Before talking about biofuels, you need to know the basis from which they are created. Biofuels are produced from biomass, which comes from living or recently lived plant material such as trees, grass, agricultural residues, algae and other biological material. “Biofuel is considered carbon neutral,” as it absorbs approximately the same amount of carbon dioxide during growth as when it is burned (Rutherford, 2009). Biofuels are much cleaner than petrol/diesel due to the significant impact petrol/diesel has on the environment due to high fuel emissions. Biofuels will help reduce dependence on fossil fuels such as oil, gas, petrol and coal. This document will discuss the many crops from which biofuels are derived, the various types of biofuels, and the advantages (Pros) and disadvantages (Cons) of biofuels. These biofuels will reduce our nation's dependence on foreign oil, improve air quality, and support rural economies. Pros and Cons of Biofuels The fundamental principle on which biofuels work is through the process of photosynthesis, which is how plants capture and store solar energy. The energy stored in plants is converted into many types of biofuels through a process called biocatalysis. Biofuels are developed through agricultural crops. There are two factors why agricultural crops are the main reason for the development of biofuels: the plants are easy to grow and they are a key form of renewable resource. There are many crops from which biofuels are specifically grown and produced. Here is a list of the ten major agricultural crops and a description of each. 10) Corn Turning sugar-rich corn into ethanol is like a brewery. First they grind the beans and mix them with warm water. Then they add yes…half the paper…PS engines last longer by eliminating wear and tear (Perritano, 2011).4) Health BenefitsAccording to Reilly, 10,000 people die each year in the United States from the pollution created from petrol engines (Perritano, 2011). Reilly also said gasoline emissions release nitrogen oxide, acetaldehyde and other pollutants into the air that produce smog that causes asthma and respiratory ailments. As stated previously, biofuels reduce emissions and pollution. Biofuels release only as much carbon dioxide from the atmosphere as their plant source absorbs. In conclusion, biofuels are quickly becoming the future fuel source to run vehicles and equipment. Biofuels have many disadvantages, but the advantages significantly outweigh them. No one has a definitive answer on how to solve today's growing oil and fuel crisis, but biofuels hold great promise..
