Every president since Richard Nixon has chased the dream of energy independence, promising to break the U.S. reliance on foreign oil. Today the U.S. is more energy-independent than it’s been in 20 years. But don’t give President Obama too much credit. He came into office promising to jump-start renewable energy and directed billions in subsidies toward the green economy. Meanwhile, a separate energy revolution took hold in the oil and gas fields. New drilling techniques unlocked vast reserves unreachable just a few years ago. Oil and natural gas production in the U.S. is increasing at its fastest rate in 50 years, while imports from OPEC have been cut by a quarter in the last four years.
