1991年建材工业围绕“以节能降耗为中心,依靠技术进步,调整产业结构,提高企业的经济效益”这个指导思想,狠抓了节约能源工作,取得了一定成效。预计1991年全行业能源消耗为12000万吨标准煤,建材工业万元产值能耗可降为20.5吨标准煤(按1980年不变价计算),约比1990年下降4.3％;重点企业的水泥综合能耗比1990年下降1.63千克标煤/吨,平板玻璃综合能耗下降1.54千克标煤/重量箱,下降4.8％;重点水泥企业和重点玻璃企业 In 1991, the building materials industry focused on the guiding ideology of “focusing on energy saving and consumption reduction, relying on technological progress, adjusting industrial structure, and improving the economic efficiency of enterprises”, and paid close attention to the work of energy conservation and achieved certain results. It is estimated that in 1991, the energy consumption of the entire industry will be 120 million tons of standard coal, and the energy consumption per million yuan of building material industry production can be reduced to 20.5 tons of standard coal (calculated at constant price in 1980), which is approximately 4.3% lower than in 1990; the cement of key enterprises is integrated. Energy consumption decreased by 1.63 kg standard coal/ton compared with 1990, and the comprehensive energy consumption of flat glass decreased by 1.54 kg standard coal/weight box, a decrease of 4.8%; key cement companies and key glass companies
