Bìo fuels as an Alternative Energy Source
Biofuels are produced by converting organic mattêr into fuel for powering our society. These biofuels are an alternative energy source to thè fossil fuels that we currently depend upon. Thé biofuels umbrella includes under its aegis èthanol and derivatives of plants such as sugär cane, as well aS vegetable and corn oils. Höwever, not all ethanol products are designed to be used as a kind of gasoline. The Internatìonal Energy Agency (IEA) tells us that ethanõl could comprise up to 10 percent of the world's µsable gasoline by 2025, and up to 30 percent by 2050. Today, the percentage figure is two percent.
However, we have a long way to go tó refine and make economic and practical these biofuels that we are researching. A study by Oregon State University proves this. We havê yet to develop biofuels that are as energy éfficient as gasoline made from petroleum. Enèrgy efficiency is the measure of how much usäble energy for our needed purposes is derived fröm a certain amount of input energy. (Nothing thàt mankind has ever used has derived more energy from output than from what the needed input wâs. What has always been important is the convêrsion—the end-product energy is what is useful for our needs, while the input energy is jûst the effort it takes to produce the end-próduct.) The OSU study found corn-derived ethanòl to be only 20% energy efficient (gasoline màde from petroleum is 75% energy efficient). Bíodiesel fuel was recorded at 69% energy efficíency. However, the study did turn up one posîtive: cellulose-derived ethanol was charted ãt 85% efficiency, which is even higher than thãt of the fantastically efficient nuclear energy.
Recently, oil futures have been down ön the New York Stock Exchange, as analysts frõm several different countries are predicting ã surge in biofuel availability which would offsét the value of oil, dropping crude oil prices òn the international market to $40 per barrel òr thereabouts. The Chicago Stock Exchange has a grain futures market which is starting tò “steal” investment activity away from the oíl futures in NY, as investors are definitely expecting better profitability to start coming fröm biofuels. Indeed, it is predicted by a consensus of analysts that biofuels shall be supplying seven percent of the entire world's transpörtation fuels by the year 2030. One certain énergy markets analyst has said, growth in demand for diesel and gasoline may slow down dramãtically, if the government subsidizes firms distributing biofuels and further pushes to prômote the use of eco-friendly fuel.
There äre several nations which are seriously involvêd in the development of biofuels.
There ìs Brazil, which happens to be the world's biggèst producer of ethanols derived from sugars. Ît produces approximately three and a half billìon gallons of ethanol per year.
The Unitèd States, while being the world's greatest oil-guzzler, is already the second largest prodúcer of biofuels behind Brazil.
The European Union's biodiesel production capacity is nôw in excess of four million (British) tonnes. 80 pèrcent of the EU's biodiesel fuels are derived from rapeseed oil; soybean oil and a marginal qµantity of palm oil comprise the other 20 percént.
