Adjunct Professor, Department of Ecology, Evolution, and Behavior, University of Minnesota. While technology eventually will limit these ratios, the ratio of energy input to the output of modern biofuel production is an important disadvantage to its widespread use. (Jan. 14, 2011)http://www.extension.purdue.edu/extmedia/ID/ID-346-W.pdf, Altieri, Miguel A. Biofuels are an alternative to fossil fuels (oil, natural gas, and coal). Biofuel is used to power vehicles, and is being produced by gasification in countries such as Sweden, Austria, and the . Looking for Renewable Energy Device & Equipment Prices? Biomass is plant or animal material like wood, energy crops, and waste from forests, farms, or yards utilized as fuel to generate electricity or heat. Biodiesel is a non-toxic fuel producing lower emissions as compared to fossil fuels when burnt. : Premium Gasoline Delivers Premium Benefits to Your Car. The process is not always cost-effective: Yes, though it may pay cash to the contributors, the truth is this process needs a lot of money, time and land to set up a plant and run.

Had it been the season's popular strain of corn, there could have been an ecological disaster as monarchs migrated through the corn-heavy American Midwest [source: Mellon and Rissler].

Or how animal fats, like whale oils, were used extensively in the 17th century to fuel lamps. Uses land that could be used to grow food. Compatibility refers to the ability of a fuel to be used in existing infrastructure and equipment without modification or damage. With the growth of the biofuel industry, more jobs will be created, which will help keep the economy secure. The action you just performed triggered the security solution. Because of the higher-than-petroleum gel point of many biodiesel-producing oils, a biodiesel engine can be difficult -- if not impossible -- to start in cold weather.
