Energy independence sounds like such a great idea. If only we could be free ... of what, exactly? The single biggest energy exporter to the U.S. is Canada. And even the petrostates we don't like have to sell us oil at whatever price the market sets. We buy lots from Hugo Chávez in Venezuela. He denounces us, we denounce him, but we happily do business together. After all, what else is he going to do with his oil, drink it?
