Ethanol dazzles Wall Street, White House Ethanol production in the United States is growing so quickly that for the first time, farmers expect to sell as much corn this year to ethanol plants as they do overseas.

"It's the most stunning development in agricultural markets today — I can't think of anything else quite like this," says Keith Collins, the U.S. Agriculture Department's chief economist.

The amount of corn used for ethanol, estimated at 2.15 billion bushels this year, would amount to about 20 percent of the nation's entire crop, according to department projections.

Even as ethanol devours corn and pushes prices higher, the president and Congress are calling for even greater ethanol use. Wall Street cannot seem to get enough of ethanol-related investments. Automakers are speeding ethanol-capable vehicles onto the road.
