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 1988 and 1989 due to the expanded coverage of renewable
energy sources beginning in 1989.
