What's New in Annual Energy Review 2007

Noteworthy changes include:

Table 1.13, U.S. Government Energy Consumption by Agency and Source: Reconfigured to cover three years of data---2003, 2006, and 2007.

Table 4.1, Technically Recoverable Crude Oil, Natural Gas, and Natural Gas Liquids Resource Estimates: Data broken out by “Federal Lands” and “Non-Federal Lands” are no longer available for this table.

Table 10.3, Fuel Ethanol and Biodiesel Overview: Biodiesel 2001-2005 data in British thermal units (Btu) are revised because of the application of gross heat content (higher heating value) in place of net heat content (lower heating value); 2006 and 2007 biodiesel data are added; and fuel ethanol production and biodiesel production now include data displayed in million gallons as well as thousand barrels and trillion Btu.

Table A3, Approximate Heat Content of Petroleum Consumption and Biofuels Production: Approximate Heat Content of Petroleum Consumption and Biofuels Production.

Table D1, Population, U.S. Gross Domestic Product, and Implicit Price Deflator: U.S. population data in decennial years (i.e., years ending in 0) are revised from April 1^st counts to July 1^st counts so that all population data are now July 1^st counts. The change affects per person data in Table 1.5, Energy Consumption, Expenditures, and Emissions Indicators.

What's New in Annual Energy Review 2006

The following AER 2005 table is deleted in AER 2006: Table 2.11, “Commercial Buildings Electricity Consumption by End Use, 1999.”

The following table is new in AER 2006: Table 10.3, “Ethanol and Biodiesel Overview, 1981-2006.”

The following AER 2005 tables are renumbered in the AER 2006:

Other changes in this year’s report include:

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

Table 2.1d and 2.1e: Beginning in 1993, “Petroleum” is revised to exclude the ethanol portion of motor gasoline. Ethanol is included in “Biomass.”

Table 7.4: 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,” at:http://www.eia.doe.gov/cneaf/solar.renewables/page/mswaste/msw.pdf.

Table 8.11a-d: “Dual-fired” column is deleted. The data are assigned to appropriate primary fuel categories.

Table 9.1: Redesigned to categorize nuclear generating units by Nuclear Regulatory Commission regulation 10 CRF Part 50 and regulation 10 CFR Part 52.

Table A3: Approximate heat content data for “Fuel Ethanol,” Ethanol Feedstock,” “Biodiesel,” and “Biodiesel Feedstock” are added.

Table A5: Approximate heat content data for “Waste Coal Supplied” are added.

What's New in Annual Energy Review 2005

Noteworthy changes include:

Table 1.14: Data for 2001 forward are switched from calendar year to fiscal year.

Table 6.6: A column for natural gas underground storage capacity is added.

Table 10.2a: Residential wood data from 1980 forward and commercial wood data from 1989 forward are revised.

Section 11: “Western Europe” and “Eastern Europe and Former U.S.S.R.” are replaced with the new groupings “Europe” and “Eurasia.”

What's New in Annual Energy Review 2004

Noteworthy changes include:

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.

The following tables are new in the AER 2004:

What's New in Annual Energy Review 2002

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:
