Dan Walters thinks ethanol gets a bad wrap energywise and he's got numbers to prove it.

Grain-based ethanol is a cleaner-burning, renewable alternative to fossil fuels. But critics cite studies showing ethanol production uses more energy than it produces.

"The problem is that's all old data," said Walters, a University of Nebraska-Lincoln soil scientist. Such studies are based on figures from the late 1980s and early 1990s, yet much has changed in agriculture and ethanol production in the past decade.
