This isn't about oil money, rather corn money. Ethanol factories produce more greenhouse gasses than any refineries. BUT, our good ole' boys in the beltway have corn payoffs to the farms to produce limits, which go to the refineries, via subsidies.
Meanwhile, back in the City, the Beltway boys have their free money from the Federal Reserve(in the form of QE infinity) placed in the stock market under the corn commodities. Watching it go up and laughing at us for being stupid, thinking it's a "save the planet" issue.
