Agriculture and energy have always been tied by close links although the nature and strength of the relationship keep changing over time (FAO 2008). In modern agricultural production, energy consumption is one of the major factors that establishes security and abundance in food supply chain. This is very true as agriculture became increasingly reliant on chemical fertilizers, the use of pesticides, the introduction of new hybrid varieties, the application of irrigation in arid regions, and the introduction of powered farm machinery (Heinberg and Bomford, 2009). Therefore, the need for cost-effective energy saving technologies or practices is being recognized by many governments and manufacturing industries, hence forcing them to review their energy policies.The energy analysis is based on the first law of thermodynamics, which expressed the principle of the conservation of energy and may be done by means of the process analysis method, in which the use of energy in every production step is traced backwards from the product to the primary sources. It provides no information about the irreversibility aspects of thermodynamic processes (Fadare et al., 2010). However, energy analysis has been criticised since it only includes the quantity of energy, and not its quality (Pellegrini and Oliveira, 2007). Whereas, exergy analysis is a thermodynamic analysis technique based on the combined principles of conservation of mass and energy together with second law of thermodynamics, which provides an alternative and illuminating means of assessing the locations, types and magnitudes of wastes and losses and to identify meaningful efficiencies of the system (Fadare et al., 2010). In exergy analysis the quality of the energy is taken into account. Exergy may be defined as: The maximum amount of useful work that may be extracted from a system, when it is reaching equilibrium with its environment (Szargut et al., 1988). Cumulative Exergy Demand (CExD) is an important tool in sustainability assessment of agricultural production. CExD is the total amount of renewable and non-renewable primary exergy demanded for the production of a product or service (Bösch et al., 2007).Exergy analysis methodologies have been applied to many researches such as: malt drink process (Fadare et al., 2010), sugarcane bagasse gasification (Pellegrini and Oliveira, 2007), and ethylene and propylene production process (Fabrega et al., 2010). However, the energy study does not play a strong role in agricultural production in terms of the aggregate exergy demand. CExD has not been studied in the production of apple production in Iran, therefore the present study is a combination of the life cycle inventory of apple production with the exergy concept which deals with the analysis of energy and energy consumption reduction opportunities from CExD index in apple production.
