"By some estimates, there will be an average of two percent annual growth in global oil demand over the years ahead, along with, conservatively, a three percent natural decline in production from existing reserves"..."That means by 2010 we will need on the order of an additional fifty million barrels a day. This is equivalent to more than six Saudi Arabias of today's size." -- Dick Cheney (as CEO of the world's largest oil services company, Halliburton) in a 1999 speech to the International Petroleum Institute in London.
