Heat pumps are a more sustainable and efficient way to heat homes than to conventional gas heat, but they’re often too expensive for homeowners to install. Meet the GeoGrid, an underground geothermal heat pump network that could make the technology more efficient and accessible. Home Energy Efficiency Team (HEET) is a nonprofit working with utilities to develop GeoGrids in residential neighborhoods. We spoke to HEET Executive Directors Audrey Schulman and Zeyneb Magavi about heat pumps and the advantage to connecting them via a GeoGrid approach.
Heat pumps are often suggested as a way for homes to improve energy efficiency and reduce carbon emissions. However, their high price tag has traditionally made them inaccessible to many. By installing neighborhood wide geothermal technology, GeoGrids could provide the solution.
More than 40 percent of energy generated in the United States is used to power buildings, from heating and lighting to igniting gas-powered stoves. Decarbonizing buildings could put a serious dent in overall energy consumption, but it’s not an easy task.
