Abstract:A methodology for the energy efficiency benchmarking of steel industry among different countries was put forward, and the key factors such as boundary definitions, energy efficiency index, energy conversion factors, EAF share, etc. were discussed in the methodology. Applying the above methodology, the energy efficiencies of steel industries between China and the U.S. were analyzed and compared. It is shown that, viewed from the whole steel industry, the energy intensity of China is 24.30kg/t-crude steel higher than that of the U.S. based on the same conditions of boundary, energy conversion factors and EAF share, while viewed from the energy efficiencies of the key steel enterprises of China, the energy intensity of Chinese steel enterprises is 59.70kg/t-crude steel lower than that of the U.S..
