United States and coal

Coal Resources

The United States coal resource base is the largest in the world. According to expert reports commissioned by the World Energy Council in 2011, there is a proved amount in place of some 442 billion tonnes (based on the Energy Information Administration’s ‘Demonstrated Reserve Base’). This total is comprised of 241.6 billion tonnes of bituminous coal (including anthracite) with a maximum deposit depth of 671 m and minimum seam thickness of 0.25 m; 161.8 billion tonnes of sub-bituminous (at up to 305 m depth and 1.52 m minimum seam thickness) and 39.0 billion tonnes of lignite (at up to 61 m depth and 0.76 m minimum seam thickness).[1]

The reported proved recoverable reserves amount to 237.3 billion tonnes, equivalent to about 28% of the global total. They comprise 108.5 billion tonnes of bituminous coal (including anthracite), 98.6 billion tonnes of sub-bituminous and 30.2 billion tonnes of lignite. The overall ratio of proved recoverable reserves to the proved amount in place is 0.54. [1]

WEC Member Committee reports enormous quantities of coal as inferred resources, being the difference between Remaining Identified Resources and the Demonstrated Reserve Base: in total these come to well over a trillion tonnes, composed of 418 billion tonnes of bituminous, 268 billion sub-bituminous and 391 billion lignite. These estimates are derived from a US Department of the Interior study of coal resources as at 1 January 1974, but are regarded as still providing valid indications of the magnitude of the USA’s additional coal resources. Assuming a similar recovery ratio for such resources as for those reported as proved, the US Member Committee estimates the recoverable portion as amounting to some 653 billion tonnes, comprised of 188 bituminous, 163 sub-bituminous and 302 lignite.[1]

Enormous additional (hypothetical) coal resources are also reported. The amounts involved comprise 698 billion tonnes of bituminous coal, 1 036 billion tonnes of sub-bituminous and 296 billion tonnes of lignite, giving a total of some 2 trillion tonnes.[1]

Coal exports

In 2007, the United States exported almost 60 million tons of coal. One industry analyst estimated that the amount would rise to 80-90 million tons in 2008 and 100 million tons in 2009. Through June of this 2008, producers sent 40.4 million tons overseas, a 57 percent increase over the same period in 2007.[2]

In May 2011, Reuters reported that total U.S. coal exports could amount to around 100 million tons (91 million tons) in 2011, according to analysts, leaving only Australia and Indonesia above the U.S. in world coal export rankings, and putting the U.S. above Russia, Colombia and South Africa.[3]

Coal production

According to the U.S. Energy Information Agency, U.S. coal production totaled:[4]

  • 1.17 billion short tons in 2008;
  • 1.074 billion tons in 2009;
  • 1.084 billion tons in 2010; and
  • 1.08 billion tons in 2011.
