1<br />

Anthracite, bituminous, subbituminous, lignite, waste coal, and coal synfuel.<br />

2<br />

Distillate fuel oil, residual fuel oil, jet fuel, kerosene, and waste oil.<br />

3<br />

Blast furnace gas, propane gas, and other manufactured and waste gases derived from fossil fuels.<br />

4<br />

Wood, black liquor, other wood waste, biogenic municipal solid waste, landfill gas, sludge waste, agriculture byproducts, other biomass, geothermal, solar thermal,<br />

photovoltaic energy, and wind.<br />

5<br />

Non-biogenic municipal solid waste, batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, tire-derived fuel, and miscellaneous technologies.<br />

* = Value is less than half of the smallest unit of measure (e.g., for values with no decimals, the smallest unit is "1" then values under 0.5 are shown as "*".)<br />

Notes: • Beginning with 2001 data, non-biogenic municipal solid waste and tire-derived fuels are reclassified as non-renewable energy sources and included in "Other".<br />

Biogenic municipal solid waste is included in "Other Renewables." • Beginning with the collection of Form <strong>EIA</strong>-923 in January 2008, the methodology to allocate total fuel<br />

consumption for electricity generation and consumption for useful thermal output was changed. The new methodology was retroactively applied to 2004-2007. See the<br />

Technical Notes (Appendix C) for further information. • See Glossary for definitions. • Values for 2010 and prior years are final. Values for 2011 are preliminary. See<br />

Technical Notes for a discussion of the sample design for the Form <strong>EIA</strong>-923 and predecessor forms. • Totals may not equal sum of components because of independent<br />

rounding.<br />
