Unlocking Hawaii’s Hidden Cooling Power: New Report Reveals Huge Potential for Geothermal Cooling on Oahu (2025) By:  Robert Buluma Could the same volcanic islands that give Hawaii its famous heat also provide the solution to cool its buildings , without crushing the electric grid?   A groundbreaking new report released December 8, 2025, by the University of Hawaiʻi at Mānoa (UHM) and Lawrence Berkeley National Laboratory (LBNL) says the answer is a resounding yes. Shallow geothermal heat exchangers (GHEs) , also known as geothermal heat pumps or ground-source heat pumps ,could dramatically cut cooling costs and electricity demand across Oahu, especially for large buildings like schools, military bases, and university facilities. Here’s everything you need to know about this exciting development in Hawaii geothermal cooling technology. Why Hawaii Is Perfectly Suited for Geothermal Cooling Most of the world uses geothermal heat pumps for heating in cold climates. Hawaii ...
