Ethanol production efficiency improves
Ethanol production continues to increase in efficiency. The latest numbers from USDA’s 2008 Energy Balance for the Corn-Ethanol Industry report show for every British Thermal Unit (BTU) of energy used to make ethanol, 2.3 BTUs were produced. This is a marked improvement from the last report in 2004 when it took 1.76 units of energy to make 2.3 BTUs of energy. The report goes on to say efficiency will continue to improve as the ethanol process evolves requiring less corn per gallon of ethanol plus increasing corn yields will mean more ethanol per acre.
