The purpose of this study was to investigate changes in energy consumption and environmental indicators in the production of crops, including sugarcane, wheat, canola and sunflower during the years 2018 to 2022. Relevant information was collected through statistics recorded in planning management of Imam Khomeini Sugarcane Agro-Industrial Company in Khuzestan province. Using these statistics and sources, the production situation of agriculture and industry products was investigated. Based on the obtained results, in sugarcane fields, energy consumption in the years 2018 to 2022 was calculated as 131.05, 142.47, 152.16, 155.45 and 161.71 GJ ha-1 respectively. Also, energy consumption was equal to 30.49, 32.70, 35.10, 36.52, and 38.02 GJ ha-1 in wheat fields in the considered period. On the other hand, for the production of canola in the years 2018 to 2022, it varied and was equal to 19.44, 20.81, 22.68, 23.83 and 24.86 GJ ha-1 respectively. Also, in sunflower fields in the same period of time, it was estimated as 44.19, 82.14, 61.15, 20.16 and 76.16 GJ ha-1 respectively. The results of environmental effects showed that the highest amount of pollution caused by the effect of resources in sugarcane production is in the mentioned years of 12.08, 12.64, 12.91, 12.40 and 12.47 USD2013. Also, in wheat production this index increased from 61.96 to 68.23, in canola production increased from 79.86 to 85.51, and finally, in sunflower production increased from 61.82 to 65.73. Based on the ranking of the by-products, sunflower, wheat and canola are prioritized for cultivation from the first to the third place respectively. Optimal use of electricity inputs, diesel fuel and chemical fertilizers can help reduce energy consumption and environmental pollution. In order to reduce energy consumption in the production of agricultural and industrial products, it is recommended to use renewable energy sources such as electricity produced from solar sources by photovoltaic systems.
