What kind of biofuels exist?
There are three major transport biofuels currently in production: ethanol, biodiesel and biogas. Ethanol is the longest established, with significant market share already in Brazil and a growing share in the United States, Europe and elsewhere. Biodiesel, made from combining methanol (or other alcohols) with vegetable oil, is a more recent development, and is found most predominantly in the European Union, where the transport mix is strongly biased towards diesel-powered engines (although development is ongoing elsewhere, including Brazil and Columbia). Biogas is least developed, with a market role at present only in Sweden. Research has also intensified into a commercially viable way of producing biobutanol, with production starting as soon as the end of 2007. In addition to these three primary biofuels, there are many other types of biofuels in existence. Find out more about biofuels.
