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 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 case study presents information about the AlabamaWISE program. It includes background information, approaches the program took to enhance home energy efficiency, and results achieved by the program.

This resource provides best practices and highlights case studies for how utilities, policymakers, building managers, and community stakeholders can improve access to energy usage data while working towards the goal of improving efficiency in their communities.

There are more than 17 million multifamily households nationwide, yet they remain a significant and mostly untapped opportunity for energy efficiency gains. Many cities and states that have embraced energy retrofitting as a job creator and boon to both the environment and economy have yet to address potential savings in multifamily properties, primarily because of obstacles not faced by single family and commercial properties. This paper discusses two barriers -- a lack of information and financing -- that stand in the way of multifamily energy retrofits.

This report provides an overview of the current state of on-bill programs and provides actionable insights on key program design considerations for on-bill lending programs.

This report summarizes ongoing and recent policy developments that support utility investments in energy efficiency, including program cost recovery, fixed cost recovery, and performance incentives for electric utilities on a state-by-state basis.

This report describes different approaches to energy efficiency finance taken by utilities.

This report identifies issues associated with developing a national evaluation, measurement, and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities.

This report helps policymakers understand how electric and natural gas utilities can achieve greater efficiency by establishing numeric energy savings targets and goals for energy efficiency programs.

This report provides an overview of evaluation, measurement, and verification approaches used to estimate the load impacts and effectiveness of energy efficiency programs.

This brief focuses on loan programs in 30 states that are currently providing low- to no-interest loans to finance energy efficiency improvements--from energy-efficient windows to replacement HVAC systems--in the residential, business, and public sectors.

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.
