The US coal resource base is the largest in the world.
Proved recoverable reserves of 250 billion tonnes
are equivalent to about 25% of the global total. The
US Department of Energy/Energy Information Administration’s
(EIA) demonstrated reserve base (DRB), (corresponding
to the WEC category of "proved amount in place") is
457 billion tonnes (504 billion short tons), of which
bituminous coal (including anthracite) constitutes
about 55%, sub-bituminous 36% and lignite 9%. Coal
deposits are widely distributed, being found in 38
states and underlying about 13% of the total land
area. The Western Region (notably Montana and Wyoming)
accounts for about 47% of the DRB, the Interior Region
(in particular, Illinois and Kentucky) for 31% and
the Appalachian Region (chiefly West Virginia, Pennsylvania
and Ohio) for 21%. Bituminous coal reserves are recorded
for 27 states, whereas only 8 states have sub-bituminous
reserves, of which 90% are located in Montana and
Wyoming.
Total proved recoverable reserves represent about
55% of the proved amount of coal in place. Overall,
almost 27% of the recoverable reserves of bituminous
coal (including anthracite) is surface-mineable, compared
with 44% of sub-bituminous reserves and 100% of those
of lignite.
US coal output is the second highest in the world,
after China, and accounted for about 23% of global
production in 1999. Coal is the USA’s largest single
source of indigenous primary energy; power stations
and CHP plants accounted for over 92% of domestic
coal consumption in 1998. Coal exports amounted to
53 million tonnes in 1999: the USA remains one of
the world’s leading suppliers of coking coal and other
bituminous grades.
