1. The largest portion of energy in the food system is consumed by household storage and preparation. 2. Food processing and packaging together account for a little over 25% or 3.5 quads of the energy consumed in the food system annually. 3. Purchasing organically grown food would save energy involved with agricultural production as it would reduce the energy that goes into producing chemical fertilizers and pesticides. 4. Consolidation in the food system means that there are fewer food processing operations, which increases energy used in transportation by increasing the distance between food sources and consumers. 5. Purchasing locally grown produce would reduce energy used in transportation. 6. Eating less meat would reduce energy used in agricultural production. 7. Buying frozen convenience food in bulk could increase energy used in household storage and preparation. 8. The U.S. food system is rather inefficient as it consumes almost 8 times as much energy in producing, processing, packaging, and transporting food than it makes available as food energy output.
