本报告介绍了美国能源部能源效率和可再生能源办公室（EERE）在过去十年中开发的能源强度指标综合系统。这一指标体系是分层次的，首先是经济各部门的能源密集度详细指数，最后汇总为整个经济的总能源密集度指数。将能源强度指数汇总到层次结构中的较高级别是使用对数平均Divisia指数（LMDI）方法的一个版本进行的。根据指标体系中的数据和方法，整个经济的能源强度指数显示，2010年相对于1985年基准年下降了约14%。报告中讨论了经济中每一个广泛的最终用途部门--住宅、商业、工业和运输--的能源强度指标。还包括对美国发电效率最近变化的分析。详细的附录介绍了每个部门能源密集度指标背后的数据来源和方法。
This report describes a comprehensive system of energy intensity indicators for the United States that has been developed for the Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) over the past decade. This system of indicators is hierarchical in nature, beginning with detailed indexes of energy intensity for various sectors of the economy, which are ultimately aggregated to an overall energy intensity index for the economy as a whole. The aggregation of energy intensity indexes to higher levels in the hierarchy is performed with a version of the Log Mean Divisia Index (LMDI) method. Based upon the data and methods in the system of indicators, the economy-wide energy intensity index shows a decline of about 14% in 2010 relative to a 1985 base year. Discussion of energy intensity indicators for each of the broad end-use sectors of the economy—residential, commercial, industrial, and transportation—is presented in the report. An analysis of recent changes in the efficiency of electricity generation in the U.S. is also included. A detailed appendix describes the data sources and methodology behind the energy intensity indicators for each sector.
