U.S. energy policy has been shaped by one critical event that happened 40 years ago this week: the OPEC oil embargo of 1973. Since then, the United States has embarked on an ambitious goal of drilling for our own oil and gas, as well as diversifying our energy portfolio. In this segment, Joel discusses why the shift away from OPEC domination could be a major opportunity for companies like Schlumberger (NYSE:SLB) and Kinder Morgan (NYSE:KMI) as well as whether OPEC is still the force it once was.
