As a mouthpiece for the ethanol industry, Gov. Matt Blunt made a big mistake last week: He underestimated the intelligence of Missourians.

In an audacious press release, Blunt touted a new study that showed the state's drivers were allegedly saving money by using a 10 percent ethanol blend of gasoline.

But the new study that Blunt embraced was fatally flawed.

Fact: Gasoline blended with ethanol delivers less energy than normal gasoline. In other words, ethanol-blended fuel delivers fewer miles to the gallon.

National experts peg the mileage reduction at around 3 percent a gallon.

In other words, ethanol-blended fuel has to be about 3 percent cheaper than normal gasoline to produce the same mileage.

The study was done by John Urbanchuk, director of LECG, a consulting firm in Wayne, Pa. He told the newspaper that the loss of energy by using ethanol was insignificant.

But as The Star's Steve Everly wrote, "At current pricing, though, that energy loss more than wipes out the savings that the study says consumers will reap by using ehanol-blended fuel."

It would be nice if Blunt issued a mea culpa for being so easily misled by the ethanol industry. Don't count on it, though.
