If USA is not dependant on Oil , also the rest of the world If alternative fuel is the future . All of the middle east and other muslim countries will be back to the old ages. all these guys make money from Oil consuming countries. Will be back to riding the camel in the desert
Alternative fuel is the future of course, but the oil will last longer than expected until now. New ways of collecting the oil can extend the oil age maybe 50 years. But the middle east will be rich forever, they build their new income now on the oil money and will not be depending on the oil to be rich also in the future.
