Gas Energy Reserves—Oil Coal and Uranium - Coal

nominal billion information oil

The EIA estimated U.S. coal reserves at 497.7 billion short tons on January 1, 2003. (See Table 7.5.) About 42% of this, 211.5 billion short tons, is underground bituminous coal. Montana, Illinois, and Wyoming have the largest coal reserves.

In addition to untapped coal reserves, large stockpiles of coal are maintained by coal producers, distributors, and major consumers (such as electric utility companies and industrial plants) to compensate for possible interruptions in supply. Although there is little seasonal change in demand for coal, supply can vary owing to factors such as coal miners' strikes and bad weather. According to the EIA's Annual Energy Review 2003 (2004), coal stockpiles totaled 163.8 million short tons in 2003. Electric utilities

Notes: The information reported for 1965 and prior years is not strictly comparable to that in more recent surveys. Average cost is the arithmetic mean and includes all costs for drilling and equipping wells and for surface-producing facilities. Wells drilled include exploratory and development wells; excludes service wells, stratigraphic tests, and core tests.

Data represent known measured and indicated coal resources meeting minimum seam and depth criteria, in the ground as of January 1, 2003. These coal resources are not totally recoverable. Net recoverability with current mining technologies ranges from 0 percent (in far northern Alaska) to more than 90 percent. Fifty-four percent of the demonstrated reserve base of coal in the United States is estimated to be recoverable.
