CHICAGO — U.S. ethanol output rose more than expected to near-record rates last week, the U.S. Energy Information Administration said Wednesday.Ethanol makers, including top producer Archer Daniels Midland Co., ramped up output as profit margins improved on rising fuel prices and demand ahead of the summer driving season, traders and biofuel industry sources said.The EIA said ethanol production in the week that ended June 3 averaged 1.006 million barrels per day, the second largest rate ever after the 1.008 bpd seen in the week ended Nov.
