The Powder River Basin (PRB), located in the western United States, is a coal mining region that has evolved throughout the half century since the first largescale mine began in the 1970s, as shown in Fig. related to commodity pricing, high inflationary periods and, more recently, low demand, associated with power producers switching from coal to natural gas or renewable energy ...

Coal companies in the Powder River Basin in Montana and Wyoming can extract more than 10 times as much coal per employee hour as coal companies operating in the Appalachian Basin. (see Figure 1)
The first coal basin to be evaluated was the Powder River Basin (PRB) in Wyoming and Montana, because it has been the most productive coal basin in the United States over the past 25 years. The results of the PRB assessment were published in Professional Paper 1809 in 2015.
The estimate assumed that Powder River Basin coal generates 8,500 BTUs per pound, and that one million BTUs would produce pounds of CO2, consistent with Department of Energy figures. The final calculation was 199 million tons of CO2 per year in "direct" emissions from the coal exports.

Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the region's total coal output in 1992. Subbituminous coal in Wyoming's Powder River Basin, the principal source of this rank of coal, has an emission factor of pounds of carbon dioxide per million Btu.

The most important distinction between this Powder River Basin coal assessment and other, prior assessments, was the inclusion of mining and economic analyses to develop an estimate of the portion of the total resource that is potentially recoverable, not just the original (inplace) resources. ... The USGS Energy Resources Program research ...
The Energy Information Administration estimates (as of October 2022) that in 2021, CO 2 emissions from burning coal for energy accounted for about 20% of total energyrelated CO 2 emissions and for nearly 60% of total CO 2 emissions from the electric power sector. In the past, fly ash was released into the air through the smokestack ...
In the Powder River Basin, for example, coal is of insufficient thermal maturity to have generated thermogenic hydrocarbons, and geochemical data indicate that all produced gas is effectively of biogenic origin [54], [55]. Methanogenesis occurs along two major metabolic pathways: methyltype fermentation and CO 2 reduction shown in Fig.

The Powder River Basin coal boom started in the 1970s. The biggest mine by production volume, Black Thunder, opened in 1977. The company town of Wright sprang up at nearby Reno Junction, beginning with the 108unit Cottonwood Mobile Home Park. As of 2012 there are 13 operating coalmines in the Powder River Basin in Wyoming.
The amount drops even more drastically when the coal's quality is factored in and compared against current prices. When the USGS data was first compiled, in 2013, Powder River Basin coal was selling for a ton, resulting in about 23 billion tons being designated as economicallyrecoverable. ... Powder River Basin coal was selling for 10. ...
Arch Resources' Coal Creek mine in the Powder River Basin, pictured here in December of 2019, is slated for closure in 2022. (Dustin Bleizeffer) The reality of a permanently shrinking Powder River Basin coal industry came into sharper focus on Tuesday with Arch Resources announcing it is speeding up preparations to close its Coal Creek mine.
Coal in the Powder River Basin. The Powder River Basin in the Red Desert stretches for more than 14 million acres from the peaks of Wyoming's Bighorn Mountains to the Yellowstone River in eastern Montana. It provides premier habitat for elk, mule deer, pronghorn antelope, wild turkeys, and the threatened greater sagegrouse in places like Otter ...
