The New Petroleum
Senator Richard G. Lugar (R-Ind.) is the Chairman of the Agriculture, Nutrition, and Forestry Committee and a member of the Foreign Relations Committee. R. James Woolsey, an attorney, was Director of Central Intelligence from 1993 to 1995. He serves on the boards of several corporations, including BC International, which is expected to open the first commercial biomass ethanol plant in the United States in 2000.See more by Richard G.

Oil is a magnet for conflict. The problem is simple -- everyone needs energy, but the sources of the world's transportation fuel are concentrated in relatively few countries. Well over two-thirds of the world's remaining oil reserves lie in the Middle East (including the Caspian basin), leaving the rest of the world dependent on the region's collection of predators and vulnerable autocrats. This unwelcome dependence keeps U.S. military forces tied to the Persian Gulf, forces foreign policy compromises, and sinks many developing nations into staggering debt as they struggle to pay for expensive dollar-denominated oil with lower-priced commodities and agricultural products. In addition, oil causes environmental conflict. The possibility that greenhouse gases will lead to catastrophic climate change is substantially increased by the 40 million barrels of oil burned every day by vehicles.
Ethanol has always provided an alternative to gasoline. In terms of environmental impact and fuel efficiency, its advantages over gasoline substantially outweigh its few disadvantages. But until now it has only been practical to produce ethanol from a tiny portion of plant life -- the edible parts of corn or other feed grains. Corn prices have fluctuated around $100 a ton in the last few years, ranging from half to double that amount. Ethanol has thus been too expensive to represent anything but a small, subsidized niche of the transportation fuel market. In spite of recent reductions in the expense of ethanol processing, the final product still costs roughly a dollar a gallon, or about double today's wholesale price of gasoline.
Recent and prospective breakthroughs in genetic engineering and processing, however, are radically changing the viability of ethanol as a transportation fuel. New biocatalysts -- genetically engineered enzymes, yeasts, and bacteria -- are making it possible to use virtually any plant or plant product (known as cellulosic biomass) to produce ethanol. This may decisively reduce cost -- to the point where petroleum products would face vigorous competition.
