Across Massachusetts, cities and towns are leading the way to a future powered entirely by clean and renewable sources of energy. Municipal officials and staff — working with citizen activists, volunteers, nonprofit organizations, and businesses — are taking action to reduce fossil fuel consumption and increase the use of renewable energy.
This is the fourth edition of Renewable Communities, previously published in 2016, 2019, and 2020. This year’s report includes seven new case studies of cities, towns, and regional agencies that have adopted innovative programs to promote renewable electricity, energy storage, clean heating, and energy efficiency.
While not an exhaustive survey of municipal clean energy action, these case studies illustrate ways in which action at the local level can accelerate Massachusetts’ progress toward 100 percent renewable energy. We hope this report will inspire more communities to follow the example of the cities and towns featured here.
Case studies from Renewable Communities 2021
- Arlington and Winchester: A community outreach campaign resulted in 224 contracts signed for the installation of clean heating systems like air source heat pumps.
- Chelsea: A proposed microgrid, managed by an innovative cloud-based system, would ensure clean, reliable power for buildings that provide key services to the community.
- CVEC (Cape and Vineyard Electric Cooperative): A coordinated approach to renewable energy deployment, bringing together dozens of municipalities and government agencies, has led to more than 50 megawatts of solar capacity built or in development.
- Mendon and Upton: A Solarize Mass Plus program offered residents a choice of six different clean energy technologies, including solar, battery storage, and air source heat pumps.
- Natick: Town officials have pursued several strategies to increase the deployment of solar on municipal buildings and on homes.
- Springfield: A 4.7-megawatt community solar array, built on a former landfill, is providing affordable electricity to hundreds of low-income residents.
- Worcester: The city’s Community Choice Aggregation Program is providing residents with a higher percentage of renewable electricity from sources in New England.

- Somerville: The Winter Hill in Motion initiative has improved travel along Broadway, one of the city’s busiest streets, with dedicated bus lanes.
Case studies from the 2019 edition of Renewable Communities
- Amherst: The Net Zero Buildings Bylaw requires new and renovated municipal buildings to be powered and heated entirely with renewable energy.
- Boston: The Carbon Free Boston report identifies pathways to reach the city’s goal of carbon neutrality by 2050.

- Concord, Amherst, and Cambridge: A pilot program demonstrated the viability of electric school buses to transport students to and from school without harmful emissions.
- Everett and Arlington: Bus-only lanes on major roads have decreased travel time and delays for transit riders, encouraging residents to commute by bus instead of driving.
- Gosnold: A solar microgrid, one of the first community-scale microgrids in the United States, is providing more than 50% of the electricity used on the island of Cuttyhunk during the peak summer season.
- Lexington: Two new school buildings will be powered entirely with solar panels and heated with air source heat pumps and a geothermal system.
- Lincoln, Sudbury, and Wayland: During a Solarize Mass Plus campaign, dozens of residents installed solar photovoltaic and solar hot water systems to provide their homes with renewable electricity and heating.
- Martha’s Vineyard Transit Authority: The Martha’s Vineyard Transit Authority has introduced 12 electric buses into its fleet and plans to replace its remaining diesel buses with electric models.
- New Bedford: More than 25% of the city’s passenger fleet has been converted to electric vehicles, believed to be the highest percentage of electric vehicles in any municipal fleet in Massachusetts.
- Newton: The Newton Power Choice program offers residents and businesses a default level of 60% renewable electricity, higher than any other municipal aggregation program in the Commonwealth.
- Northampton, Amherst, and Pelham: Local leaders are exploring a Community Choice Energy PLUS program that would provide residents and businesses with a higher percentage of renewable electricity while investing in local projects to reduce emissions.
- Pioneer Valley: The ValleyBike Share program offers an affordable and green alternative transportation network, with more than 500 bicycles available in six communities.
