Bio-Fuels Seen As Possible Alternative Sources Of Needed Energy At This Time
Bio-fuels are produced by converting organic substance into fuel for powering our society. These bio-fuels are an alternative energy source to the fossil fuels that we now depend upon. The bio-fuels umbrella contains under its aegis ethanol and derivatives of plants such as sugar cane, as well as vegetable and corn oils. Having said that, not all ethanol products are designed to be put to use as a kind of gasoline. The International Energy Agency (IEA) tells us that ethanol could comprise up to 10 percent of the world's usable gasoline by 2025, and up to 30% by 2050. Nowadays, the percentage figure is two percent.
However, we have a long way to go to refine and make economic and functional these bio-fuels that we are researching. A study by Oregon State University shows this. We have yet to develop bio-fuels that are as energy efficient as gasoline made from petroleum. Energy efficiency is the measure of how much usable energy for our necessary applications is derived from a certain amount of input energy. (Nothing that mankind has ever made use of has derived more energy from output than from what the needed input was. What has always been critical is the conversion - the end-product energy which is what is useful for our needs, while the input energy is just the effort it takes to produce the end-product.) The OSU study identified corn-derived ethanol to be only 20% energy efficient (gasoline produced from petroleum is 75% energy efficient). Bio-diesel fuel was recorded at 69% energy efficiency. However, the study did turn up one positive: cellulose-derived ethanol ended up being charted at 85% efficiency, which is even higher than that of the fantastically efficient nuclear energy.
Recently, oil futures have been down on the New York Stock Exchange, as analysts from numerous different countries are predicting an increase in bio-fuel availability which would offset the value of oil, dropping crude oil prices on the global market to $40 per barrel or thereabouts. The Chicago Stock Exchange has a grain futures market which is beginning to "steal" investment activity away from the oil futures in NY, as investors are definitely expecting better profitability to start coming from bio-fuels. Indeed, it is predicted by a consensus of analysts that bio-fuels will probably be supplying seven percent of the entire world's transport fuels by the year 2030. One certain energy markets analyst has said, growth in demand for diesel and gasoline may slow down dramatically, if the government subsidizes firms distributing bio-fuels and further pushes to promote the use of environmentally-friendly fuel.
There are a variety of nations which are seriously involved in the development of bio-fuels.
There is Brazil, which happens to be the world's biggest producer of ethanol fuel produced from sugars. It produces roughly three and a half billion gallons of ethanol per year.
The United States, while being the world's greatest oil-guzzler, is already the second largest producer of bio-fuels behind Brazil.
The European Union's bio-diesel generation capacity is now in excess of four million (British) tonnes. 80 percent of the EU's bio-diesel fuels are derived from rapeseed oil; soybean oil and a marginal quantity of palm oil comprise the other 20 percent.
There are new health related solutions which have been made, from zero point energy. To learn more about these try researching words like "amega", "amwand" or "zero point wand comparisons" in your preferred Internet search engine.
