Abstract: The efficiency of energy flow and the economic viability of agricultural systems are foundational pillars of sustainable energy management and development. This study applies the energy pyramid framework to evaluate energy flow efficiency and conduct an economic analysis to explore the viability of grape production systems in Takestan County, Qazvin, Iran. Data were collected from 220 grape-growers during the 2020–2021 period. Results indicated that fertilizers and electricity were the major energy inputs, comprising 36.51% and 20.12% of total energy use, respectively. The energy ratio and energy productivity were estimated at 5.81 and 0.49 kg MJ −1 . Non-renewable and indirect energy sources constituted 58.16% and 63.29% of the total energy, respectively. Sensitivity analysis revealed that human labor had the highest marginal physical productivity due to the labor-intensive practices of grape production systems. To enhance economic viability, it is recommended to match energy usage to specific operational requirements and maximize system efficiency. These strategies increase labor productivity by streamlining processes and reducing inefficiencies, while optimizing energy inputs to ensure their effective utilization in production activities.
