世界能源平均利用效率50.32%,我国36.81%,印度39%,美国51%,日本56%,丹麦72%。我国年产量44亿吨标准煤,按照36.81%的比例计算,有效利用为16亿吨,28亿吨变成了余热、废热,变成了雾霾、烟尘,这是我国能源行业的现实。国家能源局规划到2020年地热能开发利用量达到5000万吨标准煤,形成完善的地热能开发利用体系和产业体系。近几年,政府也出台了一系列的产业政策和财政政策支持行业发展。在住建部大力推广的绿色建筑、低碳建筑、可再生能源建筑、超低能耗建筑中,地源热泵被作为一项成熟的节能技术,以节能、高效、可替
The world’s energy use efficiency was 50.32%, 36.81% in China, 39% in India, 51% in the United States, 56% in Japan and 72% in Denmark. China’s annual output of 44 tons of standard coal, calculated according to the proportion of 36.81%, the effective use of 1.6 billion tons, 2.8 tons into waste heat, waste heat, into a haze, smoke and dust, which is the reality of China’s energy industry. National Energy Administration plans to 2020 geothermal energy utilization reached 50 million tons of standard coal, forming a perfect geothermal energy development and utilization system and industrial system. In recent years, the government has also introduced a series of industrial policies and fiscal policies to support the development of the industry. In the green building, low-carbon building, renewable energy building and ultra-low energy building vigorously promoted by the Ministry of Housing and Urban-Rural Development, ground source heat pump is used as a mature energy saving technology to save energy,
