Beyond Food Miles

A locavore is “a person who endeavors to eat only locally produced food.” What better diet could there be for an energy constrained world? After all, feeding Americans accounts for about 15% of US energy use, and the average food item travels more than 5,000 miles from farm to fork. It seems obvious that eating locally will go a long way to reducing food system energy use. Yet cracking the case of America’s energy-intensive food system demands that we look beyond the obvious.

A local diet can reduce energy use somewhat, but there are even more effective ways to tackle the problem. Single-minded pursuit of local food, without consideration of the bigger picture, can actually make things worse from an energy perspective.

If you realize you’re spending too much money, the first thing to do is figure out where it’s going. Cutting back on pizza won’t make much difference if you’re spending most of your money on beer. Similarly, the first step in reducing food system energy use is to figure out where all the energy is going. That’s what a team of economists working for the United States Department of Agriculture (USDA) did last year, in a report called “Energy Use in the US Food System http://www.ers.usda.gov/publications/err94/“.

The report contains some surprises. Transportation is the smallest piece of the food system energy pie. Even farming isn’t a particularly big contributor. The big energy users turn out to be food processing, packaging, selling, and preparation. Our kitchens command the biggest slice of the pie, using twice as much energy as the farms that grew the food in the first place.

    “Our kitchens command the biggest slice of the pie” – not if you use a solar oven / hot box. You can reduce your time in the kitchen and the energy used to prepare food, by using a solar oven – we live in the perfect country to employ this method of cooking, yet very few of us do. Perhaps we think it is beneath us?
