We have been polluting our world too much. Naturally, we have tried to do something about it. What we use to create energy is the big problem, so people have tried to come up with a new, renewable energy source that is easily obtained. We have already figured out several non-polluting techniques: wind, water and solar power. But another attempt is not working out so well: ethanol. The problems start at the very beginning.

Most ethanol is made from corn. However, that corn must be supplied in enormous quantities, and corn is used in much food for humans and animals. If we use corn for fuel, more will need to be grown, on huge farms receiving government subsidies. We are paying extra so that our food can be used for fuel.

The corn is grown using chemical fertilizer, which is awful for the environment. Most pesticides are made from petroleum, exactly what ethanol is supposed to be preventing the use of. Also, the machinery on big farms needs massive quantities of gas.

The next step is even worse. The corn, grown with petrochemicals, must be distilled in factories to become ethanol. These factories need to get their energy from somewhere, and that somewhere is fossil fuels. It takes about nine-tenths of a gallon of fossil fuel to make a gallon of ethanol. Ethanol pollutes the environment about the same amount as if we just used fossil fuel.

To add insult to injury, ethanol is not as efficient as fossil fuel. In short, ethanol is stupid. It just doesn't do what it's supposed to do - namely, reduce our carbon footprint. Our government needs to start focusing its attention elsewhere. Wind, water and solar energy could use some boosting.
