Here’s an article on ADM CEO Pat Woertz, who will be one of the many speakers at this week’s Renewable Energy Conference in St. Louis.

The story talks about Woertz’s former life as a Chevron executive and her opposition to ethanol at the time, which she said was “tied to federal clean-air standards for vehicle emissions and the debate over how to meet them.” Now she says, “Things have evolved,” she said, and the oil industry and ethanol producers “have come to work much more closely on the fuel supplies for this country.”
