Dear Everyone, as you know the price of the Oil is more and more increasing, while the oil supply is decreasing. Moreover Oil is causing wars, terror, oil spills and a lot of greenhouse gases. By upgrading your car to flex fuel, you will continue to be able to use oil. However you will also have the opportunity to use E85, that means more freedom of choice. The conversion cost is about 200-250 USD. By choosing ethanol, you choose local fuel production, which means labour for farmers, labour for enginneers and workers in the ethanol plant, labour for transportation. Moreover you also help for indirect labour. Since the money stays in your country, this money will turn and produce indirect labour. Since the farmer will gain your additional fuel money, he will buy other things (labour is again needed for their production), which in case of oil the oil-Sheikhs or their people would do. That ethanol production increases the food prices is also not totally right, first there is a by-product called "distillers dried grains with solubles", which is used as feed for livestock, that is also nothing else than food. Moreover, by using ethanol, you put pressure on oil prices, which has also an important effect on food prices. You also give your money for more research (again labour), which will yield in higher efficiency of production and alternative production methods like cellulosic ethanol, which will change the whole equation. Again in case of oil this money would be spent for oil rigs, oil- infrastructure, but also for weapons to defend the oil. By using ethanol, you produce less CO2, since it is produced by corn, which actually consumed the CO2 in the air for its growing. The more people use ethanol, the higher the efficiencies will come for production (similar to solar cells). The prices will go further down, and much less CO2 will be produced during production in the plant. Do you know that the production efficiencies already improved 30% ?* Another reason for using ethanol is that oil prices will come up again, when the barrel price of 150 USD is back you will be very happy to have your vehicle converted. The conversion also increases the value of your vehicle.
