aTransportation use of natural gas is gas consumed in the operation of pipelines, primarily in compressors, and, since 1990, is also natural gas consumed as vehicle fuel. Where shown, R = Revised data and (s) = Value less than 0.05 million nominal dollars. bLiquefied petroleum gases. Where shown, — = No consumption, including cases where adjustments were made.  See explanation of adjustments in Section 7 of the Technical Notes. cFor expenditures, includes fuel ethanol blended into motor gasoline, beginning in 1993. Note:  Expenditure totals may not equal sum of components due to independent rounding. dFor 1981 through 1992 expenditures, total includes ethanol blended into motor gasoline that is not shown in the motor gasoline column. Sources:  Data sources, estimation procedures, and assumptions are described in the Technical Notes.
