Previous efforts in rural energy modelling have been reviewed and critically examined. A system-dynamics model of an integrated energy system for farming in Bangladesh has been developed based on Hug＇s revised model. The model considers energy use in various forms, including food production and consumption. The physical quality of life is also discussed. The model incorporates existing feedback loops, non-linearity, and time-lag characteristics inherent in real world systems. The model has been used to simulate different energetic variables for farming systems in Bangladesh. Implications of policy changes are discussed.
