 Stop Wasting Food: Save Energy

A simple and painless way for you to achieve huge energy savings is by not wasting any more food.

They say that the United States could immediately save the energy equivalent of about 350 million barrels of oil a year, if they stop wasting food.


Their study found that it takes the equivalent of about 1.4 billion barrels of oil to produce, package, prepare, preserve and distribute a year's worth of food in the United States.

Michael Webber and Amanda Cuellar note that food contains energy and requires energy to produce, process, and transport.

Estimates indicate that between 8 and 16 percent of energy consumption in the United States went toward food production in 2007.

Despite this large energy investment, the U.S. Department of Agriculture estimates that people in the U.S. waste about 27 percent of their food.

The scientists realized that the waste might represent a largely unrecognized opportunity to conserve energy and help control global warming.

Their analysis of wasted food and the energy needed to ready it for consumption concluded that the U.S. wasted about 2030 trillion BTU of energy in 2007, or the equivalent of about 350 million barrels of oil.

That represents about 2 percent of annual energy consumption in the U.S.

"Consequently, the energy embedded in wasted food represents a substantial target for decreasing energy consumption in the U.S.," the study said.

"The wasted energy calculated here is a conservative estimate both because the food waste data are incomplete and outdated and the energy consumption data for food service and sales are incomplete."

The study has been reported in ACS' semi-monthly journal Environmental Science and Technology.
