The Case For E15: A Cheaper, Cleaner Fuel, Cassidy Skillett Dec 2024

The Case For E15: A Cheaper, Cleaner Fuel, Cassidy Skillett

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In its name, “E” indicates that the fuel contains ethanol and “15” communicates that 15% of the gasoline blend is ethanol. When Nebraskan drivers pull up to the gas station, they can buy cheaper and cleaner E15. In 43 states - drivers are not so lucky. A new bill would end fuel discrimination of E15 at refueling stations nationwide.

This change is long overdue and would allow E15 to be available year-round in all states rather than just during the winter.
