The ethanol is a fuel that does not derive from petroleum but from vegetables like the wheat, the beet or the cane of sugar. She is one of the alternatives more spread to the fossil fuel to world-wide level, impelled mainly by Brazil and the United States. Like all recent technological advance, its expansion in the market can be slow and expensive, but even so, can get to mean the construction of a model of growth and development from the production of clean energy sources and, simultaneously cheaper than its present alternative. The stops and crescents prices of petroleum stimulate the search of new solutions able to replace it. The market becomes more and more competitive and

the more profitable businesses are day after day. It is so the government of Brazil tries to be associated with the sector deprived with a joint investment of US$ 9.6 million for the international diffusion of the national ethanol, obtained from the sugar cane. Of the world-wide production of 50,000 million annual liters of ethanol, only 10% move from a country to the other. Of that international market, Brazil it controls 70% and it aims to extend it through two clients of enormous potential as they are it Asia and the European Union, that they have adopted political of obligatory use of the ethanol. In Brazil, for example, the gasoline that is distributed between the consumers finds mixed with until a 25% of ethanol, by means of the adoption of the system flex in the automobiles of the internal market, that allows the joint fossil gasoline combustion with ethanol. This way, the costs are lowered the price of and a significant contribution to the environment is realised. Even so, the thickness of the ethanol production has as main application its industrial use and not like fuel at domestic level, in a relation that little by little is beginning to revert itself.
