2009: Thermal power accounts for about 80%, hydropower for about 16%, and the rest is wind, nuclear, etc. We are now vigorously developing clean energy, so the proportion of thermal energy will decrease, and the trend is to increase the proportion of clean energy such as hydropower. (Internet search China's electricity supply structure) In 2010, the annual electricity consumption was 4 trillion kWh. (Internet search: China's annual electricity consumption) It is not possible to stop coal-fired power (thermal power): 1. The development of other clean energy requires a process. The construction cycle of a hydroelectric power station lasts from 5 to 20 years. Although many power plants can be built at the same time, it also takes time. Site selection requirements fornuclear energy are relatively strict, safety must be considered, and development will not be too rapid. Wind energy reserves are limited. 2. Thermal energy has advantages that other electric energies do not have: stability and few restrictions on plant site conditions. Most hydropower is seasonal, and electricity production varies significantly between wet and dry periods. Wind power is also limited by the uncertainty of wind power. 3. Linked to the local economy. This involves the sale of coal companies as well as the operation and development of power companies. By shutting down coal-fired power, coal mines lost huge, high-quality, stable customers. Electric power giants who mainly focus on thermal energy cannot embark on the development of other sourcess energy if they don't have food to eat, they definitely won't. 4. Disadvantages of nuclear energy. The cost of power plants is higher than that of thermal energy. There are no international conclusions on the safety of nuclear energy. As a large amount of cooling water is required, it can only be built in areas where water is abundant and seismic intensity is low. The biggest problem is that the treatment of nuclear waste currently involves landfilling or returning it for disposal. Landfilling is the stupidest method and environmental pollution is inevitable; Recycling requires specialized technology, equipment and processing plants. Current processing capacity is too low and new construction and expansion will take time. (Internet search: Disadvantages of nuclear energy,disposal of nuclear waste)
