Coal is the most abundant fossil fuel on the planet, and widely used as the source of energy in thermal power stations and is a relatively cheap fuel. Coal is an impure fuel and produces more greenhouse gas and pollution than an equivalent amount of petroleum or natural gas. For instance, the operation of a 1000-MWe coal-fired power plant ...
China is the largest producer of coal in the world. It is the world's largest energy consumer, and coal in China supplies 60% of its primary energy. However two fifths of China's coal power stations are estimated to be loss-making. [116] Air pollution from coal storage and handling costs the US almost 200 dollars for every extra ton stored, due ...
A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%. [5] Typical coal-based power plants operating at steam pressures of 170 bar and 570 °C run at efficiency of 35 to 38%, [6] with state-of-the-art fossil fuel plants at 46% efficiency. [7] Combined-cycle systems can reach higher values.
Coal tar and coal tar sludges are frequently denser than water and are present in the environment as a dense non-aqueous phase liquid. In the UK, a number of former gasworks sites have been redeveloped for residential and other uses (including the Millennium Dome), being seen as prime developable land within the confines of city boundaries.
By the late 20th century, coal was, for the most part, replaced in domestic as well as industrial and transportation usage by oil, natural gas or electricity produced from oil, gas, nuclear power or renewable energy sources. By 2010, coal produced over a fourth of the world's energy. [5] Since 1890, coal mining has also been a political and ...

In 2021, coal supplied 9.5 quadrillion British thermal units (2,800 TWh) of primary energy to electric power plants, [4] which made up 90% of coal's contribution to U.S. energy supply. [5] Utilities buy more than 90% of the coal consumed in the United States. [6] There were over 200 coal powered units across the United States in 2024.
