Energy efficiency savings have grown substantially in the past ten years, and national leaders in program administration have emerged as savings levels have increased. This report reviews annual program performance for 14 leading energy efficiency program administrators, with a focus on costs, electricity savings, cost effectiveness, and portfolio design.

This study focused on homeowner decision-making in response to home energy assessments, combined with the quality of the recommendations, the home energy assessment, and home energy labels. This report analyzes what assessments provide and what homeowners seem to want. It presents the results of a study of an existing home energy audit program pilot offered by Seattle City Light. From mid-2010 to late 2011, approximately 1,350 home energy assessments were completed in Seattle as part of Seattle City Light's program.

This paper describes a wide variety of behavior change insights potentially applicable to the energy efficiency program context, provides examples of efficiency programs that have applied these insights, and explores some untapped opportunities to achieve energy savings through behavior change.

This guide provides background on the home improvement market in the U.S. and Canada and end users and systems in existing homes, as well as a description of energy efficiency program approaches and strategies.
