Biofuels

"Bio-fuels are sources of energy that come from living, renewable sources, such as corn, palm oil, and even animal manure. In recent years bio-fuels have come to mean fuels such as ethanol and bio-diesel, which can be burned in engines to drive vehicles in place of fossil fuels like petroleum and diesel fuel. Bio-fuels have also been promoted as a way of reducing carbon emissions and thus tackling global climate change. More than 40 countries now offer some sort of subsidy to encourage the production and use of bio-fuels instead of fossil fuels. This topic looks at whether bio-fuels really are better than fossil fuels, and whether governments should continue to develop policies to promote bio-fuel production and use." (The Debatabase Book)
