Researchers at Purdue University have developed a model that shows how economic policies related to ethanol may impact future prices and production.
Purdue professor of agricultural economics Wally Tyner says the prices of corn and crude oil, which prior to 2007 fluctuated almost independent of one another, have become more closely linked as the use of corn to make ethanol has grown.
According to Tyner, the fixed 51-cent per gallon subsidy paid to ethanol producers will become increasingly expensive for the federal government as oil prices and levels of ethanol production continue to rise.
Tyner analyzed four policy options – the current 51-cent fixed subsidy, the variable subsidy, no subsidy and a renewable fuel standard – at oil prices ranging from $40 per barrel to $120 per barrel. The renewable fuel standard contained in the 2007 Energy Act mandates that energy companies purchase 35 billion gallons of ethanol by 2022, with a maximum of 15 billion gallons coming from corn.
“Regardless of the policy, results become similar at high crude oil prices where the market dominates,” Tyner said. “At low oil prices, however, government policies have huge effects, and all the results are enormously different. The policy choices we make will be critical.”





One hundred years after the original 1908 event designed to show the world how dependable automobiles could be, the 2008 Great Race will feature vehicles running on alternative fuels, such as biodiesel, ethanol, and even solar power.
This time around, the field will consist of a motley mix of vintage and new cars, including a 1904 Thomas Flyer and a 1941 Willys Jeep. They will rub fenders, metaphorically speaking, with various vehicles running alternative fuels — in an attempt to prove these new technologies by forging them in the crucible of a high-endurance test. Think Range Rovers on biodiesel, a multi-fuel-capable Aston Martin DB6 and a 2007 Buell Ulysses motorbike on E85 ethanol.
This is one of the most unique things I’ve seen in just more than a year of blogging for Domestic Fuel: a sports utility vehicle (SUV) that has its own biodiesel refinery in the back!
Officials at Penn State University say there has been no negative effects on tractors that they moved up to running on 100 percent biodiesel. The school started running its tractors on B20 in 2002 and more recently began testing three New Holland tractors (out of the 100 the school uses) on the B100.
A bill introduced in the Arizona legislature would help pay the costs of gas stations adding biofuels to their lineups.
Buses in the Monterey-Salinas, California area could soon be running on biodiesel made from mustard seeds. And what makes this idea even more intriguing is that the transit authority itself will be growing the alternative to the more conventional feedstocks, such as soybeans.
