The energy cost of producing major food crops in Enugu State of Nigeria were determined and evaluated. Energy analysis of producing yam, cassava, maize, coco yam, rice, groundnut, black beans and Bambara nut were carried out based on field operation, fertilizer application and harvesting. Operational energy used in form of direct and indirect energy and energy sources involved in the production process were computed. The major issue of concern is that farmers use more energy to increase output but they do not have enough knowledge on most efficient energy inputs to use. The research study was planned on the basis of investigative survey research approach which involving the use of questionnaire and personal interview with the major produce of the selected crops during the field trips. In carrying out this investigative survey, the author visited thirty-two (32) farmers from each of the nine LGA selected within the stipulated time. The results showed that land preparation operation activities consumed the highest percentage of energy for producing maize, coco yam, rice, groundnut, black beans and Bambara nut (34.76 %, 32.50 %, 38.35 %, 31.18 %, 28.81 % and 28.42 %) except on cassava and yam that recorded highest production energy at harvesting (21.65 %) and planting (76.03 %) respectively. It was gathered also that direct, renewable and non-commercial energy used were higher than indirect, non-renewable and commercial energy used in producing those selected crops in the area.
