This case study highlights the low-income programs of Efficiency Vermont, the nation’s first public energy efficiency utility, which aims to reduce these customers' high energy burden, freeing up money that they can spend on food, housing, and other necessities. These low-income programs have saved enough electricity to power nearly 8,000 Vermont households for a year and offer solutions that eliminate or reduce up-front costs for residents, a typical barrier to improving energy efficiency in low-income households. Its multifamily energy efficiency program helps renters and building owners save energy, addressing the “split incentive” barrier in which owners have little reason to invest in efficiency measures that benefit tenants who pay their own energy bills.
This report provides an annual savings claim summary and includes case studies and customer testimonials from homeowners, towns, and businesses that Efficiency Vermont served in 2016.
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.

The report also offers an analysis of the number, spending, offerings, and targeted participants of current programs and their potential for further expansion.
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.

We report on loan performance, energy savings, and the degree to which the savings offset the cost of the energy efficiency investment.
Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

A number of states are beginning to recognize Demand Reduction Induced Price Effects (DRIPE) as a real, quantifiable benefit of energy efficiency and demand response programs. DRIPE is a measurement of the value of demand reductions in terms of the decrease in wholesale energy prices, resulting in lower total expenditures on electricity or natural gas across a given grid. This paper reviews the existing knowledge and experience from select U.S. states regarding DRIPE (including New York and Ohio), and the potential for expanded application of the concept of DRIPE by regulators.
This study documents the market valuation associated with the predominant green and energy efficiency home certifications used in the Northwest. Regional markets with a track record of including green building and energy efficiency information in MLS databases have lacked a recent, thorough, locally relevant analysis of the potential value of “higher performing” homes in current market conditions. Real property appraisers require a reliable, localized, granular analysis they can use in their home valuation calculations. The analysis contained in this report addresses this identified market need.
Among the many benefits ascribed to energy efficiency is the fact that it can help create jobs. Although this is often used to motivate investments in efficiency programs, verifying job creation benefits is more complicated than it might seem at first. This paper identifies some of the issues that contribute to a lack of consistency in attempts to verify efficiency-related job creation. It then proposes an analytically rigorous and tractable framework for program evaluators to use in future assessments.
This report was prepared to provide an overview and analysis of results and lessons learned under Efficiency Vermont’s program from 2011-2013.

Many states have adopted policies intended to overcome the barriers that limit the more efficient use of electricity. Yet because such efforts have not addressed the lack of consumer information and motivation to improve efficiency, many opportunities for energy efficiency remain untapped. To help address that problem, states, utilities, and other energy efficiency service providers have begun to develop new approaches to informing and motivating customers based on behavioral economics and psychology research. This report describes three broad strategies that states can use to engage consumers' participation in energy efficiency programs: provide direct consumer information and feedback on energy use, influence social norms; and match messages and messengers to target audiences. Recommendations for actions that governors can take within the context of each of those three strategies are provided.
