Total Energy
Total Energy Flow, 2010 (Quadrillion Btu)
Footnotes:
1 Includes lease condensate.
2 Natural gas plant liquids.
3 Conventional hydroelectric power, biomass, geothermal, solar/photovoltaic, and wind.
4 Crude oil and petroleum products. Includes imports into the Strategic Petroleum Reserve.
5 Natural gas, coal, coal coke, biofuels, and electricity.
6 Adjustments, losses, and unaccounted for.
7 Coal, natural gas, coal coke, electricity, and biofuels.
8 Natural gas only; excludes supplemental gaseous fuels.
9 Petroleum products, including natural gas plant liquids, and crude oil burned as fuel.
10 Includes 0.01 quadrillion Btu of coal coke net exports.
11 Includes 0.09 quadrillion Btu of electricity net imports.
12 Total energy consumption, which is the sum of primary energy consumption, electricity retail
sales, and electrical system energy losses. Losses are allocated to the end-use sectors in
proportion to each sector’s share of total electricity retail sales. See Note, “Electrical Systems
Energy Losses,” at end of Section 2.
Notes:
• Data are preliminary.
• Values are derived from source data prior to rounding for publication.
• Totals may not equal sum of components due to independent rounding.

Energy Perspectives
Forty-three interactive graphs showing trends in U.S. energy production, consumption, and trade from 1949-2010
Changes in AER 2010:
- Energy Resources has been expanded to include six maps showing U.S. renewable energy resources.
- Appendix F has been added to include an explanation of alternatives for estimating energy consumption.
- Primary Energy Production by Source (Table 1.2), Consumption for Electricity Generation by Energy Source: Electric Power Sector (Table 8.4b), and other tables have new values for geothermal energy, due to the use of a different Btu conversion factor for geothermal electricity net generation.
- Primary Energy Consumption by Source (Table 1.3) has been reconfigured to display noncombustible renewable energy in three columns: Captured Energy, Adjustment for Fossil Fuel Equivalence, and Primary Energy Total.
