aThe continuity of these data series estimates may be affected by changing data sources and estimation methodologies. 
See the Technical Notes for each type of energy.		 fThere is a discontinuity in this time series between 1980 and 1981 due to the expanded coverage of renewable energy
sources beginning in 1981.
bTransportation 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.		 – – = Not applicable.
cLiquefied petroleum gases. Where shown, R = Revised data and (s) = Physical unit value less than 0.5 or Btu value less than 0.05.
dBeginning in 1993, fuel ethanol blended into motor gasoline is included in motor gasoline.  Fuel ethanol is also shown
separately to display the use of renewable energy by the transportation sector.  It is counted only once in the total.		 Note:  Totals may not equal sum of components due to independent rounding.
eIncurred in the generation, transmission, and distribution of electricity plus plant use and unaccounted for electrical
system energy losses.		 Sources:  Data sources, estimation procedures, and assumptions are described in the Technical Notes.
