    • Beginning in 2001, "Biomass" is revised to remove non-renewable waste (municipal solid waste from non-biogenic sources, and tire-derived fuels).

Changes in Annual Energy Review 2004

  • Annual Energy Review 2004 Release: August 19, 2005

    • Hydroelectric Pumped Storage:
    • Tables 1.2, 1.3, 2.1f, 8.4a, and 8.4b no longer include the energy consumed by hydroelectric pumped storage plants. The change was made because most of the electricity used to pump water into elevated storage reservoirs is generated by plants other than pumped-storage plants; thus, the associated energy is already accounted for in other data columns in the tables (such as conventional hydroelectric power, coal, and natural gas). Because the quantities removed were negative values (derived as pumped-storage facility production minus energy used for pumping, where energy used for pumping is usually larger), the overall effect of the change is to raise U.S. total energy consumption slightly from 1990 forward.
    • Electricity End Use:
    • The "Commercial" and "Other" columns previously shown under "Retail Sales" in Table 8.9 are replaced by revised "Commercial" and new "Transportation" columns.
    • Average Retail Prices of Electricity:
    • Beginning in 2003, the "Commercial," "Industrial" and "Other" columns previously shown in Table 8.10 are replaced by redefined "Commercial" and "Industrial" and new "Transportation" columns.

Changes in Annual Energy Review 2002

  • Annual Energy Review 2002 Release: October 24, 2003

    • Table 1.3, "Energy Consumption by Source, 1949-2002" and Table 2.1f "Electric Power Sector Energy Consumption, 1949-2002" have been modified by combining electricity net imports derived from fossil fuels and renewable sources into one category with their sources unspecified. EIA previously estimated the proportions of traded electricity from fossil fuels and hydropower (and applied the fossil-fuel steam-electric-plant heat rate to convert from kilowatthours to Btu) and from geothermal (and applied the heat rate for geothermal energy plants). EIA no longer has adequate data to estimate the proportions by source and is now applying an overall rate of 3,412 Btu per kilowatthour to all traded electricity.
    • See Note 1 at the end of Section 1.
    • Table 1.5, "Energy Consumption, Expenditures, and Emissions Indicators, 1949- 2002" has been modified by the addition of emissions indicators.
    • Table 10.2b "Renewable Energy Consumption: Electric Power Sector and Total, 1949-2002" has been modified by taking electricity net imports that are derived from hydroelectric power and geothermal energy out of the renewable energy consumption total. Those quantities continue to be included in total U.S. energy consumption as components of electricity net imports, with fuel sources unspecified. The change results in a 0.0-to-0.5 quadrillion Btu drop in total renewable energy consumption from 1949 forward.
    • These tables have been added this year:
    • Table 8.3a, "Consumption of Combustible Fuels for Electricity Generation and Useful Thermal Output at Electricity-Only and Combined-Heat-and-Power Plants: Total (All Sectors), 1989-2002."
    • Table 12.7, "Emissions From Energy Consumption for Electricity and Useful Thermal Output at Electricity-Only and Combined-Heat-and-Power Plants, 1989-2001."
  • These AER 2001 tables are reordered in the AER 2002:

  • Changes to the AER

    • Tables with grayed-out numbers go to the MER (the most recent data). The remaining tables still go to the AER 2011 (data through 2011). In some cases the table numbering of the AER differs from that of the MER.

    • Explanatory notes for the most recent AER can be found in archived AER 2011 (data year dropdown above). MER notes and sources are linked at the bottom of the interactive tables.
