| [10] Retail sales and net generation may not correspond exactly for a particular month for a variety of reasons (e.g., sales data may include imported electricity). Net generation is for the calendar month while retail sales and associated revenue accumulate from bills collected for periods of time (28 to 35 days) that vary dependent upon customer class and consumption occurring in and outside the calendar month. | |||||||||||
| [11] See Technical notes for additional information on the Commercial, Industrial, and Transportation sectors. | |||||||||||
| * = 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 “*”.) | |||||||||||
| Notes: • Beginning with the collection of Form EIA-923 in January 2008, the methodology to allocate total fuel consumption for electricity generation and consumption for useful thermal output was changed. The new methodology was retroactively applied to 2004-2007. See the Technical Notes (Appendix C) for further information. • Beginning with 2001 data, non-biogenic municipal solid waste and tire-derived fuels are reclassified as non-renewable energy sources and included in “Other”. Biogenic municipal solid waste is included in “Other Renewables.” • Values for 2010 are final. Values for 2011 are preliminary and are estimates based on samples. See Technical Notes for a discussion of the sample designs. • Totals may not equal sum of components because of independent rounding. • Percentage difference is calculated before rounding. • Monetary values are expressed in nominal terms. | |||||||||||
