本文综合分析和介绍了通过广泛采用新型电光源，到２０００年全国可实现年节电３００亿ｋＷ·ｈ；通过使流体机械中的水泵、风机进行经济运行和技术改造，也有３００亿ｋＷ·ｈ的节电潜力可挖；在宾馆、饭店等现代建筑物采用储冰式空调系统，可节约制冷用电１０％以上，减少制冷装机容量２０％以上；进行电力网的改造和加强其管理，努力降低线损。 This paper comprehensively analyzes and introduces that by adopting a new type of electric light source widely, by the year of 2000, the annual energy saving of 30 billion kW · h can be realized in the country. By making the economic operation and technological transformation of pumps and fans in fluid machinery, there are also 30 billion kW · h Of the potential savings can be tapped; in hotels, restaurants and other modern buildings using ice storage air conditioning system can save more than 10% of refrigeration electricity, reducing the installed capacity of refrigeration more than 20%; to transform the power grid and strengthen its management, efforts to reduce Line Loss.
