From Wikipedia, the free encyclopedia

Ethanol fuel in Brazil provides a ~22% ethanol blend used nationwide, plus 100% hydrous ethanol for four million cars. The Brazilian ethanol program provided nearly 700,000 jobs in 2003, and cut 1975–2002 oil imports by a cumulative undiscounted total of US$50 billion. Brazil gets more than 30% of its automobile fuels from sugar cane-based ethanol.

The Brazilian government provided three important initial drivers for the ethanol industry: guaranteed purchases by the state-owned oil company Petrobras, low-interest loans for agro-industrial ethanol firms, and fixed gasoline and ethanol prices where hydrous ethanol sold for 59% of the government-set gasoline price at the pump. These pump-primers have made ethanol production competitive yet unsubsidized.

In recent years, the Brazilian untaxed retail price of hydrous ethanol has been lower than that of gasoline per gallon. Approximately US$50 million has recently been allocated for research and projects focused on advancing the obtention of ethanol from sugarcane in São Paulo.
