Abstract

Fossil fuels have finite reserves. For example, oil has been projected to have already reached its peak capacity for production and may run out over the next several decades even at the current pace of use, i.e., not accounting for increased demand from China and India as their respective economies expand (Dhugga 2007). These concerns have intensified the debate on the potential of renewable fuels as supplements to fossil fuels. Biofuels, a collective term used to describe fuels derived from biological sources, offer a partial solution to the energy demand along with solar, wind, geothermal, and hydroelectric power.
