Advantages And Disadvantages Of Biofuels

Earth scientists believe that the world has about 40-50 years left of oil still buried in the rocks. While this number seems far away it is fast approaching with already passing the peak production of oil and the ever-growing number of vehicles on the streets. As well as by 2035 the demand for oil is set to increase by 18 percent. Oil will become more expensive and scares over the next few decades. These are some of the reasons to look alternative fuels such as biofuels. More focus and research should be done in making biofuels a more prevalent alternative fuel source to oil. The first benefit is that biofuels are a renewable energy source and be grown domestically. Second, a form of biofuels called biodiesel can reduce vehicle emissions and lower energy efficiency for vehicles and lastly can tackle global warming.

Biofuels are current crops or waste products used as a fuel source in a combustion reaction where energy is produced with carbon dioxide and water. There are different types of biofuels first the most common types include things such as vegetable oil, biodiesel, ethanol, and methanol. Ethanol and methanol are made from sugar, wheat, or corn in a similar process to brewing. While vegetable oils can be made from peanuts or soybeans and can be directly burned as a fuel or turned into biodiesel. More advanced types of biofuels include biohydrogen made from hydrogen gas made from crops mixed with alcohols. Another one is oil produced from algae grown in ponds or
