New techniques borrowed from oil and gas fracking are unlocking heat from deep underground in places far beyond traditional hot springs. Private capital has poured more than $1.5 billion into next-gen geothermal since 2021, and companies like Ormat and Sage Geosystems are partnering to bring commercial projects online by 2027.
