Ethanol Industry Braces for Growing Pains.

WASHINGTON -- After a spurt of good fortune, the fledgling U.S. ethanol industry is anticipating some growing pains that could bring it unwanted attention this summer. Ethanol's public profile rose significantly for the better last July when Congress passed an energy bill that mandates the doubling of biofuels output by 2012. In January, President Bush gave the industry a further boost with a strong endorsement in his State of the Union speech. And with the imminent phaseout of a petrochemical added to gasoline to reduce tailpipe emissions, more U.S. motorists will depend on the corn-derived fuel than ever before.
