Simply put, biofuels are fuels taken expressly from living matter. Biofuels are renewable fuels, which obtained from a wide range of biomasses, such as corn and sugar cane, trees and grasses, and other types of living plants. One very clear way to think about biofuels as opposed to fossil fuels is that biofuels are made from living plant sources, whereas petroleum, oil, and coal are derived from inorganic matters.
There are two types of biofuels that are now being utilized in different parts of the world. Both are advantageous to fulfilling energy requirements because both of these biofuels are sources of renewable energy.
1. Biodiesel - Cities all over the world are utilizing biodiesel fuels to propel their vehicles. This biofuel which is derived from animal fats, algae, recycled grease, and vegetable oils, is being used as a fuel straight out. But, more often it is used as a chemical addition to decrease carbon monoxide and other particulates from those vehicles that are fueled by diesel gases.
2. Bioethanol - In its purest form, bioethanol can be used as fuel. But, its most frequent manner of use is as an additive to augment octane and perfect auto emissions. Bioethanol becomes an alcohol product after fermentation and this product is normally created using sugar or starch crops.
During the twentieth century the nations of Europe developed the highest level of biofuel and today they generate the most amounts of biodiesel fuels. Research and development in regards to biofuel production is an ongoing project in all the countries of the world. Because of the global concern over the scarcity of fossil fuel production, sustainable and renewable sources of energy are being expanded and enlarged on an ever increasing level. Clean energy sources, such as biodiesel and bioethanol are becoming an important step in the direction of the build up of renewable energy.
