2018 values are preliminary.
This chart shows total U.S. corn use from 1986 to 2018. The overall trend has been one of increasing production. The amount of corn used for ethanol production increased substantially between 2001 and 2010, as nearly all gasoline was transitioned to 10% ethanol. The increased ethanol seems to have come from the increase in overall corn production and a small decrease in corn used for animal feed and other residual uses. The amount of corn used for other uses, including human consumption, has stayed fairly consistent from year to year. This long-term trend even held true during the drought of 2012, when production, ethanol usage, and feed usage all decreased substantially but other usage held steady. From 2013, the trend remains consistent with production and usage remaining relatively constant.
