This document constitutes the final report for the 2009-2010 process evaluation of the Low Income Energy Efficiency (LIEE) program operated by the four investor-owned utilities (IOU) of California for the California Public Utilities Commission (CPUC). The IOUs include: Pacific Gas and Electric Company (PG&E), Southern California Edison (SCE), Southern California Gas (SCG), and San Diego Gas and Electric (SDG&E). Although the program is now referred to as Energy Savings Assistance Program (ESAP), this report will employ the nomenclature used for the 2009-2010 program cycle.

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.

This report presents the findings of Phase 2 of the California Public Utilities Commission Low Income Needs Assessment Study. The results of the needs assessment suggest that, over time, the programs have effectively targeted and provided services to low-income households that have the greatest need.

This paper presents the results of a comprehensive study of the energy-related needs of California’s low-income population. This study was commissioned to direct future policy regarding the various low-income energy programs offered in the state. These programs include the California Alternate Rate for Energy (CARE) Program, which provides a rate discount to qualified low-income customers, and the Low-Income Energy Efficiency (LIEE) Program, which installs weatherization and energy efficiency measures in qualified dwellings at no charge.
