Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. [2] Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian ...
Coal River was the first name given by British settlers to the Hunter River after coal was found there in 1795. In 1804 the Sydney-based administration established a permanent convict settlement near the mouth of the Hunter River to mine and load the coal, predetermining the town's future as a coal port by naming it Newcastle.
The name Carboniferous means "coal-bearing", from the Latin carbō ("coal") and ferō ("bear, carry"), and refers to the many coal beds formed globally during that time. [8] The first of the modern "system" names, it was coined by geologists William Conybeare and William Phillips in 1822, [9] based on a study of the British rock succession.
Coal forest of tree ferns and lycopod trees, in a 1906 artist's rendering. The coal forests seem to have been areas of flat, low-lying swampy areas with rivers flowing through from higher, drier land. [4] When the rivers flooded, silt gradually built up into natural levees. Lakes formed as some areas subsided, while formerly wet areas became ...
Due to the length of time it takes nature to form them, fossil fuels are considered non-renewable resources. In 2022, over 80% of primary energy consumption in the world and over 60% of its electricity supply were from fossil fuels. [5] The large-scale burning of fossil fuels causes serious environmental damage.

In 2013, Australia was the world's fifth-largest coal producer, after China, the United States, India, and Indonesia. However, in terms of proportion of production exported, Australia is the world's second largest coal exporter, as it exports roughly 73% of its coal production. Indonesia exports about 87% of its coal production. [60]
Wood was used as a feedstock during the early days (1820s - 1850s) of manufactured gas in certain areas of the United States, due to lack of development of coal resources. Wood was carbonized in a manner similar to coal; however, the gas evolved was markedly inferior to that of coal in lighting and heating qualities. Still very useful for lighting.
