To account for changes in electricity generation efficiency an alternative concept of source energy is computed, one that effectively holds the energy intensity in the electric utility sector (ratio of losses to sales to end users) constant (see methodology in the comprehensive 2014 report – Section 2.6). An issue with the use of source energy is that both improvements in energy efficiency in the consuming sector, as well as improvements in the generation of electricity can affect the trend in energy intensity. Source energy, adjusted for electricity generation efficiency changes. The sum of source energy for four end-use sectors (transportation, industrial, residential buildings, and commercial buildings) is equal to the economywide use of energy defined in the system of indicators. These losses are allocated to the end-use sectors in proportion to their direct electricity consumption.
INTENSITY MEANING PLUS
Source energy consumption is defined as delivered energy plus the energy losses associated with the production of electricity by the utility sector (i.e., losses that occur in the generation, transmission, and distribution). Delivered energy is sometimes referred to as "site" energy. As such, it is the sum of fossil and renewable fuels (e.g., biomass or fuel wood) and purchased electricity. These definitions are discussed below.ĭelivered energy is the amount of energy consumed at the point of sale (e.g., that enters the home, building, or establishment) without adjustment for any energy loss in the generation, transmission, and distribution of that energy. Three separate definitions of energy are used in the system of indicators: 1) delivered, 2) source, and 3) source, adjusted for electricity generation efficiency change. The terms related to various definitions of energy are discussed first.
