IS THIS REALLY GOOD NEWS? U.S. To Beat Brazil As World’s Leading Ethanol Exporter. Plus, a regulatory/subsidy fail: “Since the federal renewable fuel mandate classifies sugarcane ethanol as an advanced biofuel, but corn-based ethanol as only a biofuel, it’s quite likely the United States will continue to export corn-based ethanol to Brazil while at the same time importing mass quantities of the sugarcane-based biofuel from Brazil.” Well, it’s a “fail” except for the people making money off it.
