Co-executive directors of the Home Energy Efficiency Team (HEET), Zeyneb Magavi and Audrey Schulman both entered the climate change fight as mothers concerned for the futures of their children. In this episode, they share the history of their work on fixing super-emitting natural gas leaks in their neighborhood and across the state of Massachusetts. They tell the story of building relationships with natural gas utility executives to make a meaningful reduction in GHG emissions which led to the next major challenge: What is the future of a natural gas systemin a world that needs to eliminate the use of fossil fuels? We discuss HEET’s role in developing the geo micro district, a neighborhood-scale renewable energy network for heating and cooling buildings. They explain the technology but also how its alternative business model offers a cost-effective path forward for our utility companies and their workers as we replace our aging natural gas infrastructure.
