Wyoming and coal - SourceWatch

The coal is highly desirable because of its low sulfur levels. On average, Wyoming coal contains 0.35 percent sulfur by weight, compared with 1.59 percent for Kentucky coal and 3 to 5 percent for other eastern coals such as West ia. Although Wyoming coal may have less sulfur, it also has a lower "heat rate" or fewer Btu's of energy.
