Energy-Efficient Lighting in China: Problems and Prospects
Guan Fu Min Marine University of Qingdao, c/o PRI 61 ZhanLiuGan Lu, Room 1213 Qingdao, China 266071 Evan Mills Center for Building Science, MS/90-3058 Lawrence Berkeley National Laboratory, Berkeley, California 94720, USA Qin Zhang Department of Industrial Engineering and Operations Research, University of California, Berkeley, California, 94720, USA Abstract China's choices of energy demand and supply technologies have a large impact on the world's energy market and the environment. Of its 920 billion kWh electric power production in 1993, it is estimated that 15% was used for lighting consumption (-120 billion kWh). This figure is likely to grow as the country develops, and so improving the energy efficiency of lighting in China could have a tremendous impact on China's energy consumption. This paper describes key components of the energy-efficient lighting industry from technology and marketing points of view. We identify a few key problem areas and their potentials for improvement. We identify a national savings potential of 40% by shifting to lamps with performance characteristics typical of current Western practice - but without changing the market share of various lamp types - and of 60% by adopting the best commercially available lamps in the West.
