In mid November this year had posted a production of 22,900 million litres of ethanol on the other hand, is us remember also, that the Brazilian ethanol industry has more than 30 years of history and used as agricultural inputs from sugar cane, uses modern equipment, it has developed its own technology, the cane residues are used to produce energy in the distillation process, by which the price of Brazilian ethanol is very competitive, and achieved a relatively high energy balance (reason energy produced / energy used in the process) which varies between 8.3 and 10.2 depending on the use of best practices. Ethanol production is concentrated in the Centre and regions south of the country, being the State of Sao Paulo the main producer. Almost 90% of the Brazilian production of ethanol in 2004, was concentrated in these two regions and the almost all the rest is produced in the Northeastern Region. Very interesting to take into account the source of cited information, gives it us that: the Brazilian automotive industry developed vehicles that operate with flexibility in the type of fuel, so-called Flex-fuel vehicles, popularly known as flex in Brazil, since the engine works with any proportion of gasoline (E20-E25 blend) and water ethanol (E100). Available on the market since 2003, these vehicles proved a commercial success, and in August 2008 the fleet of trucks flex had already reached 6 million vehicles, including cars and light commercial vehicles, representing 23% of the fleet of light vehicles in Brazil. The success of flex vehicles, in conjunction with the obligatory use at national level of between 20% and 25% of alcohol mixed with conventional gasoline (gasohol E25) for gasoline engine vehicles, allowed ethanol consumption exceeds the consumption of gasoline from April 2008. To consider other fuels used by the fleet, mainly diesel-engined vehicles, the consumption of distilled ethanol from sugarcane in 2006 was 18% consumption total fuel in the road sector El Dr.
