I suspect your figures on amount of recoverable oil in other countries is based on “old” technology. It is likely other areas of the world will find additional oil reserves, using the new technology, similar to those in the USA. There is nothing particularly notable about North American geology relative to other parts of the world.
What this means, of course, is that the world probably has a significant multiple of the recoverable oil that we thought we did a few years ago. Which blows a pretty big hole in the “peak oil” hypothesis.
Absolutely!
All of which goes to the point of this thread which is that we can and should be developing ALL of our energy resources in this country and would be absent POLITICAL considerations.
