Ethanol production yields about the same pounds of carbon dioxide as pounds of ethanol (and about the same pounds of high quality animal feed). I was wondering how long it would taking carbon pimps to admit this.
People knew that ethanol was inefficient and a drag to food supplies 5 years ago.
A study done at Cornell University in 2005 said the following:
“Turning plants such as corn, soybeans and sunflowers into fuel uses much more energy than the resulting ethanol or biodiesel generates, according to a new Cornell University and University of California-Berkeley study.
“There is just no energy benefit to using plant biomass for liquid fuel,” says David Pimentel, professor of ecology and agriculture at Cornell. “These strategies are not sustainable...”
“Ethanol production in the United States does not benefit the nation’s energy security, its agriculture, economy or the environment,” says Pimentel. “Ethanol production requires large fossil energy input, and therefore, it is contributing to oil and natural gas imports and U.S. deficits.” He says the country should instead focus its efforts on producing electrical energy from photovoltaic cells, wind power and burning biomass and producing fuel from hydrogen conversion. “
