Insane idea to take food and make it into fuel, AlGore now admits

GORE REGRETS: Corn ethanol 'was not good policy'...

ATHENS, Nov 22 (Reuters) - Former U.S. vice-president Al Gore said support for corn-based ethanol in the United States was "not a good policy", weeks before tax credits are up for renewal.

U.S. blending tax breaks for ethanol make it profitable for refiners to use the fuel even when it is more expensive than gasoline. The credits are up for renewal on Dec. 31.

"One of the reasons I made that mistake is that I paid particular attention to the farmers in my home state of Tennessee, and I had a certain fondness for the farmers in the state of Iowa because I was about to run for president."

U.S. ethanol is made by extracting sugar from corn, an energy-intensive process. The U.S. ethanol industry will consume about 41 percent of the U.S. corn crop this year, or 15 percent of the global corn crop, according to Goldman Sachs analysts.

A food-versus-fuel debate erupted in 2008, in the wake of record food prices, where the biofuel industry was criticised for helping stoke food prices.
