[email protected] Abstract: Industry represents one of the most interesting sectors when analysing Croatian final energy demand. Croatian industry represents 20% of nation’s GDP and employs 25% of total labour force making it a significant subject for the economy. Today, with around 60 PJ of final energy demand it is the third most energy intensive sector in Croatia after transport and households. Implementing mechanisms that would lead to improvements in energy efficiency in this sector seems relevant. Through this paper, long-term energy demand projections for Croatian industry will be shown. The central point for development of the model will be parameters influencing the industry in Croatia. Energy demand predictions in this paper are based upon bottom-up approach model. IED model produces results which can be compared to Croatian National Energy Strategy. One of the conclusions shown in this paper is significant possibilities for energy efficiency improvements and lower energy demand in the future.
