http://www.eia.doe.gov/emeu/sep/states.htmlThe five economic sectors:

Residential Sector The residential sector is considered to consist ofall private residences, whether occupied or vacant, owned orrented, including single- family homes, multifamily housing units,and mobile homes. Secondary homes, such as summer homes, arealso included. Institutional housing, such as school dormitories,hospitals, and military barracks, generally are not included in theresidential sector; they are included in the commercial sector.

Commercial Sector The commercial sector, as defined economi-cally, consists of business establishments that are not engaged intransportation or in manufacturing or other types of industrial ac-tivity (agriculture, mining, or construction). Commercialestablishments include hotels, motels, restaurants, wholesale busi-nesses, retail stores, laundries, and other service enterprises;religious and nonprofit organizations; health, social, and educa-tional institutions; and Federal, State, and local governments.Street lights, pumps, bridges, and public services are also includedif the establishment operating them is considered commercial.

Industrial Sector The industrial sector comprises manufacturingindustries, which make up the largest part of the sector, along withmining, construction, agriculture, fisheries, and forestry. Estab-lishments in the sector range from steel mills, to small farms, tocompanies assembling electronic components.

Transportation Sector The transportation sector consists of privateand public vehicles that move people and commodities. Includedare automobiles, trucks, buses, motorcycles, railroads and railways(including streetcars), aircraft, ships, barges, and natural gaspipelines.

Electric Utility Sector The electric utility sector consists of pri-vately and publicly owned establishments that generate,transmit, distribute, or sell electricity primarily for use by thepublic and meet the definition of an electric utility. Nonutilitypower producers are not included in the electric utility sector.Although end- use allocations of energy consumption and expendituresfollow those guidelines as closely as possible, some data are collectedby using different classifications. For example, electric utilities oftenclassify commercial and industrial users by the quantity of electricitypurchases rather than by the business activity of the purchaser. Agricul-tural use of natural gas is collected and reported in the commercialsector, rather than in the industrial sector. Since agricultural use ofnatural gas cannot be identified separately, it remains in the commercialsector in this report. Another example is master- metered condomini-ums, apartments, and buildings with a combination of residential andcommercial units. In many cases, billing and metering practices causeresidential energy usage of electricity, natural gas, or fuel oil to be in-cluded in the commercial sector. In those cases, there is no basis forseparating residential from commercial use. Readers are advised to con-sult the SEDR documentation for specific assumptions regarding theconsumption estimates.

Where prices for an energy source and sector are not available, compa-rable prices are substituted. For example, the transportation sectormotor gasoline prices are also applied to the commercial and industrialsectors. In some cases, the average of adjacent States prices is assignedto a missing State price. The documentation elaborates on these priceassumptions.

Except where specified, it is not generally possible to describe the pricesin this report as wholesale or retail. The prices paid in each con-suming sector are actually a combination of both sets of prices,depending on a number of closely interrelated factors, and the data re-flect the combination of prices actually paid by each sector. Almost allresidential sector prices are close to retail prices, reflecting the relativelysmall quantities of individual purchases and the increased costs ofextensive, diffuse, and multilayered distribution systems. Similarly, in thetransportation sector almost everyone pays the same retail- like price formotor gasoline, regardless of volume purchased or location of purchase.

Conversely, residual fuel oil prices in the transportation sector are certainlymore wholesale- like as a result of large deliveries to bulk facilities in majorports. In the same manner, most large industrial and many large commer-cial expenditures can be thought of as near wholesale, frequently involvingdirect access to a producer or bulk distribution facility for very largequantities. Many smaller industrial and commercial facilities pay some-thing much closer to retail prices as a result of the small quantitiesinvolved and their institutional distance from primary suppliers. Nota-ble exceptions to these relationships include natural gas and electricutilities, which typically establish fixed rates for each of several classesof service, depending on representative quantities, service factors, anddistribution expenses.
