Starving for gas?

CARS, NOT PEOPLE, will claim most of the increase in world grain consumption this year. The U.S. Department of Agriculture projects that world grain use will grow by twenty million tons in 2006. Of this, fourteen million tons will be used to produce fuel for cars in the United States, leaving only six million tons to satisfy the world's growing food needs.

In agricultural terms, the world appetite for automotive fuel is insatiable. The grain required to fill a twenty-five gallon SUV gas tank with ethanol will feed one person for a year. The grain to fill the tank every two weeks over a year will feed twenty-six people in that same period.

Investors are jumping on the highly profitable biofuel-bandwagon so fast that hardly a day goes by without another ethanol distillery or biodiesel refinery being announced somewhere in the world. The amount of corn used in U.S. ethanol distilleries has tripled in five years, jumping from eighteen million tons in 2001 to an estimated fifty-five million tons from the 2006 crop.

In some U.S. Corn Belt states, ethanol distilleries are taking over the corn supply. In Iowa, a staggering fifty-five ethanol plants are operating or have been proposed. Iowa State University economist Bob Wisner observes that if all these plants are built, they would use virtually all the corn grown in Iowa. In South Dakota, one of the top-ten corn-growing states, ethanol distilleries are already claiming over half of the corn harvest.

With so many distilleries being built, livestock and poultry producers fear there may not be enough corn to produce meat, milk, and eggs. And since the United States supplies 70 percent of world corn exports, corn-importing countries are worried about their supply.

Since almost everything we eat can be converted into fuel for automobiles, including wheat, corn, rice, soybeans, and sugarcane, the line between the food and energy economies is disappearing. Historically, food processors and livestock producers that converted these farm commodities into products for supermarket shelves were the only buyers. Now there is another group, those buying for the ethanol distilleries and biodiesel refineries that supply service stations.

As the price of oil climbs, it becomes increasingly profitable to convert farm commodities into automotive fuel, either ethanol or biodiesel. In effect, the price of oil becomes the support price for food commodities. Whenever the food value of a commodity drops below its fuel value, the market will convert it into fuel.

Crop-based fuel production is now concentrated in Brazil, the United States, and Western Europe. The United States and Brazil each produced over four billion gallons (sixteen billion liters) of ethanol in 2005. While Brazil uses sugarcane as the feedstock, U.S. distillers use grain--mostly corn. The fifty-five million tons of U.S. corn going into ethanol this year represent nearly one sixth of the country's grain harvest but will supply only 3 percent of its automotive fuel.

Brazil, the world's largest sugar producer and exporter, is now converting half of its sugar harvest into fuel ethanol. With just 10 percent of the world's sugar harvest going into ethanol, the price of sugar has doubled. Cheap sugar may now be history.

In Europe the emphasis is on producing biodiesel. Last year the European Union (EU) produced 1.6 billion gallons of biofuels. Of this, 858 million gallons were biodiesel, produced from vegetable oil, mostly in Germany and France, and 718 million gallons were ethanol, most of it distilled from grain in France, Spain, and Germany. Margarine manufacturers, struggling to compete with subsidized biodiesel refineries, have asked the European Parliament for help.

In Asia, China and India are both building ethanol distilleries. In 2005 China converted some two million tons of grain--mostly corn, but also some wheat and rice--into ethanol. In India ethanol is produced largely from sugarcane. Thailand is concentrating on ethanol from cassava, while Malaysia and Indonesia are investing heavily in additional palm oil plantations and in new biodiesel refineries. Within the last year or so, Malaysia has approved thirty-two biodiesel refineries, but has recently suspended further licensing while it assesses the adequacy of palm oil supplies.

The profitability of crop-based fuel production has created an investment juggernaut. With a U.S. ethanol subsidy of 51 cents per gallon in effect until 2010, and with oil priced at $70 per barrel, distilling fuel alcohol from corn promises huge profits for years to come.

In May 2005 the one hundredth U.S. ethanol distillery came on line. Seven of these distilleries are being expanded. Another thirty-four or so are under construction and scores more are in the planning stages. The soaring demand for crop-based fuel is coming when world grain stocks are at the lowest level in thirty-four years and when there are seventy-six million more people to feed each year.

The U.S. investment in biofuel production in response to runaway oil prices is spiraling out of control, threatening to draw grain away from the production of beef, pork, poultry, milk, and eggs. And, most seriously, the vast number of distilleries in operation, under construction, and in the planning stages threatens to reduce grain available for direct human consumption. Simply put, the stage is being set for a head-on collision between the world's 800 million affluent automobile owners and food consumers. Given the insatiable appetite of cars for fuel, higher grain prices appear inevitable. The only question is when food prices will rise and by how much. Indeed, in recent months, wheat and corn prices have risen by one fifth.

For the two billion poorest people in the world, many of whom spend half or more of their income on food, rising grain prices can quickly become life threatening. The broader risk is that rising food prices could spread hunger and generate political instability in low-income countries that import grain, such as Indonesia, Egypt, Nigeria, and Mexico. This instability could in turn disrupt global economic progress. If ethanol distillery demand for grain continues its explosive growth, driving grain prices to dangerous highs, the U.S. government may have to intervene in the unfolding global conflict over food between affluent motorists and low-income consumers.

There are alternatives to using food-based fuels. For example, the equivalent of the 3 percent gain in automotive fuel supplies from ethanol could be achieved several times over--and at a fraction of the cost--simply by raising auto fuel efficiency standards by 20 percent. Investing in public transport could reduce overall dependence on cars.

There are other fuel options as well. While there are no alternatives to food for people, there is an alternative source of fuel for cars, one that involves shifting to highly efficient gas-electric hybrid plug-ins. This would enable motorists to do short-distance driving, such as the daily commute, with electricity. If wind-rich countries such as the United States, China, and those in Europe invest heavily in wind farms to feed cheap electricity into the grid, cars could run primarily on wind energy, and at the gasoline equivalent of less than $1 a gallon.
