Thanks to Eric Garza (UVM RSENR) for putting me onto this dense and fascinating report that summarizes the energy use in our food system. I was surprised to learn the per capita energy use in our food system increased significantly from 1997 to 2002.
From the report;
“Energy is an important input in growing, processing, packaging, distributing, storing, preparing, serving, and disposing of food. Analysis using the two most recent U.S. benchmark input-output accounts and a national energy data system shows that in the United States, use of energy along the food chain for food purchases by or for U.S. households increased between 1997 and 2002 at more than six times the rate of increase in total domestic energy use.
…
The use of more energy-intensive technologies throughout the U.S. food system accounted for half of this increase, with the remainder attributed to population growth and higher real (inflation-adjusted) per capita food expenditures.”
