“Legislation enacted in 2014 requires gas companies to report gas-leak information annually to the state. Through those disclosures, HEET has been analyzing, geocoding and mapping National Grid’s information, making the raw data more accessible.”

“We shouldn’t be installing new gas infrastructure when we know we’re going to be decarbonizing by 2050,” said Audrey Schulman, founder and co-executive director of HEET, a nonprofit that promotes geothermal energy. “We need to be aggressive about pursuing non-fossil fuel sources of energy.”

‘We have to work with the pieces we have,” said Magavi. “The fastest way forward is to flip utilities’ financing mechanisms and customer networks, all these pieces that we can redirect toward building a better energy system.”

“It’s just fiscally irresponsible, and it sets up a classic utility death spiral,” said Zeyneb Pervane Magavi, co-executive director of HEET, a Cambridge nonprofit that specializes in energy efficiency. “As people move off the gas system, you have fewer people paying for it, meaning they will be shouldering more of the costs. It’s a disaster.”

“We need to avoid rebuilding, basically, a 19th-century infrastructure,” said Nathan Phillips, a professor in the Earth and Environment department at Boston University who lives in Auburndale. “Instead, we need to pivot toward the heating of the 21st century.”

“With widespread deployment of community-scale geothermal systems, utilities could become thermal distribution managers. ‘They would predict thermal demand and make real-time decisions to move or store energy,’ said Zeyneb Magavi, HEET’s co-executive director.”
