11. Energy Consumption of the Powers, 1890-1938
The eastern to southeastern US and eastern to midwest contains one of the
largest deposits of bituminous coal in the geological area called the
'Pittsburgh Coal Seam'. The Appalachian Basin is one geographical area
of this geological location. NO other world power has such a large
concentration of bituminous coal, which burns very hot but very evenly, making
it suitable historically for homes, businesses, and mills / factories.
"The Appalachian Basin is one of the most important coal-producing regions in the world (figs. 1-3, table 1). Bituminous coal has been mined in the basin for the last three centuries, and the cumulative production is estimated at 34.5 billion short tons.
Annual production in 1998 was about 452 million short tons (Energy Information Administration, 1999); the basin's production is mostly in the northern (32 percent) and central (63 percent) coal regions. The coal is used primarily within the Eastern United States for electric power generation, but some of it is suitable for metallurgical uses."
"The USGS, in cooperation with the State geological surveys of Kentucky (KY), Maryland (MD), Ohio (OH), Pennsylvania (PA), Virginia (VA), and West Virginia (WV), has completed a digital coal resource assessment of five of the top-producing coal beds and coal zones in the northern and central Appalachian Basin coal regions (fig. 2). These are the Pittsburgh coal bed, the Upper Freeport coal bed, the Fire Clay and Pond Creek coal zones, and the Pocahontas No. 3 coal bed. Of the 93 billion short tons of original coal in these units, about 66 billion short tons remain
(table 1)."
