I have often pointed out the current debate that discusses which is more important, food security or energy independence. To ensure that there is enough biomass resources to address both food and fuel requirements, scientists are urging for more research to improve agricultural yield.

It is quite surprising that many of the issues that are relevant to the actual expansion of the ethanol industry is not being addressed by the government effectively. According to the director of the Nebraska Center for Energy Sciences at the University of Nebraska-lincoln Kenneth Cassman,

"It's the core issue to ensuring that we don't come up short in food supply, and don't have high consumer prices, and can still maintain expansion of the ethanol industry."

And he is right. The trick of the entire biofuels business is ensuring that neither food nor fuel is sacrificed but both are taken into very close consideration. Read more about this here.
