Nysa May Be Sitting on Vast Geothermal Wealth: Exploratory Drilling to Begin in Spring 2026 By: Robert Buluma Nysa, a historic town in southern Poland, could soon become a regional pioneer in geothermal energy. With the signing of a contract for a geothermal exploratory well, the municipality has officially launched one of the most ambitious renewable energy projects ever undertaken in the Opole Voivodeship. Preparatory works will continue through 2025, with drilling scheduled to begin in spring 2026 and continue for approximately six months. The goal is clear: to confirm whether deep beneath Nysa lie geothermal waters capable of transforming the town’s heating system, economy, and environmental footprint. A Strategic Step Toward Energy Independence According to Nysa Mayor Kordian Kolbiarz, geothermal energy represents far more than a technological experiment. It is a strategic investment in the town’s future. If the geothermal resources are confirmed, they could supply heat and hot wa...

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...

El Salvador's Volcanic Awakening: How the Berlin 2 Plant is Powering a Nation's Bold Leap into the Future By: Robert Buluma Imagine a land where ancient volcanoes rumble beneath the surface, not as harbingers of destruction, but as silent guardians of boundless energy. In El Salvador, the smallest nation in Central America, this isn't just poetic fancy,it's reality. On December 13, 2025, amid the lush hills of Usulután, the inauguration of the Berlin 2 Binary Cycle Plant marked a seismic shift in the country's energy landscape. With a thunderous applause from engineers, officials, and locals alike, President Nayib Bukele's vision for a modern, self-sufficient El Salvador ignited into life. This isn't just another power plant; it's a beacon of innovation, harnessing the Earth's fiery core to light up millions of homes. Buckle up as we dive into this captivating story of renewal, resilience, and raw power. El Salvador has long been a geothermal powerho...

Harnessing the Earth's Hidden Fire: UGM's Revolutionary Leap into Geothermal Cooling for a Cooler, Greener Indonesia Posted on December 14, 2025 | By  Robert Buluma Picture this: It's a blistering afternoon in Jakarta, the kind where the humidity clings to your skin like a second layer, and the air conditioner hums relentlessly, devouring electricity powered by distant coal plants. The planet warms, sea levels rise, and our energy bills skyrocket. But what if the solution to cooling our cities lay not in the sky's fickle sun or the wind's whisper, but deep beneath our feet,in the simmering heat of the Earth itself? This isn't science fiction; it's the bold vision being championed by Universitas Gadjah Mada (UGM), Indonesia's premier academic powerhouse, as they ignite a geothermal revolution for building cooling systems. In a move that's as groundbreaking as it is timely, UGM is spearheading the transition to clean energy by tapping into Indonesia...

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...

First Utility-Owned Geothermal Network Set to Double with DOE Grant , A Bipartisan Clean Energy Win By: Robert Buluma In a political climate where clean energy funding is under siege, geothermal is emerging as the unexpected survivor. Just days ago, the U.S. Department of Energy greenlit an $8.6 million grant to expand the nation's pioneering utility-led geothermal heating and cooling network in Framingham, Massachusetts. This move, finalized under the Trump administration, signals that geothermal – reliable, efficient, and domestic – might just be the renewable technology that transcends partisan divides. The Framingham Pilot: A Groundbreaking Start Launched in 2024 by Eversource Energy , the Framingham project marked a U.S. first: a utility-owned networked geothermal system serving an entire neighborhood. Spanning residential homes, a school, a firehouse, and low-income housing, the initial phase taps into stable underground temperatures around 55°F via dozens of boreholes drill...

Hyundai E&C Breaks Record: Building the World’s Largest Single-Unit Geothermal Power Plant in Indonesia By:  Robert Buluma In a remarkable feat of engineering, Hyundai Engineering & Construction ( Hyundai E&C) has just completed the Sarulla Geothermal Power Plant (Sarulla GPP) in North Sumatra, Indonesia now officially recognized as the world’s largest single-unit geothermal power plant with a capacity of 330 MW. This milestone not only showcases Korean engineering excellence on the global stage but also marks a significant step forward for clean, reliable renewable energy in Southeast Asia. A Giant Leap for Geothermal Energy Located in the Sarulla region of North Sumatra, the plant consists of three units that together deliver 330 megawatts of clean electricity enough to power approximately 2.1 million Indonesian households. What makes Sarulla truly special is its single-unit design. While many geothermal projects around the world are built in smaller, modular phases...

Exclusive interview with Exergy : discover the new Gemini dual-flow radial outflow turbine, the first single-unit ORC solution for 30–60 MW geothermal projects, offering up to 30 % lower costs and 99 % availability. By:  Robert Buluma .   An interview with  Luca Pozzoni -  Deputy CEO | Group CFO - Exergy International and the Exergy Team 1. Can you walk us through the key design innovations in your new Gemini turbine and how it differs from previous models? The major innovation of the Gemini turbine lies in the dual-flow configuration: unlike conventional radial outflow turbines which are equipped with a single bladed overhung rotor disk, the Gemini features a double-side bladed rotor disk mounted in a between-bearing configuration. This enables the efficient processing of significantly larger volumes of fluid, leading to higher power output having basically two radial outflow turbines in a single machine with enhanced operational stability and simplified mainte...

Big Blind: The Geothermal Discovery That Changes Everything By: Robert Buluma Utah startup  Zanskar Geothermal quietly dropped one of the most important announcements in American energy in decades. They discovered and confirmed “Big Blind” ,the first completely blind, commercial-grade geothermal system found in the United States in over thirty years. Let that sink in. No hot springs.   No fumaroles.   No steaming ground.   No prior wells.   Zero surface expression whatsoever. Just desert, sagebrush, and – 7,000 feet below,  a reservoir hot enough and permeable enough to support gigawatt-scale power production. This isn’t incremental progress. This is a paradigm breaker. Why “Blind” Discoveries Matter So Much For the last 40 years, geothermal development in the U.S. has been geographically handcuffed. You could only build plants where nature advertised the resource on the surface – think Yellowstone, The Geysers, or Imperial Valley. Ever...
