Sweet sorghum (Sorghum bicolor) is primarily grown in Kentucky for its syrup. However, this crop may someday have another use in the Commonwealth—as a bioenergy crop. From 2007 to 2009, University of Kentucky researchers examined the feasibility of ethanol production from sweet sorghum. They concluded that "overall sweet sorghum would appear to be a very feasible crop for ethanol production in Kentucky." Additional states, along with several other countries, have also been actively conducting research on sweet sorghum for biofuel and with promising results.
