P.2 3rd paragraph: "In 1999, Heller and Keoleian (2000) estimated the total energy used in food production (defined here as agricultural production combined with processing and distribution) to be 10.2 × 10^15 BTU/yr [BNID 104631]. Given a total 1999 U.S. energy consumption of 96.8 × 10^15 BTU/yr (Table 1.1 in primary source), energy used for food production accounted for 10.5% of the total energy used. In 2002, the food production system accounted for 17% of all fossil fuel use in the United States (Horrigan et al. 2002)." BTU=British Thermal Unit=1.06 kJ |
