"Energy independence" is little more than political rhetoric, and pretty silly rhetoric at that.
Petroleum is the cheapest energy available to the world today. It would be cheaper still if not for the efforts of OPEC to limit production.
I can imagine the dear reader's response, that today's oil prices do not include the cost of empire or long term climate impacts. No, oil prices do not include those costs and there is little political will to make prices include them (e.g., a carbon tax).
Foreign oil is cheap and domestic U.S. oil is expensive. The only way to make America energy self-sufficient is to prohibit imports of cheaper foreign oil. Not only would that be crazy, but it would make American exports even more uncompetitive in world markets than they are today. It would also make the energy costs of our competitors cheaper, improving their competitiveness as a consequence. Same thing with a unilateral American carbon tax.
By "draining America first" (i.e., energy independence), we burden our economy in the short term and make ourselves even more dependent on foreign oil in the long term, once our reserves have been exhausted. That just seems stupid to me.
