The development path of the power industry has attracted much attention and heated discussion, since President Xi Jinping announced China's carbon peak and carbon neutrality targets. It points out that carbon peak includes peak time and peak value, and carbon neutrality is not zero emission of CO_2, starting from the basic concept of carbon peak and carbon neutrality. Based on the path analysis of carbon peak and carbon neutralization in developed countries, the similarities and differences between China and developed countries are obtained. It will be harder for China to reach a carbon peak and become carbon neutrality. Three important measures are proposed, the first is with energy-saving and burning with blending as the lead, to retain no less than 800 million kW thermal power units. The second is with low carbon energy as the key, to develop wind and solar power generation. The third is with energy storage and carbon capture as the supplement, to ensure the stability of electric power system. According to the China's practical situation that the fossil energy is with rich coal, poor oil and little gas, the development of hydro-power resources is basically completed, and the site selection of nuclear power stations is more difficult, it is estimated that the CO_2 emission from China's thermal power industry during the carbon peak period is about 4.7 billion tons, the allowable CO_2 emission is about 1.35 billion tons during the period of carbon neutrality. And China's installed power capacity will be 6.43 billion kW, of which wind and solar power generation is 5 billion kW, nuclear power 200 million kW and hydro-power 430 million kW, waste heat, pressure and gas generated electricity of 50 million kW, biomass generated electricity of 120 million kW, gas generated electricity of 100 million kW, coal-fired generated electricity of 530 million kW. The non-fossil energy generated electricity installed capacity accounts for 90.2%, electricity generation accounts for 85.3%. China's power industry emits about 1.521 billion tons of CO_2 during the period of carbon neutrality, of which 1.318 billion tons are emitted by the thermal power sector, less than the allowable emissions.
