From Waste Heat to Power: Indonesia’s Lahendong Breakthrough and the Future of Geothermal Efficiency By: Robert Buluma In the global transition toward clean, resilient, and sustainable energy systems, geothermal power has consistently stood apart. Unlike solar or wind, it does not depend on weather conditions. Unlike fossil fuels, it does not emit significant greenhouse gases. It is stable, reliable, and—perhaps most importantly—immensely underutilized. Yet even within geothermal, a quiet inefficiency has persisted for decades: waste heat . Now, Indonesia is rewriting that narrative. A landmark agreement between  Pertamina Geothermal Energy (PGE) ,  PLN Indonesia Power , and  Perusahaan Listrik Negara (PLN) signals a pivotal shift—not just for Indonesia, but for the global geothermal sector. The trio has finalized electricity tariff terms for the Lahendong Bottoming Unit , a 15 MW geothermal expansion project that transforms previously wasted heat into usable electric...

Tiny North Carolina Town Takes a Big Step Toward Geothermal Energy By: Robert Buluma In the quiet rural landscape of , a bold energy revolution is quietly taking shape. What appears to be just another small American town is, in reality, positioning itself at the forefront of a transformative clean-energy movement—one that could redefine how underserved communities access power, reduce costs, and build resilience. At the heart of this transformation is a nearly $300,000 seed grant secured by . This funding marks the first tangible step toward deploying a neighborhood-scale geothermal system—also known as a thermal energy network—that promises to deliver heating, cooling, and hot water without reliance on fossil fuels. A Vision Born from Necessity For decades, Enfield has struggled with high energy costs, aging infrastructure, and systemic underinvestment. Residents routinely face electricity bills that can soar to unsustainable levels, especially during extreme weather seasons. But u...

Geothermal Lithium Extraction: Costs, Companies & Profitability (2026) By: Robert Buluma 🔥 Introduction As the global transition to clean energy accelerates, lithium has become one of the most strategically important resources of the 21st century. It powers electric vehicles, grid-scale storage systems, and a growing ecosystem of battery technologies. Yet, traditional lithium extraction methods—hard rock mining and evaporation ponds—are increasingly under scrutiny for their environmental footprint, long development timelines, and geographic concentration. Against this backdrop, geothermal lithium extraction is emerging as a compelling alternative. By leveraging existing geothermal energy systems, this approach enables the simultaneous production of renewable electricity and lithium from subsurface brines. It represents a rare convergence of energy and mineral extraction—one that could reshape supply chains while reducing environmental impact. But beneath the promise lies a crit...

House Bill to Repurpose Oil Wells for Alternative Energy: A Turning Point in the Energy Transition The United States House of Representatives has passed a significant piece of legislation aimed at transforming the future of aging oil and gas infrastructure. The bill allows depleted and underutilized oil wells to be repurposed for alternative energy applications, marking a strategic shift in how fossil fuel assets are viewed in the broader energy transition. Instead of being abandoned as environmental liabilities, these wells are now being repositioned as potential gateways to cleaner and more diversified energy systems. This move reflects a growing global trend: the transition from fossil-fuel dependency toward integrated energy systems that maximize existing infrastructure while reducing environmental impact. The legislation is not just about energy policy—it is about reimagining industrial legacy systems as platforms for innovation. Reframing Oil Wells as Energy Assets, Not Waste ...

Olkaria Geothermal Field: Africa’s Energy Giant With Untapped Billions Beneath Deep within Kenya’s Great Rift Valley lies a geothermal powerhouse that has quietly redefined Africa’s energy landscape—Olkaria Geothermal Field. For decades, Olkaria has stood as a symbol of resilience, innovation, and baseload stability in a continent long challenged by energy insecurity. But here’s the uncomfortable truth:   Olkaria is not yet operating at its full potential. Beneath its steam fields, pipelines, and turbines lies a far more complex, under-optimized system—one that, if properly engineered and integrated, could unlock billions of dollars in additional value beyond electricity generation. This is not just a story about megawatts.   This is a story about missed integration, untapped resources, and the next frontier of geothermal dominance. 1. The Scale of Olkaria — Impressive, Yet Fragmented Olkaria is one of the largest geothermal complexes in the world, with Kenya’s total...

A New Geothermal Frontier at Hellisheiði: Iceland’s Hidden Heat Revolution Emerges from Meitlar Introduction: When the Earth Speaks Again In the quiet, volcanic landscapes of Iceland, where fire and ice have coexisted for millennia, a new chapter in geothermal energy is quietly unfolding. On April 16, 2026, a major announcement emerged from Orkuveitan (Reykjavík Energy), revealing the discovery of a previously unidentified geothermal area at Meitlar on Hellisheiði. If confirmed by a third exploratory well, this discovery could reshape not only Iceland’s energy landscape but also the global conversation around deep geothermal exploration, energy security, and sustainable heat production. This is not just another geological update. It is a signal—an indication that even in one of the most studied geothermal regions on Earth, the subsurface still holds untapped surprises. Hellisheiði: A Global Benchmark for Geothermal Energy Hellisheiði is already one of the most important geotherma...

Power Beneath the Surface: How Geothermal Lithium Is Rewriting the Energy Future In the global race toward clean energy and electrification, a quiet revolution is unfolding deep beneath our feet. It is not driven by wind turbines slicing through the sky or solar panels stretching across deserts, but by something far more constant, more reliable—and arguably more transformative. Geothermal energy, long recognized for its ability to deliver steady baseload power, is now stepping into an entirely new role: powering the extraction of one of the world’s most critical minerals—lithium. At the center of this breakthrough stands (GEL) , a company redefining what geothermal projects can achieve. Their latest milestone—securing funding under the UK’s ambitious DRIVE35 programme—signals not just a win for one company, but a turning point for the entire clean energy ecosystem. This is not just a story about energy. It is a story about convergence—where heat, chemistry, engineering, and policy c...
