The Importance Of Coal In Achieving Energy Independence For The United States

The new international fact of life that has emerged in the 70's is that foreign energy sources can no longer be considered either reliable or low in price. As a result, the United States is turning its full attention to its domestic energy resources. The figures about proved domestic reserves are often used to reassure us about the Nation's energy future: assuming a 50 percent recovery factor, there are at least 219 billion tons of recoverable bituminous coal and lignite, of which 31 percent is available by surface methods; proved reserves of crude petroleum and natural gas liquids total 34.3 billion barrels and 6.4 billion barrels, respectively. There is also about 4 billion tons of recoverable anthracite coal, a premium low-sulfur fuel of high heating value, which is all but priced out of the market because of the high costs of producing it. Total fossil fuel resources are even larger, although there are no guarantees concerning how much might become usable, and when, and at what cost. The figures, however, are impressive. They include the equivalent of about 200 billion barrels of oil potentially recoverable from high grade oil shale; 100 billion barrels in "heavy oil" deposits; and the equivalent of 25 to 35 billion barrels of oil in domestic deposits of "tar sands," and substantial quantities of conventional oil and gas resources. There is also the prospect of a significant increase in electric power generation
