[21] Subbituminous coal can form at temperatures as low as 35 to 80°C (95 to 176°F) while anthracite requires a temperature of at least 180 to 245°C (356 to 473°F). [22] One theory suggested that about 360 million years ago, some plants evolved the ability to produce lignin, a complex polymer that made their cellulose stems much harder and more woody. The ability to produce lignin led to the evolution of the first trees. But bacteria and fungi did not immediately evolve the ability to decompose lignin, so the wood did not fully decay but became buried under sediment, eventually turning into coal. About 300 million years ago, mushrooms and other fungi developed this ability, ending the main coal-formation period of earth's history. [28] [29] Although some authors pointed at some evidence of lignin degradation during the Carboniferous, and suggested that climatic and tectonic factors were a more plausible explanation, [30] reconstruction of ancestral enzymes by phylogenetic analysis corroborated a hypothesis that lignin degrading enzymes appeared in fungi approximately 200 MYa.

Some coal miners are concerned their jobs may be lost in the transition. [235] A just transition from coal is supported by the European Bank for Reconstruction and Development. [236] Bioremediation Coal continues to arrive on beaches around the world from both natural erosion of exposed coal seams and windswept spills from cargo ships. Many homes in such areas gather this coal as a significant, and sometimes primary, source of home heating fuel. [71] Chemistry Composition The calculation based on the above is simply 1 (kW output from your heater) x 13p (kWh charge from your electricity supplier) = 13p per hour.

Coke is a solid carbonaceous residue derived from coking coal (a low-ash, low-sulfur bituminous coal, also known as metallurgical coal), which is used in manufacturing steel and other iron products. [76] Coke is made from coking coal by baking in an oven without oxygen at temperatures as high as 1,000°C, driving off the volatile constituents and fusing together the fixed carbon and residual ash. Metallurgical coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. [77] The carbon monoxide produced by its combustion reduces hematite (an iron oxide) to iron.

One likely tectonic factor was the Central Pangean Mountains, an enormous range running along the equator that reached its greatest elevation near this time. Climate modeling suggests that the Central Pangean Mountains contributed to the deposition of vast quantities of coal in the late Carboniferous. The mountains created an area of year-round heavy precipitation, with no dry season typical of a monsoon climate. This is necessary for the preservation of peat in coal swamps. [32] One of the earliest known impacts of coal on the water cycle was acid rain. In 2014 approximately 100 Tg/S of sulfur dioxide (SO 2) was released, over half of which was from burning coal. [155] After release, the sulfur dioxide is oxidized to H 2SO 4 which scatters solar radiation, hence its increase in the atmosphere exerts a cooling effect on climate. This beneficially masks some of the warming caused by increased greenhouse gases. However, the sulfur is precipitated out of the atmosphere as acid rain in a matter of weeks, [156] whereas carbon dioxide remains in the atmosphere for hundreds of years. Release of SO 2 also contributes to the widespread acidification of ecosystems. [157] A 2017 study in the Economic Journal found that for Britain during the period 1851–1860, "a one standard deviation increase in coal use raised infant mortality by 6–8% and that industrial coal use explains roughly one-third of the urban mortality penalty observed during this period." [144] In China, improvements to air quality and human health would increase with more stringent climate policies, mainly because the country's energy is so heavily reliant on coal. And there would be a net economic benefit. [143]For particularly draughty buildings, a halogen heater is the best heating appliance you can get. Its infrared heat focuses on heating objects rather than the surrounding air. And that’s perfect when you’re in a building with a constant flow of cold air — a small heater would struggle to keep the entire air mass at the desired temperature.

Outcrop coal was used in Britain during the Bronze Age (3000–2000 BC), where it formed part of funeral pyres. [55] [56] In Roman Britain, with the exception of two modern fields, "the Romans were exploiting coals in all the major coalfields in England and Wales by the end of the second century AD". [57] Evidence of trade in coal, dated to about AD 200, has been found at the Roman settlement at Heronbridge, near Chester; and in the Fenlands of East Anglia, where coal from the Midlands was transported via the Car Dyke for use in drying grain. [58] Coal cinders have been found in the hearths of villas and Roman forts, particularly in Northumberland, dated to around AD 400. In the west of England, contemporary writers described the wonder of a permanent brazier of coal on the altar of Minerva at Aquae Sulis (modern day Bath), although in fact easily accessible surface coal from what became the Somerset coalfield was in common use in quite lowly dwellings locally. [59] Evidence of coal's use for iron-working in the city during the Roman period has been found. [60] In Eschweiler, Rhineland, deposits of bituminous coal were used by the Romans for the smelting of iron ore.
