This week, retail experts came together at Growth Energy’s Executive Leadership Conference at the Terranea Resort, in Palos Verdes, California, for a panel to discuss the future of ethanol retail expansion for higher blends, like E15. Nathaniel Doddridge of Casey’s General Store, David Masuret of Cumberland Farms, and Mike O’Brien of Growth Energy sat down for a deep dive on the growth of E15 fuel across the nation and how independent fuel retailers like Casey’s and Cumberland Farms have embraced Unleaded 88 fuel.
