   HOUSTON, TX (DTN) -- E15 sales in Iowa surged 60% in a single year, topping 
410 million gallons in 2025, according to the Iowa Department of Revenue's 
newly released Retailers Motor Fuel Gallons Annual Report.

   At the end of 2025, nearly half of the state's fuel stations offered E15 
(gasoline blended with 15% ethanol), with the blend accounting for 27% of all 
gasoline sold, according to a statement released Tuesday (3/31).

    "With Iowa drivers saving an average of 15 cents per gallon by choosing 
E15, the cost savings equaled an estimated $61.5 million. E15 is well on its 
way to becoming the new normal fuel in Iowa," said the state's Renewable Fuels 
Association executive director Monte Shaw.

   However, biodiesel sales fell from nearly 82 million gallons in 2024 to just 
under 51 million gallons in 2024.  Shaw said the decline was driven by federal 
policy instability, citing low Renewable Fuel Standard blend levels and unclear 
tax credit guidance.

   Last week, the Environmental Protection Agency issued a waiver allowing 
nationwide summer sales of E15 gasoline.
