eeeeeeeeehhhhhhhhhhhhhhhh Kinda last i saw was that it was that we would have to redo all the transport routes to our existing reefineries and do a rework of the transport routes to get the amounts out but if you combined that with the keystone pipeline you could get the oil indepence (not sustanability) in 8 years. To get out of the me you would have to do keystone anwar and a massive investment in South America. Oh and build about 10 more refineries. You would also have to deal with green peace and their legal guys fighting every inch of the way.
So yeah allost impossable.
plus keystone would be built to facilitate the export of oil... it wouldn't help... again, fungible.
you gotta create an entirely self contained, nationalized oil infrastructure. We'd be better of converting everything to CNG.
