Report describing a goal of achieving all cost-effective energy efficiency by 2025; presents ten implementation goals for states, utilities, and other stakeholders to consider to achieve this goal, and describes what 2025 might look like if the goal is achieved.

This report discusses the five standard tests used to assess the cost-effectiveness of energy efficiency, how states use the tests, and how the tests can determine the cost-effectiveness of efficiency measures.

This report describes the effects of utility spending on efficiency programs, how those effects could constitute barriers to investment in energy efficiency, and how policy mechanisms can reduce these barriers.

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 report provides guidance on determining the efficiency potential in a utility footprint, state, or region; evaluating efficiency as a supply-side resource; and developing detailed efficiency program plans.

This report describes the key issues, best practices, and main process steps for integrating energy efficiency into resource planning on an equal basis with other resources.

This guide describes a structure and several model approaches for calculating energy, demand, and emissions savings resulting from energy efficiency programs that are implemented by cities, states, utilities, companies, and similar entities.

Research traditions across the social sciences have explored the drivers of individual behavior change and proposed different models of decision making. In this paper, four diverse perspectives are reviewed: conventional and behavioral economics, technology adoption theory and attitude-based decision making, social and environmental psychology, and sociology. This paper concludes with how to develop a more integrated approach to both behavioral change research and intervention design in a residential energy context.

The purpose of this study is to furnish comprehensive information on ratepayer-funded low-income energy programs. This study includes information on and analysis of the energy needs of low-income households, the legal and regulatory framework supporting ratepayer-funded programs, program design options, and the findings from evaluations of program effectiveness.
