摘要: Today’s agriculture provides an ever increasing population with sufficient quantities of food. During food production, processing, handling and transportation, amount energy is invested into the various products. An analysis a typical American diet policy makers, farmers public necessary information to evaluate make informed decisions as how improve efficient use energy. At same time, consumer may become conscious be able dietary choices based on balance. This paper studies sequestered in defined Food Agriculture Organization United Nations, Statistics Division (FAOSTAT). The incorporated this 3628 kcal (15.18 MJ) per person day produce, transport, handle process foods calculated found have approximately 39.92 GJ (9.54 Gcal) year. It shown that line States Department (USDA) recommendation around 2100 (8.79 will result reduction inputs by 42% annual basis. for whole America (USA), corresponds 879 million barrels oil equivalent (boe) savings. Energy efficiency categories studied varies from 3.4% 56.5% average 21.7%. can further improved some through either or yield increase.
