|Table 7.2. Receipts and Quality of Coal Delivered for the Electric Power Industry, 2002 through 2012|
|Period||Receipts (Thousand Tons)||Average Sulfur Percent by Weight||Average Ash Percent by Weight||Receipts (Thousand Tons)||Average Sulfur Percent by Weight||Average Ash Percent by Weight||Receipts (Thousand Tons)||Average Sulfur Percent by Weight||Average Ash Percent by Weight|
|* = Value is less than half of the smallest unit of measure. (e.g., for values with no decimals, the smallest unit is 1 then values under 0.5 are shown as *.)
NM = Not meaningful due to large relative standard error or excessive percentage change.
W = Withheld to avoid disclosure of individual company data.
Bituminous coal includes anthracite, synthetic, and refined coal; and beginning in 2011, coal-derived synthesis gas. Prior to 2011 coal-derived synthesis gas was included in Other Gases.
See the Technical Notes for fuel conversion factors.
