Alternative Fuels

One new and upcoming fuel source that is being developed and used is the production of Bioethanol. This is a renewable form of ethanol that can be made from agricultural products such as corn, sugar cane, and potatoes. There are a lot of upsides to this fuel. There are some concerns however. The fuel is renewable source and considered "green." Some of the downsides and cons associated with this fuel are the increase in food cost. If crops were to start being used for fuel as well as food then the demand for these crops would rise and probably drive up the costs. There is also a concern for the balance or energy and pollution that comes with the production of bioethanol. Another con is that this process can have excess wastes that are largely useless. There is research being done into uses for the waste. One example of this is using different types of grasses to make the fuel and then using the waste produced to make things like paper.
