Before talking about biofuels, you need to know the basics from where it is created from. Biofuels are produced from biomass, which is derived from living or recently living plant matter such as trees, grasses, agricultural residue, algae, and other biological material. “Biofuel is considered carbon neutral”, which absorbs roughly the same amount of carbon dioxide during growth as when it is burnt (Rutherford, 2009). Biofuels is much cleaner than petrol/diesel because of the considerable impact petrol/diesel has on the environment from the high fuel emissions. Biofuels will help decrease dependence on fossil fuels such as oil, gas, petrol, and coal. This paper will discuss the many crops that biofuels derive from, 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 our air quality, and support rural economies.

Canola and rapeseed oil can generate more energy when burned because of the higher oil content and low saturated fat than most vegetable oils. The oil content of canola is forty percent (Perritano, 2011).
8) Sugarcane
Sugarcane is primarily grown in South America Brazil. Brazil’s climate is best suited for the growth of sugarcane.
