U.S. Standard Industrial Classification ( SIC) codes and Canadian North American Industrial Classification ( NAIC) codes are systems of numerical codes that categorize industrial facilities by the type of activity in which they are engaged. For example, SIC code 2911 refers to petroleum refineries and NAIC code 1111 represents the soft drink industry. Each code number represents an industrial sector.
An energy-consuming sector that consists of all facilities and equipment used for producing, processing, or assembling goods. The industrial sector encompasses the following types of activity: manufacturing (NAICS codes 31-33); agriculture, forestry, and fisheries (NAICS code 11); mining, including oil and gas extraction (NAICS code 21); natural gas transmission (NAICS code 2212); and construction (NAICS code 23). Overall energy use in this sector is largely for process heat and cooling and powering machinery, with lesser amounts used for facility heating, air conditioning, and lighting. Fossil fuels are also used as raw material inputs to manufactured products. Note: This sector includes generators that produce electricity and/or useful thermal output primarily to support the above-mentioned industrial activities.
