According to the International Energy Agency (IEA), global coal demand grew by 1% in 2017.
Global coal power generation increased around 3%, and accounted for about 40% of the additional power generation worldwide. Coal kept its share in the power mix at 38% after some years of decline.
Global coal demand in the next five years is expected to be stable, with declines in United States and Europe offset by growth in India and other Asian countries – though China will see a gradual decline in demand. In terms of the total energy mix, coal’s contribution will decline from 27% to 25%, mainly due to growth of renewables and natural gas.
