Bio-Fuels Are Seen As Alternate Sources Of Energy Today
Bio-fuels are made by converting organic matter into fuel for powering our society. These bio-fuels are an alternate 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, along with vegetable and corn oils. However, not all ethanol products are developed to be used as a kind of gasoline. The International Energy Agency (IEA) informs 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 improve and make economic and practical these bio-fuels that we are looking into. A study by Oregon State University proves this. We have yet to develop bio-fuels that are as energy efficient as gasoline derived 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 humankind has ever used has derived more energy from output than from what the demanded input was. What has always been important is the conversion - the end-product energy which is what is useful for our needs, while the input energy is basically 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 noted at 69% energy efficiency. However, the study did deliver one positive: cellulose-derived ethanol was charted at 85% efficiency, which is even higher than that of the fantastically efficient nuclear energy.
Of late, 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, reducing crude oil prices on the international market to $40 per barrel or thereabouts. The Chicago Stock Exchange has got a grain futures market which is starting to "steal" investment activity away from the oil futures in NY, as investors are unquestionably expecting better profitability to start coming from bio-fuels. Indeed, it is predicted by a consensus of analysts that bio-fuels shall 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 possibly slow down dramatically, if the government subsidizes firms distributing bio-fuels and further pushes to increase the use of environmentally-friendly fuel.
There are several nations which are seriously involved in the growth of bio-fuels.
There is Brazil, which happens to be the world's biggest producer of ethanol fuel derived from sugars. It produces roughly three and a half billion gallons of ethanol per year.
The States, while being the world's greatest oil-guzzler, is already the second largest manufacturer of bio-fuels behind Brazil.
The European Union's bio-diesel production capacity is now in excess of four million (British) tonnes. 80 percent of the EU's bio-diesel fuels are created from rapeseed oil; soybean oil and a marginal quantity of palm oil comprise the other 20 percent.
There also exists new health related solutions which have been made, from zero point energy. To learn more about these try searching words like "amega", "amwand" or "zero point wand comparisons" in your favorite Internet search engine.
Govt Grants For Alternative Energy Sources - Specifically Where The Scenario Stands
In his State of the Union Address for 2007, United States President George W. Bush called for a 22% increase in federal grants for research and development of alternative energy.
Consultants On Natural Energy Sources - Just What They Are Announcing
The alternative energy consultants tell us that the transition from the petroleum-driven economy and society will not be a smooth one, on the whole.
Renewable Energy Project In Japan
The production of energy through what is known as micro hydroelectric power plants has been catching on in Japan. Japan has a myriad of rivers and mountain streams, and these are ideally suited places for the putting up of micro hydroelectric power plants.
An Energy Alternative: Free Energy
There has been much debate about what is often called "free" energy-energy that can supposedly, with the right technology, be drawn straight out of the atmosphere, and in very abundant supply.
What Do You Know About Scalar Energy? One More Type Of Wave Occurring Along With The Regular Transverse EM Energy.
James Clerk Maxwell in 1865, Nikola Tesla in 1899, and E. T. Whitaker in 1903 realized that there was another kind of wave occurring along with the regular transverse EM energy, called longitudinal EM energy. This form of wave energy is referred to as scalar energy.
