I really have a problem with ethanol. A lot of people don't realize that fossil fuels are burnt in the production of ethanol. They also don't realize that ethanol is far less efficient that petroleum products (like thesceptic said). True it may reduce the dependence on oil, yet at what cost? At just about any gas station I fill up at, I recieve E85 which makes me think about the profit margins in gasoline sales. I understand gas is expensive because crude oil has skyrocketed but I'm only getting 15% real gasoline. Another problem is that the world is going through a food crisis that is overlooked becaused the industrialized West has other issues to worry about ie rising gas prices. Its incredible how the price of rice has more than doubled in one year (has increased something like 250% over the past 6 years but don't quote me on that one) yet little is done about that. It is not only rice that has increased so exponential, but also wheat and corn. Take what you want from it, but corn farmers recieve subsudies to grow corn that will be used for ethanol production...
