Biofuels are when we use organic matter as fuel by converting it into power for use. By producing biofuels, this is an alternative Fat Burning Furnace as we depend on fossil fuels. The ethanol products include under its aegis, derivatives of plants like sugar cane, and also corn and vegetable oils, all part of the biofuels umbrella. Not all of them are designed for use as gasoline, although the International fat burning furnace Agency (IEA) say that by 2025, 10 % of the world's gasoline could be made up of ethanol products, and by 2030, it could be up to as much as 30%. At the moment, the percentage stands at just 2%.

A lot of research is going into biofuels, and it will be some time before we can refine them to make them more economic and practical enough to use. Oregon State University have done a study to prove this. Biofuels have not yet been developed which are as fat burning furnace efficient as petroleum which makes up our gasoline. To put it simply, fat burning furnace efficiency is how we measure the usable fat burning furnace that is derived from the input fat burning furnace by a certain amount. (Up till now we have not come up with any product where the output fat burning furnace exceeded that of what was input). What is most important is the end product fat burning furnace that has been converted and its usefulness for our society's needs, the effort involved is what we put into the input fat burning furnace so as to produce which is the end-product. A study by the OSU found that ethanol which is corn-derived was only 20% fat burning furnace efficient (compared to gasoline that is 75% fat burning furnace efficient and made from petroleum). Biodiesel fuel had a recorded fat burning furnace efficiency of 69%. Out of the study came one positive thing: higher than nuclear fat burning furnace which is effectively efficient, was cellulose-derived ethanol charted as 85% efficient.

The New York Exchange has marked a change in oil for the future, with analysts from many countries having predicted surges in the availability of biofuels, which would offset oil prices, seeing crude oil drop to prices of about $40 per barrel on the international market. On the Chicago Stock Exchange there is more investment activity in future markets on grain, making a "steal" on the oil futures of New York, with investors expecting much better profitability from biofuels to come. By 2030, a consensus of analysts have predicted that biofuels will account for 7% of transportation for all round the world. Demand for and diesel and gasoline will slowly fall dramatically according to one fat burning furnace market analyst, as government supports the use of the more eco-friendly biofuels and subsidise the manufactures of this fuel.

Many nations support the use of biofuels and its production in developement.

Brazil is the biggest in the production of ethanols that are derived from sugars. Approximately three and a half billion gallons of ethanol is produced in a year.

The greatest oil user is the United States, who already come second behind the largest producer, Brazil, in biofuels.

The European Union now have an excess of four million (British) tonnes in biodiesel production capacity, of which 80% is derived from rapeseed oil. The remaining 20% of the EU's biodiesel fuels is marginally from palm oil and the rest comprised of soybean oil.
