Q&A: Stanford expert explains why we continue burning coal for
Coal's share of the U.S. electricity supply has dropped from 50 percent to under 30 percent in the past 15 years. That's largely because of the shale gas revolution, which suddenly made natural gas cheaper than coal for generating electricity. Still, 30 percent of the U.S. electricity supply is a lot of coal. Global coal use continues to ...

What are the types of coal? | U.S. Geological Survey
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 carbon-rich, 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, …
