HEET

About

Founded in 2008, HEET is a ngo headquartered in Boston, United States with approximately 50-200 employees specializing in Geothermal, Energy Storage.

HEET (Home Energy Efficiency Team) is a nonprofit climate solutions incubator based in Boston, Massachusetts. The organization operates as a thermal energy innovation hub with a mission to drive systems change through an ethical and efficient thermal energy transition. HEET's core work includes: (1) Methane emissions reduction—mapping gas leaks, conducting research on leak detection and repair, and advocating for policies to address high-volume leaks that are primary sources of atmospheric methane; (2) Health impacts research—investigating chemical composition of natural gas and its effects on indoor air quality and public health, particularly for vulnerable populations; (3) Networked geothermal development—proposing and advancing the concept of gas utilities transitioning to thermal utilities by delivering heating and cooling through networked ground-source heat pumps connected via shared loops in existing gas infrastructure; (4) Energy efficiency—promoting residential and building energy efficiency upgrades, particularly in low-income and communities of color; and (5) Equitable energy transition—ensuring the transition to clean thermal energy meets the needs of all stakeholders including low-income communities, utility workers, and future generations. HEET maintains strict independence, accepting no funding from utilities or industry. The organization has contributed to significant policy outcomes in Massachusetts, including methane-focused legislation and utility pilot projects for networked geothermal systems, with Eversource Gas installing the first utility-owned networked geothermal system in Framingham, Massachusetts.
