Look's like we will be able to start to close down the oil refineries soon.
Only one question that no one ever asks is how much energy does it take to produce and refine these alternate fuels. Some figures I have seen on Ethel Alcohol is that it takes 1.2litres of carbon-based energy to produce one litre of Ethel Alcohol without taking the tax breaks into consideration. If this is true we could deplete 100% of our oil reserves to produce 83% of the same amount of alternate energy. The Greens and "Global Warming" crusaders will find a way to put a good spin on these figures but look what happened to the price of food when the alternate energy producers moved into the food market!!!!!
