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
