Eavor Technologies achieved a significant breakthrough in December 2025 when its flagship closed‑loop geothermal project in Geretsried, Germany, began delivering electricity to the grid.  By:  Robert Buluma  The Canadian startup had completed the first of four planned underground loops and intended to start construction on the second loop in early 2026. That timeline has now been revised. The company encountered substantial engineering difficulties while drilling the initial wells, including borehole instability, slow penetration rates, equipment failures, and cement‑casing issues that allowed fluid to leak between parallel drilling rigs. Although Eavor resolved those problems, the setbacks increased both time and cost. As a result, the firm is now looking for new project partners and investors to help complete the next phase. The Geretsried site, located south of Munich, was chosen precisely because it is geologically challenging. Previous conventional geothermal attemp...

The $765 Million Swap: How the Trump Administration Is Dismantling U.S. Offshore Wind One Lease at a Time By:  Robert Buluma  The administration's latest buyback deal with Invenergy marks a strategic pivot from renewable energy to fossil fuels—and signals a new chapter in America's energy wars. I. Introduction: A New Front in the Energy Wars On June 17, 2026, the U.S. Department of the Interior announced a landmark settlement agreement with Invenergy, North America's largest privately held developer of independent power infrastructure. The deal: Invenergy would voluntarily terminate four offshore wind leases—located in the New York Bight, off the Central Coast of California, and in the Gulf of Maine—in exchange for $765 million in reimbursements. In return, the company committed to redirect those funds toward natural gas‑fired power plants in Indiana, Wisconsin, Iowa, Kansas, and Missouri, as well as geothermal power generation projects in the Western United States. The Inv...

Templin Lies on a Hot River: How Geothermal Energy Could Secure Affordable District Heating By:  Robert Buluma  A Hidden Treasure Beneath the Uckermark For more than 25 years, the NaturTherme Templin has been pumping thermal brine from a depth of 1,650 meters, using it as a healing remedy. The water that rises from this depth has a temperature of 57.7 degrees Celsius—impressive by any measure, but only a fraction of what lies beneath. During a routine annual check-up of the production well, geothermal specialists from Neubrandenburg posed a question that would set in motion one of the most ambitious energy projects in the region: Did the city even know what treasure it was sitting on? The answer, it turned out, was no. And that realization has since transformed Templin into a pioneer in Germany's heating transition. The Assessment That Changed Everything The city was already working on a heating concept aimed at achieving a sustainable, fossil-fuel-independent supply. The Natu...

Advanced Drilling Technologies in Geothermal Energy Introduction Geothermal energy represents one of the most promising sources of clean, baseload renewable power. The Earth's subsurface heat is virtually inexhaustible—estimates suggest that at 5 km depth, the planet stores approximately 140 × 10⁶ EJ of heat, enough to meet global energy demands for about two millennia if only 1% were extracted. Yet despite this enormous potential, geothermal development has historically been constrained by a single persistent bottleneck: drilling. Drilling accounts for 30% to 57% of total geothermal project costs, making it the primary economic barrier to wider deployment. The challenges are formidable—hard crystalline rocks, extreme temperatures exceeding 374°C, high pressures, and corrosive downhole environments all push conventional drilling technologies to their limits. However, a new generation of advanced drilling technologies is emerging that promises to fundamentally transform what is poss...

The Geothermal Dark Horse Emerges: SpaceX Alum Raises $22M to Turn Rocket Engines into Power Plants for Data Centers By:  Robert Buluma  In the grand narrative of global energy transition, nuclear fusion often grabs sci‑fi headlines, while solar and wind bask in policy support and investor enthusiasm. Yet a force from deep underground is quietly rising, storming center stage as an unlikely contender. This week, Critical Energy—a startup founded by a SpaceX alumnus—announced a $22 million funding round to transform rocket‑engine technology into modular geothermal turbines, aiming to deliver steady, clean baseload power to the data centers that power the artificial‑intelligence age. The capital injection is not merely a bet on a fledgling company; it is a signal that geothermal energy is emerging as the next “unicorn” sector in clean tech. With AI compute demand growing exponentially, Critical Energy appears precisely at the intersection of two massive waves: the tech industry’s...
