The Brazilian economy is doing well inspite of the Subsidies given to Ethanol industry. Let me clear a few things up though, Brazils case in the world is unique because it can produce Ethanol more cheaply than any other nation in the world from Sugarcane. Therefore if Ethanol takes off globally it would crush the worldwide competition and instead of U.S. being dependant on Middle East Oil, it would become Dependant on Brazilian alchohol.
I could prove it, but I am lazy and I should be doing my assignments. Im not saying it has more emissions, only that it doesnt have much lower emissions than normal petrol does and when you factor in the forests cut down for growing sugarcane, it comes out worse on the Environmental score card.

Sigatoka, i am really disapointed by your limited intelligence. Here i thought we were engaging in an educated discussion. Ethanol is bio-degradable.......................:lips:

[FONT=Times New Roman, Times, serif]Ethanol[/FONT][FONT=Times New Roman, Times, serif] is a popular and environmentally friendly fuel which when used as a transportation product reduces the need for foreign oil and fossil fuel. Over two million miles have already been driven on an ethanol blend of 10% ethanol and 90% gasoline (E10). E85 is the term used for motor fuel blends up to 85% ethanol and 15% gasoline. E85 is considered an alternative fuel under federal and state laws.

[FONT=Times New Roman, Times, serif]Ford, GM, Chrysler, Mazda, Isuzu and Mercedes offer approximately 20 different models of cars and trucks capable of using any mix of gas and ethanol -up to 85% ethanol- without modification. These vehicles are available from most new car dealers for no additional cost. Nearly three million of these Dual Fuel or Flexible Fuel Vehicles (FFVs) are presently on the road. Approximately 240 US gas stations now offer E85 and more are added each month. For national locations see www.e85fuel.com[/FONT][/FONT]

E85 has the highest oxygen content of any fuel currently available. The Argonne National lab has concluded use of corn-derived ethanol can reduce lifecycle greenhouse gas emissions by 14-19 percent when compared to gasoline. E85 is a higher performance fuel with an octane rating of 105-110. E85 users will notice a mileage and range reduction of 10%-30% because a gallon of ethanol contains only 70% as much energy as a gallon of gasoline. However, since a vehicle will perform better on ethanol than on gasoline, vehicles can be ethanol-optimized (capable of running only on ethanol) to achieve superior gas mileage as compared with gasoline.[/FONT]

Ethanol is nontoxic, renewable and biodegradable, and can be made from almost any agricultural feedstock from which starch is derived, such as sugarcane, sorghum, wheat, cheese byproducts and wood waste, municipal solid waste, animal manure and sewage sludge. New Mexico has one ethanol production facility in Portales that produces 15 million gallons of ethanol per year from Milo (sorghum). According to the American Bioenergy Association, biomass used to produce ethanol could reduce our oil imports upwards of 50%!
Although the vast majority of ethanol is currently produced from corn or corn byproducts, ethanol can be made quite economically from cellulosic sources as well. Thus ethanol could be produced from forest thinnings that must be removed from the forests of the Southwest in order to prevent catastrophic fires. [/FONT]

When combusted, ethanol is carbon neutral when made except for the use of fossil fuels used during its production. That is, the carbon released when ethanol is combusted is recaptured when new plants are grown to reproduce more ethanol. Combustion of fossil fuels, on the other hand, circumvents the natural carbon cycle by releasing carbon that has been locked away by nature without providing a way to reabsorb the newly released carbon. Thus, the use of carbon-neutral ethanol helps slow down global warming.[/FONT]
