Time magazine has a brief article on how hydraulic fracturing is changing geopolitics: "America’s improved bargaining position vis-à-vis Iran is just one example of how the 21st century geopolitical order has been upended by the energy revolution underway in the U.S., according to Elizabeth Rosenberg, who authored the report. The downward pressure on oil prices created by plentiful crude in North America gives the U.S. leverage it didn’t previously have in dealings with all major petroleum exporting states, including some that have been particularly irksome to the U.S. of late, like Venezuela and Russia."
Just something to remember.
