Introduction
Biofuels can be generated through the bioconversion of substrates found in agricultural residues. These agricultural residues can be converted to ethanol by a variety of yeasts such as Saccharomyces cerevisiae and Zymomonas mobilis through the bioconversion of the sugars of the residues. (Drapcho,C. M ,et.al, 2008). (Drapcho, 2008) The research focuses particularly on sweet potato peels, an agricultural residue to produce bioethanol through fermentation with the use of Saccharomyces cerevisiae (yeast). Furthermore, the research also focuses on finding a way for the produced bioethanol to have a higher percent yield in order to avoid higher production cost in the process. In maximizing the use of the sweet potato peels in the bioethanol fuel production, conservation of natural resources such as syngas and methane gas will be manifested which will lead to the reduction of pollution due to the less harmful effect of the product of bioethanol’s combustion to the environment. The bioethanol produced in the process can be used as an alternative fuel source for the machineries like tilling trucks in the plantation. The sweet potato peels that will be used in the course of the study will be from Mabalacat, Pampanga because of its high production status. The people who will benefit the study are the farmers of Mabalacat, Pampanga who grow the sweet potatoes, the residents of Mabalacat, Pampanga who will be alleviated from the foul smell of the decomposing peels, and the sweet potato industry specifically known for a macroscopic production of sweet potato resources.

Statement of the Problem
The relentlessly rising costs of oil, which exceeded $70 per barrel in 2006, and which in inflation-adjusted terms is approaching the all-time high of the mid-1970s, now poses a major brake on industrializing efforts by developing countries. The price is one effect; the other is the possibility of being held to ransom by either Middle Eastern oil regimes or by oil companies looking to allocate ever scarcer supplies. The Middle East has reached the limit of its capacity, and is already embarked on an inexorable decline. The immediate impact will be that Saudi Arabia will no longer be able to play the role of swing producer – producer of last resort. Non-conventional sources of oil and gas – such as tar sands -- will simply not be able to pick up the slack, because of high costs, or technical difficulties, or political resistance, as in the case of drilling in Arctic areas. Thus there is no alternative to renewable energy options, especially for developing countries where rising oil import prices would wreck industrialization plans. (Matthews, 2006)

These problems are only a few on the dependence of countries to oil production. Production and usage of countries in fossil fuels, not only costs a lot of money but also produce higher carbon emission and environmental problems that many people are concerned. Greenhouse gases and carbon emissions from fossil fuels produce more on the climate change. These gases contribute to the change of weather patterns of the world. Stronger typhoons and hurricanes will be produced by the production of these gases. Higher consumption of developed countries of crude oil worsens the natural cycle of the environment and its ecology. As the need for oil production is going beyond its capacity. The prices also rise into a considerable amount. Oil prices are going beyond the usual prices because of its low supply and high demand in the market. As higher prices of oil are made into the global market, local consumers of countries, especially in the Philippines are affected. Higher oil prices, means higher gasoline and diesel prices, higher prices of food products, and higher electricity bills. The country’s dependence on oil has provoked local scientists to not only produce alternative fuels for the usage of the consumers, but also to promote environmental awareness in the country.
