Yes, corn ethanol is a good way to reduce oil use and dependence, because it is something that we can grow more of. Natural resources, such as the weather, and renewable resources are the future in energy. The more corn ethanol is used, the less we will be dependent on fossil fuels.
Corn ethanol is destructive to the environment. It takes away important land from other crops and most corn is genetically modified. Other crops could be grown on the land that the corn used for corn ethanol is grown on. Better ways to reduce oil use and dependence involve researching and looking into other forms of energy, such as solar and wind.
