But that's not to say the home-grown fuel is being produced without opposition.
While proponents boast of ethanol's economic influence on the rural economy, critics question the subsidies it receives and its impact on the environment.
But opponents of ethanol believe differently. Outspoken expert Dr. David Pimentel, a staunch opponent of all things ethanol, believes the water use is higher than UNL officials believe. Pimentel, whose studies have been discredited by several scientists including some who work for USDA, puts the number closer to 15 gallons of water for every single gallon of ethanol produced.
And butanol, one of ethanol's renewable competitors, may have received a setback on its road to commercialization. In 2006, along with its limited partner DuPont, BP announced a possible release date for the biofuel of sometime in 2007 but BP announced a new target sometime in 2009.
Butanol appeals to many renewable fuels proponents because of its advantages over ethanol. According to scientists, the biofuel can be made from the same natural products as ethanol, pumped through pipelines, and deliver almost 80% of the power found in regular gasoline. Studies have revealed ethanol only produces 60 percent of the power in its petroleum-based counterpart and might cause corrosion in older pipelines.
