Until recently, the Brazilian government highlighted the country as a world’s top ethanol exporter. Accordingly, in 2007, the Brazilian government published a study indicating the possibility of Brazil using  ethanol to meet 5% of global gasoline consumption and, with more advanced techniques, such portion could reach 10% in 2025 [1], with a production of 205 billion liters of ethanol in the country.

Four years later, perspective is completely different. The recent scenario of ethanol in Brazil is characterized by difficulties in supplying the fuel, high prices and need to import the product.

In April, prices of hydrous ethanol and anhydrous ethanol in power plants in São Paulo showed the maximum value ever of the past 10 years. On average, the price of hydrous ethanol at gas station reached 40% over the same period in 2010. As the price of anhydrous ethanol mixed with gasoline tripled during the same period, the price of gasoline was also affected, increasing 15%. Continue lendo »

As previous article, models that allow you to choice fuel, gasoline or ethanol, rule cars for sale in Brazil. Flex-fuel vehicles already represent 46% of the Brazilian light vehicle fleet, whose portion should rise continuously.

Thus, most car owners can choose the fuel they use at the time of fueling. Thus, the demand for gasoline and ethanol becomes more volatile. Although other factors influencing consumer choice, such as autonomy and environmental impact, the relative price of fuels is the predominant criterion of choice. Continue lendo »

Brazilian light vehicle fleet: expansion of flex-fuel and CNG

The Brazilian energy matrix is characterized by a significant ethanol and natural gas participation as automotive fuel alternative to oil byproducts. Having knowledge of the evolution and characteristic of the automotive fleet is a key step to estimate the fuel consumption and guide policies related to the replacement of oil byproducts as well as the mitigation of CO2 emissions.

However, since 1986, after cancellation of Single Automotive Tax, the estimates of the national fleet circulating in Brazil, made by various institutions, have very different results. DENATRAN, National Traffic Department, publishes data on the fleet by vehicle type and states from the registration data conducted in Detran (State Department of Transit).
