ABSTRACT
Sustainable energy ranks as one of the most signicant concerns of the twenty-rst century. e diminishing fossil fuel reserves, mounting crude oil prices, and intensifying threats of climatic variation have encouraged the present generation for the use of alternate energy sources for a balanced future (Stone 2006, 2011; Hepbasli 2008). One of the promising substitutes for fuels is nuclear energy, but recent disastrous events occurred at Chernobyl (Stone 2006) and Fukushima (Stone 2011) have forced the researchers to explore some other options for fuels. An alternate energy source, which can be relied upon in the present era, is bioenergy, owing to abundance of biological sources that promise to produce a good yield of energy. Biofuels can embrace a reduction of greenhouse gas emissions and also have a positive energy balance. It is established from various studies that extensive reduction in emission of greenhouse gases can be achieved by using ethanol as fuel made from sugarcane (Macedo et al. 2008). Additionally, bioenergy is also advantageous over combustion engines by presenting electrical vehicles.
