"With work and luck, ethanol could displace imported petroleum. Will it help break the U.S. addiction to oil?"

"Even studies by ethanol fans concede that achieving energy independence via ethanol requires bullish assumptions. Among them: that refiners will get at least twice as good at making ethanol. That the average efficiency of U.S. vehicles improves to 42 miles per gallon, 68% better than the 25mpg now achieved. And that people will move closer to where they work.
