What proportion of photovoltaic power generation currently accounts for in my country's total p

2009: Thermal power accounts for about 80%, hydropower accounts for about 16%, and the rest is wind power, nuclear power, etc. Now we are vigorously developing clean energy, so the proportion of thermal power will decrease, and the trend is that the proportion of clean energy such as hydropower will increase. (Internet search China’s power supply structure) In 2010, the annual electricity consumption was 4 trillion kWh. (Internet search China’s annual electricity consumption) It is not feasible to stop coal power (thermal power): 1. The development of other clean energy requires a process. The hydropower construction cycle is 5 to 20 years. Although many power stations can be built at the same time, it also takes time. The site selection requirements for nuclear power are relatively strict, safety needs to be considered, and the development will not be too fast. Wind power energy reserves are limited. 2. Thermal power has advantages that other electric power does not have: stability and few restrictions on plant site conditions. Most hydropower is seasonal, and power generation varies greatly between wet and dry periods. Wind power is also limited by the uncertainty of wind energy. 3. Related to local economy. This involves the sales of coal companies and the operation and development of power companies. By shutting down coal power, coal mines have lost huge stable and high-quality customers. Electric power giants that mainly focus on thermal power cannot squeeze into the development of other energy sources. If they have no food to eat, they will definitely not do it. 4. Disadvantages of nuclear power. The cost of power plants is higher than thermal power. There is no conclusion internationally on the safety of nuclear power. Since a large amount of cooling water is required, it can only be built in areas with abundant water and low seismic intensity. The biggest problem is that the treatment of nuclear waste is currently landfilling or turning back for disposal. Landfilling is the stupidest method and pollution to the environment is inevitable; recycling requires specialized technology, equipment and treatment plants. The current processing capacity is too weak, and new construction and expansion will take time. (Internet search: Disadvantages of Nuclear Power, Nuclear Waste Disposal)
