another interesting article.
The 11-month rise of 50,000 barrels a day in U.S. gasoline demand (more than half the size of a 98,000 barrels a day rise a year ago) appears to be made up entirely of higher ethanol - rather than petroleum - content in the fuel.
Ron Planting, manager of information and analysis at the American Petroleum Institute, the Washington, D.C.-based trade group, said the volume of ethanol blended into gasoline supplied to the market was up, while the volume of petroleum in the fuel was down in 2007.
"Weak growth in gasoline demand, combined with the substantial increase in ethanol blending in 2007 resulted in the year's increase in gasoline supply coming entirely from ethanol," Planting said.
"Looking at either January-November or the full year, the increase in blended ethanol was larger than the rise in overall gasoline deliveries," he said. "My estimate is that ethanol blending increased about 90,000 barrels per day in 2007 over 2006.
Total domestic gasoline deliveries for the full year rose only about 35,000 barrels per day." Planting said API estimates that ethanol accounted for about 5% of the 9.287 million barrels a day of gasoline delivered in 2007, up from a 4% share of the 9.253 million barrels a day in 2006.
