Where US Oil comes from (Infographic)

Did you know that America exports oil? See http://www.huffingtonpost.com/david-sassoon/us-oil-exports-h... -- in 2008 we were shipping out 1.8 million barrels per day. It's all determined by how expensive it is including how far it must be transported.
Things shuffle all around, and a change at one point causes lots of lines in the graph to be pushed and tugged, until a new equilibrium is found. One can't just say that Canadian oil is twice as important to us as Saudi oil.
Eventually we are going to start running out of oil, and this will be a good time for unstable nations to fuck up the economies of the stable ones. (Our fault for not investing in alternative energy systems, but I digress...) With a strategic reserve that we can tap into, though, these unstable countries are kept in check -- charge a fair price, or we don't buy at all.
It is sort of like "mutually assured destruction", but better... (The similarly is that the protection of each does not come from the actual use of the system, but rather from the fact that it exists.)
Anyway it would be Democratic governments as far as you care to extend the timeline.
There's oil in eastern Canada too, btw: http://en.wikipedia.org/wiki/Hibernia_%28oil_field%29
and in the north: http://en.wikipedia.org/wiki/History_of_the_petroleum_indust...
International news avoids the term "billion" because it can refer to 10^9 or 10^12.
In UK English, 10^9 is called a milliard.
Still, thanks for pointing that out.
Seriously though, isn't Canada's oil in shale and I thought that was the most expensive to produce?
