Book Description
Energy use in the United States is substantially lower now than it would have been had energy intensities not fallen after the oil price shocks of the 1970s. The United States would have consumed over 30 quadrillion Btu (QBtu) more energy in 1991 if the energy-GDP ratio (energy divided by gross domestic product) had remained at its 1972 value. Much of this improvement has stemmed from developments within the industrial sector. This paper examines industrial energy use from two perspectives. First, the contribution of the industrial sector to the decline in the overall energy-GDP ratio is estimated. Second, the components of change in conservation trends within the industrial sector are examined. This part of the analysis identifies the change in overall industrial intensity (total energy consumption/total industrial output) that is due to improvements in energy intensity at the individual industry level in comparison to various aspects of the composition of industrial output. This paper is based upon recent work conducted by Pacific Northwest Laboratory for the Office of Energy Efficiency and Alternative Fuels Policy, U.S. Department of Energy. Discussion of other end-use sectors and some additional analysis of industrial sector energy trends is found in Energy Conservation Trends - Understanding the Factors Affecting Conservation Gains and their Implications for Policy Development.

Book Description
Over the past two decades energy consumption in commercial buildings has been the fastest growing segment among the major end-use sectors in the US. This paper provides a decomposition of the major factors behind the trends in commercial energy use over this period. It examines the impact on overall commercial sector energy intensity from: (1) new buildings, (2) changes in the composition of buildings by geographic region and building type, (3) the growth in office equipment and computers, and (4) the influence of several common envelope conservation measures. A statistical decomposition of historical monthly electricity and gas consumption data is developed to separate energy use into heating, cooling, and ventilation (HVAC) and other components (non-HVAC). This data is then used in conjunction with historical commercial building floor space estimates to derive end-use intensities for these components of energy consumption. Deterministic analyses are performed to estimate the impacts of other factors. The impact of new buildings is measured by estimating the average improvement in heating efficiencies for buildings built after 1980. The effect of building composition on aggregate commercial building energy intensity is based upon estimates of historical floor space by building type and region and building-specific intensities derived from the 1989 Commercial Building Energy Consumption Survey (CBECS). Stocks of various types of office equipment were constructed from industry statistics and independent surveys. The stocks of selected office equipment were combined with estimates of unit energy consumption to estimate the impact on total commercial electricity consumption. For estimating changes in energy intensity due to the building retrofits, the study utilizes a new energy simulation tool developed as part of the Facility Energy Decision Screening (FEDS) system for the US Department of Energy.

Book Description
Taken from a report for the Electric Power Research Institute, Joy Dunkerley’s study aims to clarify the relationship between energy consumption and economic output in industrialised countries. Originally published in 1980 and using data from 1972, this study uses cross-country comparisons of energy use to stress the importance of new supply options and measures of controlling energy use without affecting living standards whilst also discussing the impact of energy prices and economic growth in the countries studied. This title will be of interest to students of environmental studies.
