In August 2012, the price of raw sugar was close to US$0.20 per pound while the price for ethanol was US$2.59 per gallon (US$0.68/L). More complete combustion making it a much cleaner exhaust than gasoline There are numerous sources for this fuel as long as it contains starch or sugar The sources of Ethanol consume carbon while growing and release that carbon when combusted making it a neutral carbon emitter and does not raise the atmospheric concentration of CO2 Disadvantages of Biofuels. For example, ethanol is in some instances sold in a price that is almost 30 cents lower than that of gasoline. It leads to biodiversity do to the fact that a large amount of arable land is required to grow these crops and could see some natural habitats destroyed including rainforests 2. Bioethanol suffers from another disadvantage in that it can degrade certain elastomers and corrode certain metals inside the vehicle, meaning that continual replacement is needed. The production of bioethanol from biomass or waste is one way to reduce both the consumption of crude oil and environmental pollution [11]. …Ethanol does burn cleaner than gasoline, which is another one of the advantages of ethanol fuel heavily promoted by its proponents. The primary disadvantage of ethanol is that it requires cropland space in which to grow. Algae might grow quickly, but it still needs time to produce viable oils. DISADVANTAGES. Advantages And Disadvantages Of Bioethanol Biofuel, energy produced from biomass offers the opportunity to reduce not just carbon dioxide (CO2) emissions but also the dependence from other states to import oil, and as well as to diversify the energy matrix (United Nations Organization for Food and Agriculture, 2008; Dagnino et al., 2013). The most important and widespread by the media is definitely the reduction of emissions: environmental officials estimate the use of sugarcane ethanol in Brazil has reduced the country's greenhouse gas emissions by 600 million metric tons . Despite the benefits, there are some disadvantages of biofuels that make the general population hesitant to use them. That's because bioethanol is a form of clean fuel that doesn't produce smoke, soot or ashes. Following this, the advantages and disadvantages of alternative fuels will be considered. There are some disadvantages to growing biofuel crops (such as sugar cane and maize) to be used as bioethanol: The demand for biofuel crops means greater demand on . Burning a liter of ethanol produces 34% less energy than burning a liter of petrol. Since bio-butanol is immiscible with water, it is less likely to contaminate the groundwater if it spills; while bio-ethanol is completely miscible with water and will cause water-pollution when it spills. The CO2 produced by burning ethanol is almost negligible, making these fireplaces an excellent option for those who want to go green. Advantages.
