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. iNet interstate flow of electricity is the difference between the amount of energy in the electricity sold within a State (including associated losses) and the energy input at the electric utilities within the State.  A positive number indicates that more electricity (including associated losses) came into the State than went out of the State during the year; conversely, a negative number indicates that more electricity (including associated losses) went out of the State than came into the State. bPhysical unit data include supplemental gaseous fuels (SGF) for all years; Btu data exclude SGF for 1980 forward. jFrom 1981 through 1992, includes fuel ethanol blended into motor gasoline but not shown in the motor gasoline column. cLiquefied petroleum gases. kThere is a discontinuity in this time series between 1988 and 1989 due to the expanded coverage of renewable energy sources beginning in 1989. dBeginning in 1993, includes fuel ethanol blended into motor gasoline. kWh = Kilowatthours.  – – = Not applicable. e"Other" is the subtotal of 16 petroleum products consumed in the industrial sector.  See a full description in the Technical Notes, Section 4, "Other Petroleum Products." Where shown, R = Revised data and (s) = Physical unit value less than +0.5 and greater than -0.5 or Btu value less than +0.05 and greater than -0.05. fConventional hydroelectric power.  Includes pumped-storage hydroelectricity, which cannot be separately identified, from 1960 through 1989. Note:  Totals may not equal sum of components due to independent rounding. gWood and waste.  Prior to 2001, includes non-biomass waste. Sources:  Data sources, estimation procedures, and assumptions are described in the Technical Notes. h"Other" is geothermal, wind, photovoltaic, solar thermal energy, and net imports of electricity.
