TOKYO (AP) — U.S. officials are touting bioethanol in Japan, which trails other nations on using the green fuel made from corn and other crops. The U.S. is a top grower of corn, and an embassy official said the U.S. would be “a reliable supplier” of bioethanol. “American ethanol is a powerful tool for Japan to address climate change, support consumers facing high prices and strengthen energy security,” Aaron Forsberg, minister for economic affairs at the U.S. Embassy, said at a conference center in Tokyo.
