Overview Energy Efficiency Programs
Infographics Highlight Benefits Provided by State Energy Efficiency Programs Over the 2012-2023 Time Period
Each state in New England operates and administers state energy efficiency programs that leverage surcharges on customer electricity and natural gas bills, combined with other funding sources, to deliver energy efficiency and electrification improvements to customers, from households and businesses to municipalities. While these programs have been operating for different lengths of time depending on the state, most programs in New England commenced operation in the late 1990s or early 2000s. Based on data made available by each of the state-level programs, the below infographics succinctly summarize the benefits energy efficiency programs have delivered over the 2012-2023 time period, both at an individual state level and more broadly at an aggregated regional level.
As the first infographic below highlights, collectively since 2012, these programs have delivered over $55 billion in total lifetime benefits to households and businesses across the region, providing over $3.40 in benefits per every $1.00 invested in the programs. Simultaneously, the programs play an instrumental role in creating and sustaining over 160,000 energy efficiency industry jobs in the region and have reduced lifetime CO2 emissions at levels equivalent to removing nearly 33 million gasoline-powered cars from the road for one year. Additionally, the programs have generated significant health benefits associated with a reduction in fossil fuel combustion, improved occupancy comfort, and reduced stress on and improved reliability of the regional electric grid.

The regional infographic above and state infographics below not only highlight the progress made to date but also serve to highlight the critical role that energy efficiency and electrification programs will need to play in the coming decades to achieve the climate goals of the region while simultaneously delivering cost savings to consumers and improving overall quality of life in the region. Acadia Center is proud to have been a key advocate and catalyst over the past decade for the policies that have boosted energy efficiency. Acadia Center firmly believes that the progress described below, while substantial, represents only a fraction of the full technical and economic potential for energy efficiency in the region, especially when considering its potential as a competitive resource to provide services to and reduce costs for the region’s electricity grid.
The data presented in the infographics is based on data provided by individual state energy efficiency programs. The specific methodologies used to calculate lifetime energy savings, greenhouse gas (GHG) emissions avoided, program costs, and program benefits vary across states and can sometimes make cross-state comparisons challenging at times. Acadia Center presents the data based on what was provided by state agencies with no modifications or edits to state-specific methodologies.
