Ethanol.... some news
Posted: 21 Mar 2006, 20:20
Ethanol is usually made from crops (eg sugar cane, corn) or waste from crops. Its potential as a transport fuel is good. Today ethanol accounts for 40% of the fuel sold in Brazil.
The International Energy Agency has said that ethanol could make up as much as 10 percent of the world's petrol mix by 2025. Ref http://earth-policy.org/Updates/2005/Update49.htm
Recent reports from Brazil indicate that the price of sugar, a raw material for Ethanol production, will have to rise with this new demand. This year, sugar prices are at a 25 year high and Brazil is running short of Ethanol for its own transport fuels.
There are also issues of efficiency in the process of converting crops into fuel, relating to the fossil; fuels needed to grow and harvest the crops in the first place. Ref http://earth-policy.org/Updates/2005/Update49.htm
