Primary Energy Consumption by Source (Table 1.3):
 — Reconfigured to display noncombustible renewable energy (hydroelectric power, geothermal, solar thermal and photovoltaic, and wind) broken into three columns:
 — Captured Energy
 — Adjustment for Fossil-Fuel-Equivalence
 — Primary Energy Total

See Note 1 at the end of Section 1 and Appendix F for more information.

Heat Content of Petroleum Products Supplied (Table 5.12):
 — Liquefied Petroleum Gases (LPG), Other Petroleum Products, and Total Petroleum estimates for all years revised due to new estimation methodologies.

Consumption for Electricity Generation by Energy Source: Electric Power Sector (Table 8.4b):
 — Modified to use the fossil-fuels heat rate as the conversion factor for geothermal electricity net generation. This change affects data series in Primary Energy Overview (Table 1.1), Primary Energy Production by Source (Table 1.2), Primary Energy Consumption by Source (Table 1.3), Electric Power Sector Energy Consumption (Table 2.1f), Consumption for Electricity Generation by Energy Source: Total (All Sectors) (Table 8.4a), Renewable Energy Production and Consumption by Source (Table 10.1), and Renewable Energy Consumption: Electric Power Sector (Table 10.2c).

 — Beginning in 2001, "Biomass" is revised to remove non-renewable waste (municipal solid waste from non-biogenic sources, and tire-derived fuels). Because this portion is mostly derived from fossil fuels, which are already accounted for, it is also removed from total energy to eliminate the previous double counting.

 — From 2001-2005, "Biomass" is revised to include biodiesel and losses and co-products from the production of biodiesel.

Table 2.1c-2.1f:
 — Beginning in 1980, "Natural Gas" is revised to remove "Supplemental Gaseous Fuels."

 — U.S. coal exports to Turkey are removed from "Other" and shown in a separate column.

Table 8.2a-8.2d; 8.3a-8.3c; 8.4a-8.4c; 8.5a-8.5d; 8.6a-8.6c; and 8.7a-8.7c:
 — Beginning in 2001, "Waste" is revised to remove non-renewable waste (municipal solid waste from non-biogenic sources, and tire-derived fuels). The removed quantity is added to "Other." See article, "Methodology for Allocating Municipal Solid Waste to Biogenic and Non-Biogenic Energy,".

 — "Industrial Sector" data are moved from Table 10.2a to Table 10.2b; "Ethanol" and "Biomass Losses and Co-products" are added to "Industrial Sector."
 — "Electric Power Sector" data are moved from Table 10.2b to new Table 10.2c.

 — "Alcohol Fuels" is renamed "Ethanol"; and "Biodiesel" is added to "Transportation Sector" in Table 10.2b.
 — Beginning in 2001, "Waste" is revised to remove non-renewable waste (municipal solid waste from non-biogenic sources, and tire-derived fuels). See article, "Methodology for Allocating Municipal Solid Waste to Biogenic and Non-Biogenic Energy,".

 — "Western Europe" and "Eastern Europe and Former U.S.S.R." are replaced with the new groupings "Europe" and "Eurasia."

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.

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."
