Finding alternatives for traditional, nonrenewable feedstocks has become more necessary recently. Traditionally, a great deal of the feedstocks used were petroleum-based, and this has posed a problem because it is a resource that is not in unlimited supply. Finding possible alternative, renewable feedstocks provide many benefits. It could end the dependence upon foreign oil, and if we are able to find something that we can produce in this country, it could be a serious boost to the economy if we were able to create an entire new industry out of this.
One example of a renewable feedstock that has become very popular over the past few years is corn. Corn is used in ethanol, which is an alternative fuel. Ethanol is more efficient than gasoline, cheaper to produce, and can be used in any engine. All of these make it something that should become much more popular in upcoming years. Ethanol also does not have the potential to cause health problems like gasoline does, and has even been endorsed by the American Lung Association as a green alternative to gasoline. Awareness of such problems with nonrenewable resources should also be spread because as much progress as has been made on green issues in the past few years, public awareness of exactly how much of a problem we have is still a bit lacking.
