Ethanol use in the U.S. rose sharply in recent years due to public policy and a spike in petroleum prices, and remains high. Public support for ethanol includes mandated minimum levels of use nationwide. However, rather little is known about consumer demand for ethanol and much less about demand by type of blend and ethanol source. We used trial survey data and conjoint analysis to overcome the lack of historical data on consumers’ preferences for ethanol blend fuels. Preliminary findings based on responses from vehicle drivers in Missouri suggest that price is the primary factor behind fuel preferences. The disclosure of ethanol originated from woody feedstocks had a significant effect on preferences ceteris paribus. Ethanol blends of 20 percent had a negatively non-significant statistical effect compared to no-ethanol fuels or those with a 10 percent content. These findings will be tested using different models expanded to a nationwide pool of motor vehicle drivers.
