State and local governments across the U.S. are focused on how clean energy can help them meet a variety of energy, economic development, and environmental goals. An early step for most energy efficiency planning involves identifying and quantifying energy savings opportunities, followed by understanding how to access this efficiency potential.  This website includes national and state-level energy efficiency potential studies for the residential, commercial, and industrial sector.  It introduces presentations on how building energy codes, city-led efforts, energy savings performance contracting (ESPC), industrial, and ratepayer-funded efforts can support state energy planning.

Since 2012, MarylandÕs Department of Housing and Community Development (DHCD) has administered the stateÕs limited-income energy efficiency programs. The programs have been effective in delivering substantial energy savings for each participating household, but overall participation has been low. This report documents the development, successes, and challenges of DHCDÕs programs. Findings from this report rely on information collected from Maryland stakeholders, public program filings, discussions with leading energy efficiency professionals, and ACEEEÕs past best practices research. The report concludes by identifying several opportunities to improve future program performance.

This report examines the history of pay-for-performance (P4P) energy efficiency approaches. As the report describes, there is a diverse spectrum of pay-for-performance programs but, at the most basic level, these programs track and reward energy savings as they occur, usually by examining data from a building's energy meters -- as opposed to the more common approach of estimating savings in advance of installation and offering upfront rebates or incentives in a lump-sum payment. The report finds that P4P has some important opportunities for increasing energy savings, but also key limitations that will need to be better understood through piloting and experimentation.

This paper presents results from three surveys of homeowners, renters, and contractors, which compared their perceptions and priorities for healthy housing to the principles of indoor air and environmental quality. Survey results indicate that: nearly one quarter of homeowners had some concern about healthy-home problems or risks; homeowners cited indoor air quality issues as their leading concern, followed by water quality, harmful materials and chemicals, and indoor environmental quality (such as noise or light pollution).

Behavioral change programs are not necessarily a separate category of efficiency efforts; rather, behavioral approaches can be effectively integrated into all programs in residential, commercial, or industrial settings. As increased connectivity within homes and businesses expands opportunities to provide energy information, the role of behavior will likely become even more prominent. Consortium for Energy Efficiency, Inc. (CEE) provides this webpage dedicated to behavior change resources.

Several recent studies purport to show that particular energy efficiency programs and policies do not work or are too expensive. This short paper is written for people who are not evaluation experts and are trying to understand what conclusions they can take from these studies. We examine many of these papers and find that while they do have some useful findings, they often include a variety of unreasonable assumptions or outright mistakes that undermine their conclusions. Based on this review, we offer several recommendations on ways we can constructively move forward.
