Annual biofuel production by state, covering ethanol and biodiesel. The US is the world's largest ethanol producer, with production concentrated in Corn Belt states. This data reflects the physical volume of biofuel produced, not energy content.
Biofuel production data are sourced from the EIA State Energy Data System (SEDS), which collects state-level energy production statistics. Values represent the physical quantity of biofuel produced and are expressed in million barrels.
