In the recent years, more and more people use biofuels as to save money and rescue the world from global warming. Therefore, it is difficult to form an idea of the benefits or drawbacks of biofuels. A fuel which derived from organic matter, usually obtained from plants directly or indirectly from agricultural, commercial, domestic, and industrial wastes are known as biofuel. (Business Dictionary, 2018) To discuss the benefits and drawbacks of biofuels, it can separate to different aspects: social, economy and environment.
The United States of America is a country which produces most biofuel in the world. (Myers, 2015) One of the most well-known biofuel company – Arizona Biodiesel, its CEO, Dan Rees, believes that biofuel should benefit the local economy and benefit the local environment. (Hardaway, 2009) In the aspect of social and economic, creating new career opportunities in the rural area is the benefit of biofuel. The biofuel’s company could employ different workers to increase the revenue, consequently, decrease the unemployment rate. Besides, demanding of suitable bio crops increased, hence, biofuels companies employ more workers as to provide economic stimulation in the agriculture industry. One more point to point out, compared to the fossil fuels, biofuels are easily renewed. The more biofuels we have, the more revenue earned and the more job opportunities we have.
Divided to the social aspect, biofuels are convenience of the world. To compare with the renewable energy such as solar energy and wind energy, it does not require to change or to switch to use. (Morriss, 2011) Regarding to the transport vehicle, the using of biofuels (bio-diesel and bio-petrol) do not need to change in the engines of vehicles as well.
On the other hand of the economic aspect, according to the Clean Cities Alternative Fuel Price Report. Biofuels are far more expensive than the traditional fuels as chemists improve biofuels to be an efficient energy output. Therefore, a high cost is required. (2017) Even though companies can employ workers for investments and harvest, yet as demand for food crops such as corn grows for biofuel production, it raises prices for necessary staple food crops. Therefore, the core problem of developing biofuels cannot be solved and it prevents the use of biofuel become popular.
From the aspect of the environment, as it can reduce the pollution of the world, biofuel is invented to save the planet. Data showed by the United States Environmental Protection Agency (2017), the air quality has continued improving since the implementation of the Clean Air Act – using biofuels and other method to reduce air pollution. When we burn the biofuels, they will produce carbon as well, whereas they generate lower carbon emissions and fewer toxins. It is a safer alternative to improve the atmospheric quality and decrease of air pollution.
Nevertheless, biofuels are required much more quantities to spend in order to produce the same level of energy since it has a lower energy output than the traditional fuels which we use nowadays. Undoubtedly, they are not worth to convert them to ethanol rather than electricity. We know that biofuels are cleaner to burn, still there is strong significance that producing fuel has heavy carbon emissions. For example, cultivate the crops and plants to produce fuels by using machine necessarily and besides, cutting trees in forests to grow bio crops for biofuels adds to carbon emissions as well. This is called deforestation, is therefore contributing to an un-sustainable global warming atmospheric and a reduction of biodiversity.
To conclude the three aspects which raised: social, economy and environment, biofuels have its benefit and drawbacks. It can benefit to our planet, yet it can harm our biodiversity. From the advantages and disadvantages which has discussed above, we learnt that biofuel does help to solve the problem of global warming. However, it is too early to say it is significantly benefit to our world nowadays and in the future as well since there are still different problems need to be tackled, drawbacks are still exist.
