this article is not only inaccurate but also poorly thought through. they only state that corn based ethanol will cause an increase in greenhouse gasses, yet they then brush that upon all biofuels. it has been known for years that corn based ethanol in the USA requires more energy input than is achieved as output when burned through a conventional petrol engine. the solution to that is using different feed stocks in production such as sugar cane, wheat or any other sugar producing crop. at the moment it is only corn based ethanol that is believed to be an inefficient use of energy, not all biofuels. Biodiesel can be made from just as many varied feed stocks with a significant improvement on energy output and far greater carbon dioxide capture rate than most bio-ethanol production processes.

greater thought needs to be put into articles about such important matters.
