For now, the increase in ethanol production means that Minnesota will be able to reduce its stockpiles of corn. The future, though, is the big unknown.
A vice president of Monsanto quoted in the article says he expects ethanol to require 25 percent of the U.S. corn supply once all the production facilities currently in production are completed (so, in about 18 months or so). Currently, ethanol uses about 15 percent. Citigroup pegs the number even higher, at 31 percent.
