The coal supply shortage was the result of production and consumption dynamics over the last several years. Between 2017 to 2019, coal production declined by 9%, mostly because of decreasing global coal demand and increasing competition from natural gas. coal production decreased by an additional 24% in 2020 because of a coal surplus in ...
