Who We Are

Our Missioncfltankbanksmaller

HEET is a Cambridge-based non-profit organization.

Our mission is:

  • to catalyze community engagement and develop hands-on educational opportunities
  • to advance energy efficiency skills and clean energy knowledge
  • to achieve climate stability and create resilient communities.

HEET is one of the only organizations in the Boston area that provides free, practical education to local communities, teaching people how to reap the benefits of energy and water efficiency measures.

To fight climate change, we must all work together. HEET organizes Energy-Upgrade Work-Parties where volunteers under the guidance of skilled team leaders perform the necessary tasks to make a building more energy efficient. A survey has shown that over 70% of our volunteers use four or more of the hands-on skills we teach to reduce energy in their own homes. The work also lowers energy bills for the host organization, allowing it to spend more on helping its community.

We also partner with local governments on our initiatives such as the Cambridge Solar Challenge during which the number of residential solar installations increased ten-fold over the normal rate of solar installations in Cambridge.

Since its inception, HEET has made a deep commitment to serve low-income communities. Many non-profits such as preschools, food pantries, and community centers lack the in-house knowledge and resources to repair and operate their buildings efficiently. The resulting energy bills can be crippling. These non-profits function as the backbone of the local economy and are a measure of the wellbeing of the community. HEET helps them save money and reduce energy use, inspiring them to leapfrog to a cleaner, smarter energy future.

For its efforts to cut carbon and its commitment to creating resilient communities, HEET has received significant recognition in the past five years.

Our Scope

We work in the Metro Boston Area, primarily Cambridge and Boston. Some of the towns we have worked in include Arlington, Dorchester, Hyde Park, Maynard, Roxbury, Somerville, Waltham, Watertown, and Worcester.

We have provided our services to methadone clinics, homeless shelters, food pantries, community centers, and many historic churches.

We empower urban communities to utilize the Mass Save services and rebates available to them. These underserved communities pay for these services through a surcharge on their energy bills but tend to use them less than wealthy suburban neighborhoods.

From experience, we have found that working with three critical stakeholder groups—residents, non-profits, and small businesses—can catalyze the deepest transformation in a community’s mindset, its economic wellbeing, and its impact on the environment.
