Clearly the development and use of biofuels was a road of good intentions, it has just been pushed in a different way. Biofuels, like fuels, now have corporate constituents and players who like their consumption of raw materials as it keeps their demand where they want it to be. It's no secret that automobile companies bought and dismantled public transport to gain marketshare and drive people to spend their dollars. Though creating ethanol from corn is not efficient, the ag lobby will not allow this to be curtailed in the short term as it inflates corn prices in the US. The plus side is that, at least, having developed some refining technologies and basic knowledge; we should be able to advance quickly once the technology is available to create cellulosic ethanol from saw grass or algae.
