These days, limited energy resources, and also the cost of investment in new and renewable energy is very costly and uneconomical. In the industrial sector, especially energy-intensive industries such as steel, finding appropriate solutions to update the technology, production and reduce energy consumption in this sector is very important. The main aim of this study is the identification and ranking the methods to reduce the cost of energy consumption in the steel industry with the MCDM approach, that Mobarakeh Steel Company is the largest firm economic basis in our country. The population of this research, experts in Mobarakeh Steel Industries of Esfahan city, which are composed of 10 experts. In this study, three questionnaires for screening of selected indicators, prioritize important measure known and set relationship among parameters using fuzzy Dematel approach and determine the extent of the relationships between variables using network analysis process (ANP), is used. The outputs of this research show that the steelmaking and casting, steelmaking, blast furnace, accumulation and withdrawal, carriage, coking, iron making, rolling, agglomeration and converter have the most energyconsumption
