United States: Despite electricity demand increasing in the United States, coalfired generation fell by almost 8% in 2022, reversing a 15% increase in 2021. The decrease in coal output was balanced by an increase in generation from natural gas and strong growth in renewables. As a result, coal's share of total global generation remained around ...

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...
