The power industry development of China

Japan

Germany

the United States

South Korea and OECD was summarized in this paper. Moreover

the power generation efficiency

carbon emission and pollutant emission intensity were compared according to the power development status and composition of power generation modes in these countries. The results show that

China's coal-fired power generation efficiency has reached advanced level in the world

which is equivalent to Japan

higher than other countries. The gas power and heating has become the important factors affecting the thermal efficiency of thermal power plants. The carbon emission intensity of coalfired power in China is lower than that of developed countries such as Japan and Germany. Due to the low proportion of gas power

the carbon emission intensity of thermal power and power generation in China is higher than that of other countries. The emission intensity of air pollutants from thermal power plants in China is lower than that of other countries

and the emission intensity of electric pollutants from unit land area of other countries is higher than that of China

but the air environment quality is much better than that of China. In the next stage

China should continue to increase the proportion of gas power

increase the heating proportion of existing thermal power and energy-saving renovation efforts

for improving the thermal efficiency. Developing low carbon power generation technology and renewable energy technology are the main means to deal with carbon constraint. More attentions should be paid to the emission of pollutants from other industries.
