US air force eyes green fuel

US air force eyes green fuel : "US air force global operations require a huge amount of energy. In fiscal 2006, the service consumed almost 2.6 billion gallons of aviation fuel at a cost of more than $US5.7 billion ($A6.3 billion), according to an air force fact sheet."
Big money, big carbon and greenhouse emissions. Yes, it would be a good idea to look at alternatives and thereby help resolve the pollution and carbon problems facing our planet. It would be of significant help and it would be so much better if that money could be saved and redirected back into he lives of the American people. America has a lot of coal and so it finds it difficult to overlook that and redirect its money and efforts into renewable sources. It needs to be looked at. It is a cost and global warming issue so it is worth thinking about.
