Coal Geology Geoscience Australia
Coal is broadly separated into brown and black which have different thermal properties and uses. Brown coal lignite has a low energy and high ash content. Brown coal is unsuitable for export and is used to generate electricity in power stations located at or near the mine. Black coal is harder than brown coal and has a higher energy content.

Chapter 7 Coal - Pennsylvania State University
States has far more coal than gas and petroleum compare Figures 7-1 8-1 and 9-1. This suggests that when supplies of gas and petroleum become scarce it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal There are many uncertainties involved in making such an .
