Wisconsin Bio Industry Alliance: New research shows higher energy efficiency for ethanol

MILWAUKEE – New research conducted at the University of Nebraska has demonstrated that ethanol has a much higher energy balance than previously estimated.

The university’s Nebraska Center for Energy Sciences Research found that ethanol production efficiency is actually two-three times more favorable than found in prior studies.

“While studies have always shown that ethanol has a positive energy balance, this new research shows just how efficient ethanol production really is,” said Joshua Morby, Executive Director of the Wisconsin Bio Industry Alliance (WBIA).  “Time and time again, studies have shown that ethanol is not only an efficient renewable fuel, but one that is better for the environment and reduces our dependence on foreign oil.”

Dr. Kenneth Cassman, the lead researcher on the study, said he estimates that for every one gallons of petroleum used in the ethanol production process, thirteen gallons of ethanol are produced. 

Cassman noted that previous research was done by evaluating older ethanol technologies, which have been surpassed by the technology currently used in most facilities.

The study has been submitted to the Journal of Industrial Ecology for publication.

The Wisconsin Bio Industry Alliance is a diverse group of businesses, environmental groups, and statewide and local organizations that have come together to build both public and legislative awareness of the Bio Industry in Wisconsin.
