The Environmental Protection Agency (EPA) has authorized the sale of cheaper, higher-ethanol E15 gasoline across the United States this summer. This decision, applauded by agriculture leaders and the Trump administration, includes an emergency waiver allowing for nationwide sales. The move aims to cut fuel costs for drivers and address demands for U.S. grown corn, though it has faced environmental concerns. The EPA has also approved year-round sales of E15, providing a potential long-term solution for higher-ethanol fuel availability.
