Yes, ethanol can be very useful as fuel. It could reduce our consumption of gasoline. But corn ethanol isn't the answer. If we are to use biofuel, then we need to choose a more efficient type of ethanol.

It is becoming more and more obvious that we need to move away from oil as a major source of fuel. The problem is that we are obviously and pathetically hooked on it. Nearly every middle-class American has considered taking the car to the corner store as opposed to walking. Although it is great that we've found a way to reduce oil consumption in cars with biofuels, we need to make sure that we're making the right decisions.
Corn ethanol, the biofuel receiving the most support from the U.S. government, is a bad substitute for gas. In fact, corn ethanol provides not more than a 3% reduction of greenhouse gas emissions, whereas sugar cane ethanol and celluslosic ethanol, respectively, provide a 50%-70% and more than 90% reduction in greenhouse gas emissions. As it turns out, corn ethanol is not very 'green.'
Yes, ethanol can be very useful as fuel. It could reduce our consumption of gasoline. Experts agree that ethanol is energy efficient. But corn ethanol isn't the answer. If we are to use biofuel, then we need to choose a more efficient type of ethanol. However, we need to choose wisely because with the help of biofuels food prices are soaring. Biofuels should only be a means to an end, not a permanent solution. The only way to create a system that can last is to eliminate the use of oil.
