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.get price
