Coal Basics

Why does coal matter?

The United States has more estimated recoverable coal reserves than any other nation except China and is a net exporter of coal. In 2017, coal provided 30% of the electricity consumed across the country, and 93% of coal consumed in the United States was used to generate electricity.[3]
