Global coal use was 8.3 billion tonnes in 2022, [14] and is set to remain at record levels in 2023. [15] To meet the Paris Agreement target of keeping global warming below 2 °C (3.6 °F) coal use needs to halve from 2020 to 2030, [16] and "phasing down" coal was agreed upon in the Glasgow Climate Pact.
Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. Lignite combustion produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, lignite is the most harmful coal to human health. [3]
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.
Bituminous coal was once extensively used for home heating in the US. However, bituminous coal is a relatively dirty fuel. The reduction in the use of bituminous coal between 1945 and 1960 is estimated to have saved at least 1,923 lives of all ages and 310 infant lives per winter month. [62]
Coal-upgrading technology refers to a class of technologies developed to remove moisture, and certain pollutants from low rank coals such as sub-bituminous coal and lignite and raise their calorific values. Companies in Australia, Germany, and the United States are the principal drivers of this research, development, and commercialization.
The History of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.

Solid fuels have been used by humanity for many years to create fire. Coal was the fuel source which enabled the Industrial Revolution, from firing furnaces, to running steam engines. Wood was also extensively used to run steam locomotives. Both peat and coal are still used in electricity generation today. The use of some solid fuels (e.g. coal ...
