Coal has dominated the world energy scenario since the Eighteenth century, up to 1970 and in 2013 it accounts for approximately 28.9% of the primary consumption of energy (Source: International Energy Agency (IEA) – Key World Energy Statistics 2015). In the years between 2003 and 2006, it is estimated that coal demand increased almost 67%; China accounted for 73% and if we also consider India, the percentage rises to 82%. China is the leading producer and consumer in the world: in 2015 coal consumption in China amounts to 1920 million toe per year, with a production of 1827 million toe per year (Source: BP Statistical Review of World Energy 2016).
The greatest limit of coal is that it is the most polluting source of energy and it negatively affects the state of the climate. When compared to natural gas, production of one kilowatt-hour of electricity from coal generates  more than twice the amount of nitrogen oxide, eight times the amount of heavy metals, ten times the amount of fine dust, and it also produces a large amount of sulphur oxides.
