I have recently been using youtube to get my fix of decent BBC Comedy and stubbled upon Rob Newman's (AKA one half of Newman and Baddiel) excellent one man show - The History of Oil.
He comes to a very interesting conclusion that the war in Iraq had little to do with WMD's or even Energy Security (although this is obviously a beneficial side effect). In fact he concludes that due to a number of OPEC states (axis of evil #1, #2 & #3) deciding to move the sale of oil from the universal USD to EURO's that the US was actually protecting its currency.
In fact it becomes increasingly obvious when you look at how much the war in Iraq will end up costing. $3t dollars is a number that has recently been reported. This is actually enough money to pay for the development costs of enough wind farms to totally negate the United States requirement of fossil fuels for generation of electricity at current consumption levels. It would also reduce the United States GHG emissions by nearly 40%.
