Cost-effectiveness evaluations compare energy efficiency's benefits and costs to judge whether to expand, retain, revise, or eliminate efficiency programs or specific measures. This presentation discusses the basics of cost-effectiveness assessments for utility customer-funded efficiency portfolios as well as issues and options that should be considered when assessing cost-effectiveness, selecting which test(s) to use, and quantifying the components of tests (e.g., non-energy impacts, measure costs).

The catalog is a compilation of state and local energy efficiency potential studies to serve as a resource for energy planners and as a baseline for future analyses.

This paper is a baseline assessment of electric and natural gas energy efficiency programs that target low-income households in the largest metropolitan areas in the country. ACEEE surveyed over 70 electric and natural gas utilities on their 2015 low-income program spending, energy savings, customer participation, and best practices.

This report is a guide to all customer-facing financing products—products offered by a lender directly to a borrower—used to pay for energy efficiency. Intended for state and local governments that are deciding whether to start a new program, tune up and existing program, or create a Green Bank, it provides information on the full range of financing product options for target participants, the tradeoffs of various products, and potential advantages and disadvantages for different types of customers.

This Guide is designed to help state and local policymakers to take full advantage of new policy developments by providing them with a comprehensive set of tools to support launching or accelerating residential energy efficiency programs. The Guide focuses on four categories of policies that have proven particularly effective in providing a framework within which residential energy efficiency programs can thrive: incentives and financing, making the value of energy efficiency visible in the real estate market, data access and standardization, and supporting utility system procurement of energy efficiency.

This presentation covers lesson learned for PACE from the Toledo Port Authority, innovative real estate finance solutions from the Ygrene Energy Fund, and financing energy improvements on utility bills.
