Abstract
Using input-output tables for 1972 and 1977 we examine direct and indirect energy use in the production of fourteen U.S. agricultural products. We find that between 1972 and 1977 energy use increased in absolute terms but decreased in terms of Btus required per dollar of output. Although this trend is encouraging in terms of the long-run ability of U.S. agriculture to adjust to higher energy prices, the following caveats should be mentioned; (1) a large part of the decrease in primary energy intensity is attributable to one sector, meat animals, (2) there was a substantial increase in electricity intensity in almost all sectors, and (3) there was an increase in the use of energy embodied in fertilizers and agricultural chemicals in the very important food grain and feed sectors.
