of our take - home messages is that conservation programs are currently a cheaper and
more efficient greenhouse gas policy for taxpayers than corn -
ethanol production,» said study leader and Duke biologist Robert Jackson.
But all
of this is despite serious scientific concerns about biofuels, especially corn
ethanol - whose
production requires lots
of land, and consumes lots
of energy - some say
more than the fuel itself produces.
Throw in
more competition for these same crops due to an increase in
ethanol production and you have a recipe for higher gas prices, higher food prices and even possibly shortages
of one, the other, or both.
The US has now crossed the point where

ethanol production than for feeding people producing 206.5 million barrels
of ethanol in 2010.
Bloomberg Businessweek explains
more clearly than EPA does why the agency had to back - peddle so furiously: «The Environmental Protection Agency proposed requiring less cellulosic
ethanol to be blended into gasoline next year than sought under U.S. law because
production of the alternative fuel hasn't reached commercial scale.»
They say the technological fixes also distract from
more challenging social reforms like slowing the rate
of population growth, shifting away from crops like corn
ethanol that don't put food on the table, or ending subsidies for livestock
production, which currently eats up an appalling 75 percent
of the world's agricultural land.
This summer, expensive and rare corn has left 26

When we assume the
ethanol production process is fully renewable, it would take all the corn in the country to displace about 3.5 percent
of our gasoline consumption — only slightly
more than we could displace by making sure drivers» tires are inflated properly.
While industrial
production of ethanol may not be the savior as it was once heralded, home distillers are willing to tap into a
more parochial form
of energy independence.
In years where we have a bumper crop
of corn, and produce
more than we need for feed, the market to distilleries will provide built in price supports; the DDGS from the other
