fuels. Put another way, according to one estimate, we in the U.S. use more fossil fuel energy than the amount of solar energy captured by every growing plant over our entire land area.
The U.S. government and E.U. are working against this problem of scale and embarking upon programs of massive biofuel reliance. This is ultimately not a solution, and scale is only one of many problems with large-scale biofuel production. Among other issues is the humanitarian disaster that production of biofuels is already creating. Growing large amounts of corn, soybeans, and canola for fuel has already driven the price of these and other food crops through the roof. This past year, corn prices have increased by 50%, while wheat has doubled, in part because land is being used for fuel production instead of food. This hits poor countries hard. The situation is serious enough for Jean Ziegler, U.N. rapporteur on food issues, to call biofuel production a "crime against humanity," and call for a five-year moratorium.
There are also significant ecological drawbacks of trying to fill our voracious appetite for fuel by growing plants. For example, to fill the European demand for biodiesel, Indonesia has cleared millions of hectares of forest to plant oil palm. The resulting emissions from exposed peat soils and burned trees have earned Indonesia the distinction of being the third-largest greenhousegas- emitting nation in the world.
There are many more interesting facts to learn about biofuels. With wanton disregard for our social standing, members of People Power's Local Solutions Committee are hosting a talk on the Myths of Biofuels, with David Fridley, energy researcher from Lawrence Berkeley Labs. Beyond pointing out what won't work, the evening promises to point us in a positive direction, as Micah and Joe Jordan follow up with a discussion of a realistic plan for local energy independence. We hope to see you there.
