China is the largest producer and consumer of coal and the largest user of coal-generated electricity in the world. The share of coal in the Chinese energy mix declined to 55% in 2021 according to the US Energy Information Agency.
The Chinese central government has clamped down on the pace of new construction of coal plants and shifted to renewable, nuclear and natural gas sources. At the same time, coal consumption reached new heights in China with carbon dioxide emissions from coal-fired electricity production estimated to top 4.5 billion tonnes in 2022. Reuters noted in 2022, "China is set to delight and depress climate trackers in equal measure in 2022 by setting new global records in both clean power utilisation and coal-fired electricity emissions." Solar and wind generated electricity surged by over 30% and 25% respectively during the period from January to October 2022 compared to the same period in 2021. Despite central government attempts to clamp down on construction and shifting demand in the market to renewable, nuclear and natural gas sources, 43 coal power units were announced in the first half of 2021 according to the Centre for Research on Energy and Clean Air in August 2021.
In September 2021, China pledged to end financing of coal power plants abroad. A study by Centre for Research on Energy and Clean Air in April 2022 stated at least 15 overseas coal power plants had been cancelled since the announcement, while 18 projects which had secured financing and necessary permits could enter into construction.
During the 2021 energy crisis in China, this dependency on coal units, depletion of reserves, increasing import prices, and slowdowns of shipment and production lead to widespread shutdowns of industrial energy use.
Ancient people in current China started using coal around 6,000 years ago. Historians suspects that the Chinese were involved in the surface mining of coal around 3490 BC, pioneering the pre-modern world. Fushan mine uses to be pointed out as the earliest coal mine in the ancient world and started around 1000 BC.

The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products. In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas desulfurization sludge, that contain mercury, uranium, thorium, arsenic, and other heavy metals.
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide there are over 2,400 coal-fired power stations, totaling over 2,000 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and the most early deaths, mainly from air pollution. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler.
Coal mining is the process of extracting coal from the ground or from a mine. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a 'pit head'. In Australia, "colliery" generally refers to an underground coal mine.
