Prenzlau’s Geothermal Breakthrough: A Decisive Step Toward a Fully Renewable Heat Future By: Robert Buluma The city of Prenzlau, located in northeastern Germany, has reached a major milestone in its transition toward sustainable energy. In December 2025, Stadtwerke Prenzlau announced a decisive breakthrough in its geothermal project after successfully encountering geothermal water at a depth of 983 meters. This discovery represents a critical step forward for the city’s ambition to fully decarbonize its heat supply and positions Prenzlau as a leading example of how medium-sized towns can harness geothermal energy for district heating. The geothermal water discovered during drilling operations is estimated to be around 200 million years old and is contained within a saline sandstone formation deep underground. With a temperature of approximately 44°C and a planned production rate of 130 cubic meters per hour, the resource offers a reliable and continuous source of renewable heat. A test...

Connecticut’s Groundbreaking Geothermal Network: Heating the Future in New Haven By Robert Buluma   In the heart of New Haven, Connecticut, a quiet but revolutionary clean-energy transformation is unfolding beneath city streets. What lies underground could redefine how American cities heat and cool their buildings. New Haven has officially begun construction of Connecticut’s first networked geothermal energy system, a project designed to provide ultra-efficient, low-emission heating and cooling to the city’s historic Union Station and a major new public housing development nearby. More than a local infrastructure upgrade, this initiative marks a decisive step toward New Haven’s ambitious climate goal: fully decarbonizing municipal buildings and transportation by 2030. Even more significantly, it positions the city as a blueprint for how thermal energy networks could be scaled across Connecticut and eventually, the United States. Union Station: A Historic Landmark Meets Clean Energy...

Fervo Energy's $462 Million Geothermal Gold Rush: Google Joins the Heat By:  Robert Buluma December 10, 2025 In the fast-evolving world of clean energy, where solar panels dominate skylines and wind farms stretch across horizons, a deeper and quieter revolution is rising from beneath our feet. Fervo Energy, the Houston-based innovator in enhanced geothermal systems (EGS), has just announced an astonishing $462 million Series E funding round. This isn’t just another climate-tech investment,it's a tectonic moment for geothermal energy. The round was led by   B Capital , joined by major players including Google , Tesla co-founder JB Straubel, and nuclear industry leader Kris Singh. With continued backing from Breakthrough Energy Ventures and Devon Energy, Fervo’s total funding now exceeds $1.5 billion. Why the sudden rush? As AI-driven data centers consume unprecedented amounts of electricity and political winds shift around renewable priorities, geothermal’s promise of 2...

Jakarta, September 2025   In a move that could change how Indonesia leverages its enormous geothermal endowment, PT Pertamina Geothermal Energy Tbk  (PGE) and PT  Toyota Motor Manufacturing Indonesia (TMMIN) signed a joint declaration to develop a green hydrogen ecosystem in Indonesia.  By:  Robert Buluma The announcement  made at the 11th Indonesia International Geothermal Convention & Exhibition (IIGCE) in Jakarta  signals an ambition to turn geothermal heat into a strategic feedstock for low-carbon fuels and industrial feedstocks, not just electricity. Why this matters Indonesia sits on some of the world’s richest geothermal resources. Traditionally those resources have been used to generate baseload electricity; PGE’s partnership with Toyota broadens the conversation: use geothermal power and heat to produce green hydrogen, then convert that hydrogen into transport fuels, ammonia, methanol, or industrial hydrogen for heavy industry. That pivot...
