Eversource Gas breaks ground on first networked geothermal installation

Framingham, Massachusetts is the site of the first gas-utility-run networked geothermal system, ever! Once complete, this network of water-filled pipes, heat pumps and boreholes will provide heating and cooling to a community of over 40 houses, apartments, and commercial buildings, including low-income housing.  How did we get here?  HEET first pitched the idea of networked…

A conversation with Cary Smith: A founding innovator of networked geothermal

Cary Smith, owner of Sound Geothermal Corporation and a principal with the Grey Edge Group, has designed countless geothermal systems across the country. This fall, Cary visited HEET at Eversource’s worksite in Framingham, Massachusetts, where the first utility-run networked geothermal system is currently being installed. I (Carrie, HEET Director of Communications) had a chance to…

Weatherizing for the winter 

This fall, HEET hosted a work day with the Harvard Kennedy School of Government to insulate an attic at First Church Nazarene in Central Square. Jason Taylor, HEET board member and a weatherization expert, estimates this work will reduce the church’s bills by about 800 therms—or close to $800 annually in heating cost reduction.  As…

Introducing the Falcon Curve

Sometimes, you need to define a challenge in order to communicate how you are solving it.  To reach carbon reduction goals nationally, we must transition our buildings—a huge source of greenhouse gas emissions—off of fossil fuels. In carrying out this energy transition to electricity powered by renewable energy, we need a plan that minimizes cost…

This unlikely crew is gathered on an Eversource Gas worksite, where the gas utility is installing an energy system to heat and…

Home is Where the Pipeline Ends

New research by HEET, Harvard, and PSE Health Energy finds chemical contamination in natural gas delivered to homes. Read the study here. In 2015, a natural gas storage facility near Porter Ranch, California, sprung a leak. It went on to release nearly 100,000 tons of gas into the air over four months, becoming the largest gas…
