An Introduction to Biofuel

oil prices have always been a concern. Recent developments, combined with increased environmental awareness, we have shown the need for the creation of alternative energy. Many options have been proposed. Nuclear power is possible, but come with obvious safety problems. Solar and wind look like viable options, but do not seem to be getting lots of support. Another option is biofuels, which involves the use of energy from organic materials to replace the role of fossil fuels. Ethanol is perhaps the most widely used of these, especially in Brazil and the United States, and is used most commonly as a mixture with regular fuel. Another type of biofuel is biodiesel, which is made from vegetable oils or animal oils or. It is actually possible with current technology to take the fat from the grill at McDonalds and recycle it into usable fuel! As with ethanol, which can be used exclusively on their own but is only a supplement to be added to another fuel. It is currently the most common biofuel in Europe. The process of converting animal and vegetable oils into usable fuel is called transesterification. 1. 8% of transport fuel from biofuels in the world was in 2008. This figure seems small, but investment in these technologies is growing, and inevitably create new technological advances and increasing popularity. Biofuels come in many different ways, and are usually classified in the first generation, second and third. First-generation fuels are made from food crops such as sugar, starch and animal fat or oil. The grains can be made into bioethanol and sunflower seeds in vegetable oil and then biodiesel. These are the first generation biofuels more common: biodiesel, bioalcohols, vegetable oil, bioethers, solid biofuels, syngas and biogas. Of the non-food crops such as waste, wheat stalks and corn yields the second-generation biofuels. Since first-generation biofuels are made from food sources, hunting is to create a second generation technology that can prevent food shortages that may occur. Include biohydrogen biomethanol, mixed alcohols and wood diesel. Third-generation biofuels are the most complex, and are usually from algae, which produces a large amount of energy. While the benefits of third-generation fuels would be great, because it is virtually impossible to cause damage to the environment, technology has so far not been sufficiently developed to allow these biofuels that are commercially produced. It has been repeated, that 15,000 square miles of algae could supply all the fuel oil embargo imposed by the United States. These new technological developments show how exciting the field of biofuels is, and can provide great benefits to the environment. The existing environmental problems and massive fuel price arrangements might be forever fuel the further development of second and third. Who knows what we will feed fifty years from now?
