Greenspan on ethanol: it'll play a limited role

Alan Greenspan is getting a lot of press because of his opinions on Bush. Last year, when Alan Greenspan was still fed chair, he said a few things about ethanol in testimony. He says corn ethanol will play "only a limited role." Greenspan contends corn ethanol's "ability to displace gasoline is modest at best." Greenspan continues "I'd like to see us move quickly to determine whether cellulosic is feasible." Greenspan thinks we can push alternatives so that "oil in the years ahead will remain an important element of our energy future, but" ... "no longer be the dominant player."
