%X The nonferrous metals industry is a typical high energy-consuming industry and a major sector for future energy saving and emissions reduction in China. At first, effects of energy saving and energy consumption reduction of the nonferrous metals industry during the 11th Five-Year Plan were evaluated, and the estimation results of the initial data indicate that the energy intensity of the nonferrous metals industry in 2009 decreased by 22.34% compared to that in year 2005. Major technical targets were noticeably enhanced. According to the energy conservation plan of the nonferrous metals industry, industrial energy efficiency and per-unit product energy consumption goals were met. On the other hand, energy saving achievements of the nonferrous metals industry still needs to be consolidated based on the situation in the first half of 2010. Then, development trends of nonferrous metals industrial energy conservation were analyzed. Some conclusions were drawn. Technological progress is still the main content of nonferrous metals industrial energy saving and energy consumption reduction during the 12th Five-Year Plan, but technology reaching or approaching advanced international standards will lead to decreasing energy saving potential relying solely on technology import. Therefore, the nonferrous metals industry must strengthen research & development and innovation of energy technologies and improve energy-saving technological innovation capacity in the future. Recycling and reusing of wasted metals will play an increasingly important role in energy saving of the nonferrous metals industry. At a rough estimate, annual energy saving of recycling and reusing of wasted metals in 2015 will exceed 20 million tce according to current technologies. Even considering technology improvement in the production of primary nonferrous metals, annual energy saving of recycling and reusing of wasted metals in 2015 will still approach 15 million tce. The circular economy can effectively reduce energy consumption and improve economic benefits through muti-industry cooperative development and has double efforts. Developing the circular economy would boast great potential in nonferrous metals industrial energy saving. Recycling and reusing of wasted metals and developing the circular economy will be the important ways of future energy conservation in the nonferrous metals industry. At end of this paper, some policy advice was proposed. Future energy conservation policy of the nonferrous metals industry will focus on improving mechanisms of industrial technology upgrading, optimizing product mix, cultivating energy-saving technological innovation environment, promoting a healthy development of the secondary non-ferrous metals industry, and making energetic efforts to develop the circular economy.
