|Table 7.3. Average Quality of Fossil Fuel Receipts for the Electric Power Industry,|
|2002 through 2012|
|Period||Average Btu per Pound||Average Sulfur Percent by Weight||Average Ash Percent by Weight||Average Btu per Gallon||Average Sulfur Percent by Weight||Average Ash Percent by Weight||Average Btu per Cubic Foot|
|* = 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.
Coal includes anthracite, bituminous, subbituminous, lignite, and waste coal; coal synfuel and refined coal; and beginning in 2011, coal-derived synthesis gas. Prior to 2011 coal-derived synthesis gas was included in Other Gases.
Petroleum includes Petroleum Liquids and Petroleum Coke.
Petroleum Liquids includes distillate and residual fuel oils, jet fuel, kerosene, waste oil, and beginning in 2011, propane. Prior to 2011 propane was included in Other Gases.
Petroleum Coke includes petroleum coke-derived synthesis gas. Prior to 2011, petroleum coke-derived synthesis gas was included in Other Gases.
