Do you have a link?
At $100 per barrel ND has 10 trillion barrels equivalent?
Last I heard 10 billion barrels was optomistic.
But the point is one I would have made comparing us to Europe. As in last century, we produce cheap energy and Europe does not. The outcome will be similar.
But that's just one area. There are several areas. Some easier to access than others.
Assuming oil stays at or above $100 per barrel, Bakken alone is conceivably worth $16,700 billion ~
The EU"s only hope is fusion.
Then, there's gas ~ and looking for total valuation is tough ~ that situation is growing so fast we'll be back to using oil for lubrication and plastic feed stocks. (I'll recheck my earlier numbers, may have jumped a digit ~ but $16.7 trillion is a large number ~ difficult to work with on the fly)>
