“…From the early-1980s to the present, electricity consumption (and electricity's share of final energy consumption) in industry has remained flat or declined. Reasons for this include within-sector structural changes, technology transitions, fuel supply and price considerations, and energy intensity improvements (Croner and Frankovic 2018;Belzer 2014;Boyd and Roop 2004). 17…”

“…17 Trends in the electricity intensity of manufacturing have been found to be markedly different from trends in fuel use since 1970. Using a Divisia index decomposition, Belzer (2014) estimated that from 1970 to 1985 manufacturing electricity intensity remained relatively constant while fuel intensity decreased by more than 30%. The most recent decomposition analysis of electricity use by U.S. manufacturers estimated that the reduction in electricity intensity during the 1990s was due in equal parts to structural change and improvements in intensity (Boyd and Roop 2004).…”

“…These trends are most evidently observed in the right graph in Figure 2.4, where all tracesincluding population, energy and electricity consumption, and emissions-have negative slopes after 1980, indicating they decrease relative to GDP. The continued GDP growth despite decreasing energy consumption indicates an increasingly energy efficient economy (Belzer 2014;Huntington 2010). The electricity consumption trends per dollar of GDP show an interesting inflection around 1980, where the slope changes sign from positive to negative, demonstrating the reduced correlation between economic growth and electricity consumption.…”

This report is one in a series of Electrification Futures Study (EFS) publications. The EFS is a multi-year research project to explore potential widespread electrification in the future energy system of the United States. Electrification is defined as the substitution of electricity for direct combustion of non-electricity-based fuels (e.g., gasoline and natural gas) used to provide similar services.The EFS is specifically designed to examine electric technology advancement and adoption for end uses in all major economic sectors as well as electricity consumption growth and load profiles, future power system infrastructure development and operations, and the economic and environmental implications of electrification. Because of the expansive scope and the multi-year duration of the study, research findings and supporting data will be published as a series of reports, with each report released on its own timeframe. The table below shows the various research topics planned for examination under the EFS and how this report fits with the other components of the study. Topic Relation to this Report Electric technology cost and performance projections Provides technology data used in this report (Jadun et al. 2017) Electrification demand-side adoption scenarios This report Electric system supply-side scenarios Relies on electricity consumption reported in this report Electricity consumption patterns Relies on technology adoption projections reported in this report Electric system operations Relies on the consumption patterns and supplyside scenarios from other reports, which rely on data from this report Impacts assessment Relies on the technology adoption projections in this report along with data from other reportsThis report is the second publication in this series and presents scenarios of electric end-use technology adoption and resulting electricity consumption in the United States. The scenarios reflect a wide range of electricity demand growth through 2050 that result from various electric technology adoption and efficiency projections in the transportation, residential and commercial buildings, and industrial sectors. The report describes the methodology, assumptions, and limitations of the analysis. The demand scenarios provided in this report will be used to inform the supply scenarios and impacts to be presented in future reports under the EFS project. Results from the current demand-side scenarios can also be used by other researchers who wish to explore implications of electrification and demand growth in the U.S. economy.More information, the supporting data associated with this report, links to other reports in the EFS study, and information about the broader study are available at www.nrel.gov/efs. vi

“…Under given conditions, SDA and IDA are consistent [9] and can be derived and transformed from each other [10]. The energy intensity changes in different countries from different years have been analyzed by related empirical studies, such as the United States in 1985-2010 [11], Australia in 1978-2009 [12], and Canada in 1990-2004 [13]. Since the reform and opening up, a 70% reduction of China's energy intensity exceeded the global average level of 36%, which has drawn worldwide attention from the academic communities.…”

Improving the world's aggregate energy efficiency is consequential for global sustainable development. This paper evaluated the world's aggregate energy intensity reduction along with economic growth and industrial transformationusing the panel data of all countries around the world from 1971 to 2016. The overall energy intensity of the world was decomposed into activity mix and national intensity based on LMDI approach, and we found that the latter was the main driving force for the reduction of the world's overall energy intensity. We further analyzed the relationship between energy prices, technological progress, and national intensity. The results showed that technological progress and energy prices significantly decreased national intensity, with significant regional differences, however, no significant impact appeared in a price-declining period. To reduce energy intensity, localized measures in different supra-national regions are needed.

We develop and illustrate a method for reconciling index decomposition analysis of energy intensity with physically based, sector-specific energy efficiency indicators. Decomposition analysis of individual sector intensity contributions to total energy intensity is nested within the higher-order decomposition analysis of E/GDP such that the contribution of energy efficiency gains to changes in total energy intensity can be determined. Energy, economic and physical activity data for Canada for the period 1995-2010 are used to illustrate the method. Intrasector structural factors were found to be both positive and negative and to be significant contributors to energy intensities in both the business and household sectors. In aggregate, intrasectoral structural change offset energy efficiency gains and put upward pressure on (E/GDP) between 1995 and 2010 but was three times smaller than the offsetting decline in E/GDP due to intersectoral structural change. The method can be used for assessing the contribution of energy efficiency to sector energy intensities; for placing energy efficiency policies in the larger context of the other factors that determine an economy's energy intensity and greenhouse gas emissions; for identifying nonefficiency policy targets for improving energy productivity; and for increasing the sophistication of forecasting and scenario analysis of future levels and patterns of fuel and electricity consumption and related greenhouse gas emissions.
