Mass Save's outreach program aims to bring energy efficiency to homes across state

The state's energy program, Mass Save, has helped residents get things like free energy-efficiency assessments and rebates for upgrading insulation and windows for more than a decade.

But not everybody is buying in: recent state reports show a lot of residents aren't using the services, especially residents who aren’t proficient in English.

Mass Save's Community First Partnership is working to change that, starting in Lowell, which has one of the largest Latino populations in the state.
