This means it will be a big inconvenience to get a refill. New studies address the use of waste water and recycling of used algae water for a more efficient production of algae biodiesel. Another major hurdle for widespread adoption of biofuels is the challenge of growing enough crops to meet demand, something skeptics say might well require converting just about all of the worlds remaining forests and open spaces over to agricultural land. It is environmentally friendly. The numbers might look quite different, though, for biofuel derived from agriculture waste products which would otherwise end up in a landfill. Studies are underway to develop efficient recycling methods that will return phosphorus and nitrogen from used or left over algae biomass back into the growth media bio diesel pros and cons essays for new algae growth.

And unlike other forms of renewable energy (like hydrogen, solar or wind biofuels are easy for people and businesses to transition to without special apparatus or a change in vehicle or home heating infrastructureyou can just bio diesel pros and cons essays fill your. It can affect the food supply. Impact on water resources.
Nowadays, as the problem of greenhouse gases emissions is getting more serious, Carbon-negative biofuels represent the first potentially huge assault on the problem, in ways that are already technically feasible and practicable (Mathews, 2008). As a result, it prevents clogs and prolongs the working life of an engine. Should we advocate harder for the government to invest more in this biofuel?

If it would be used during cold climates, the tanks would require heating. And as public awareness grows, biodiesel can be a solution that will win more positive support. Biodiesel is known to gel in colder temperatures. All this concern over oil has brought out more interest in alternative fuels, including biodiesel. Alternative fuel sources will be a necessity in the near future. He found similarly troubling numbers in the process used to make biodiesel from soybeans. This means it is less likely to accidentally combust because it burns at a higher temperature, thus, it makes storage and transportation easier and safer.
On the other hand, biofuels industry can also create new job opportunities in rural areas and a major new source of income for farmers can also be provided. There is just no energy benefit to using plant biomass for liquid fuel, Pimentel says. Growing energy crops is more likely to attract the kind of foreign investment that can modernize their agricultural practices as well as increase their food production (Energy Future Coalition, 2007). Biodiesel is one of the major biofuels, fuels made from biological ingredients rather than fossil fuels. Get help with your essay today from our professional essay writers!

This bio diesel pros and cons essays is not an example of the work produced by our. You can view samples of our professional work here. Another dark cloud looming over biofuels is whether producing them actually requires more energy than they can generate. Biofuels Are Easy to Use, but Not Always Easy to Find. To produce 39 billion liters of algae biodiesel, which would replace about 5 percent of total.S. Large amounts of water are needed to grow algae in open ponds or closed bioreactors. 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. Biodiesel can be used in diesel engines right away with little or no modification required.
