Watch out for falling ethanol prices if Wal-Mart decides to start selling E85. Officials with the world’s largest retailer met recently with ethanol industry representatives to discuss the possibility of offering ethanol at its 383 U.S. gas stations.

According to an Associated Press story, Wal-Mart brought together a group of industry, government and academic experts on alternative fuels in Washington last week to discuss how Wal-Mart could develop a network for supplying gas stations at its stores and Sam’s Clubs with E-85 fuel. One of those at the meeting was National Corn Growers Association Executive Director Rick Tolman, who said a decision by Wal-Mart to offer E-85 would help solve one of the emerging industry’s problems: not enough availability for consumers.
