This study aimed to evaluate and conserve energy consumption for both input and output per unit area in Shahrekord, Iran, focusing on sustainable potato production. A questionnaire was developed and administered at various stages of potato production, covering planting, growing, and harvesting operations across three different irrigation systems: Surface, Sprinkler, and Tape. Equivalence equations were used to convert the energy consumption metrics per unit area. The average energy consumption and production per unit area were 137089 and 149085 MJ ha ¹, respectively. In the surface irrigation system, the values were 95103 and 119118; in the sprinkler irrigation system, they were 141302 and 149273; and in tape irrigation systems, they were 91428 and 156600 MJ ha ¹. The mean energy use efficiency index was 1.14 overall, with values of 1.18, 1.06, and 1.71 for surface, sprinkler, and tape irrigation systems, respectively. The average water use efficiency was 5.1 kg per cubic meter, with values of 3.74, 6.25, and 10.6 kg m ³ in the respective irrigation systems. Only 0.406, 0.338, and 0.585 kg of potato crop were produced for each megajoule of nonrenewable energy utilized in the mentioned irrigation systems. These results indicate that energy and water use efficiency were high in the tape irrigation system.
