Aside from that, biodiesel is more expensive because it can be costly to produce and the supply is still low. The elephant in the living room that is often ignored when considering energy options, however, is the hard reality that we must reduce our consumption, not just replace it with something else. Postal Service, the.S. List of, cons of Biodiesel.

Biomass is providing a surprisingly large amount of the worlds energy 10 of total global primary energy consumption (Energy Future Coalition, 2007). Of course, soy is now much more likely to be grown as an industrial commodity than as an ingredient for tofu! And more water resources will be used. It does not produce any hazardous emissions. Algae biodiesel production uses more water than other biofuel sources. Conclusion To conclusion, biofuels have advantages and disadvantages, for the advantages, biofuels is safe because it has high flesh point, enhance national energy security and help countries saving money from import oil. It contributes to the ease of movement of an engine, also known as lubricity. For Soil erosion, when cellulosic ethanol is produced from feedstock like switchgrass and saw grass, the nutrients that required to grow the lignocellulose are removed and cannot be processed by microorganisms to replenish the soil nutrients, then the soil is of poorer quality.

Bishop Brady High School : Departments

Also, some of the nutrients in the fertilizer are made from petroleum sources. It is estimated that a biodiesel blend of just 1 can increase fuel lubricity by as much. Any opinions, findings, conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views. In addition to that, it is also renewable. For one, since such fuels are derived from agricultural crops, they are inherently renewableand our own farmers typically produce them domestically, reducing our dependence on unstable foreign sources of oil. Increase the use of biofuels will definitely increase the use of water resources, such as: water will be used for the irrigation of crops used as feedstock for biodiesel production and water is used for boiling and cooling in the. It helps extend the working life of engines. Because of its safety, the number of incidence of severe vehicle fires can be reduced, and its safety making it to be one of the safest of all alternative fuels. Currently, biodiesel is the only biofuel to have successfully completed emissions testing in accordance with the Clean Air Act. Algae biodiesel is net carbon neutral, because the carbon dioxide produced by burning algae biodiesel is the same amount of carbon dioxide that the algae took up to grow and produce the oil. Many manufacturers have included biodiesel in their warranties, however there is still a chance problems will exist. Research shows that it is even ten times less toxic than table salt.
