Industrial energy systems are complicated networks; where changes in one process influence its neighboring processes. Saving energy in one unit does not necessarily lead to energy savings for the total system. A study has been carried out on the possibility to use the exergy concept in the analysis of industrial energy systems. The exergy concept defines the quality of an amount of energy in relation to its surrounding; expressing the part that could be converted into work. The study consists of literature studies and general evaluations; an extensive case study and an interview study. In the latter it was found that non technical factors are major obstacles to the introduction of exergy.
