This study provides an overview of practices for quantifying and reporting avoided energy-water costs from demand-side measures. It also summarizes the regulatory guidance for incorporating water savings into cost-effectiveness screening for energy efficiency programs.

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 report details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.

This report summarizes the scale and economic value of energy efficiency for reducing carbon emissions and discusses barriers to achieving the potential for cost-effective energy efficiency.
