This study estimated energy, environmental, and consumer impacts of US federal residential energy efficiency standards taking effect in the 1988-2007 period. These standards have been the subject of in-depth analyses conducted as part of the US Department of Energy's (DOE's) standards rulemaking process. This study drew on those analyses, but updated key data and developed a qommon framework and assumptions for all of the products. We estimate that the considered standards will reduce residential primary energy consumption and carbon dioxide (CO_2) emissions by 8-9% in 2020 compared to the levels expected without any standards. The standards will save a cumulative total of 26-32 EJ (25-30 quads) by the year 2015, and 63 EJ (60 quads) by 2030. The estimated cumulative net present value of consumer benefit amounts to nearly US$80 billion by 2015, and grows to US$130 billion by 2030. The overall benefit/cost ratio of cumulative consumer impacts in the 1987-2050 period is 2.75:1. The cumulative cost of the DOE's program to establish and implement the standards is in the range of US$200-US$250 million. Published by Elsevier Science Ltd.
