Himachal Pradesh is taking bold steps to unlock its geothermal energy potential, positioning itself as a pioneer in India's renewable energy landscape.  By:  Robert Buluma Image: Himachal Pradesh Geothermal Hotsprings Chief Minister Thakur Sukhvinder Singh Sukhu recently announced during a high-level review meeting with senior officers that the state is actively pursuing the harnessing of geothermal resources. This move forms a critical part of the government's long-term strategy to combat climate change, achieve energy security, and reduce dependence on fossil fuels. The announcement, made on January 22, 2026, in Shimla, underscores Himachal Pradesh's ambition to become India's first Green Energy State by 2026. The target is clear: meet over 90% of the state's energy needs—currently around 13,000 million units annually—through renewable sources. While the state has long excelled in hydropower, generating substantial clean power from its rivers, it is now diversifyi...

Harnessing Earth's Fury: The Pause in Switzerland's Geothermal Ambitions By: Robert Buluma In the heart of Switzerland, where alpine peaks pierce the sky and pristine lakes mirror the eternal snow, a quiet revolution was brewing beneath the surface. Imagine tapping into the planet's own fiery core to power homes and heat communities—clean, renewable, and seemingly infinite. That's the allure of geothermal energy. But in the quaint region of Inwil and Perlen in Kanton Luzern, this dream has hit a snag. The Zentralschweizerische Kraftwerke AG (CKW), a key player in Switzerland's energy landscape, has slammed the brakes on a promising geothermal project. Announced in 2023, the initiative promised to deliver electricity to 4,000 households and heating to 6,500 more, all from the depths of the Earth. Yet, as of January 21, 2026, it's on indefinite pause. Why? The underground didn't cooperate as hoped. This story isn't just about a stalled drill; it's a w...

Beneath the Pavement: Manchester’s Hidden Geothermal Power Could Redefine Urban Energy By:  Robert Buluma What if the future of clean energy isn’t offshore, on rooftops, or in remote landscapes—but buried silently beneath the concrete of our cities? In Manchester, scientists have just delivered a powerful reminder that the ground beneath our feet may be one of the UK’s most underappreciated energy assets. Beneath a modest car park at the University of Manchester lies a geothermal resource capable of supplying clean, continuous energy on a scale that could power tens of thousands of homes. This is not a speculative vision or a distant ambition. It is the result of rigorous science, modern geophysical imaging, and a rethinking of how cities can participate in the energy transition. And it could change everything.  A Breakthrough Hidden in Plain Sight The discovery emerged from a knowledge exchange project between the University of Manchester and Metatek, a remote sensing compan...

Breakthrough in Polish Geothermal Energy: Hot Waters Over 100°C Discovered in Podhale By:  Robert Buluma Image:  Polish Geothermal Energy: Hot Waters Over 100°C Discovered in Podhale In late December 2025, Poland's Chief National Geologist, Professor Krzysztof Galos, announced a significant discovery in the Podhale region: access to geothermal waters exceeding 100°C. This revelation came from the Bańska PGP-4 borehole in Szaflary, marking a potential turning point for renewable energy in the country. The drilling rig at the Bańska PGP-4 site in Szaflary, Podhale , a symbol of Poland's ambitious push into deeper geothermal resources. The Unique Geology of Podhale The Podhale basin, nestled between the Tatra Mountains and the Pieniny Klippen Belt, has long been recognized as Poland's premier geothermal hotspot. Its geological structure is unparalleled in the country: a reservoir formed by Paleogene sandstone-shale formations up to 3 km thick, overlying Mesozoic carbonate rock...

New High-Temperature Downhole Fluid Sampler – A Major Step Forward in Geothermal Research and Sustainable Utilization By:  Robert Buluma January 17, 2026 Alphaxioms Geothermal News Iceland’s geothermal resources have long been the cornerstone of the country’s energy independence, providing nearly 100% of space heating and a substantial share of electricity production from renewable sources. Since its establishment, the Icelandic Institute of Natural History’s geothermal division — today known as ÍSOR (Iceland GeoSurvey) — has placed strong emphasis on research, innovation, and the development of cost-effective technologies to meet the challenges of geothermal utilization. The latest milestone in this continuous effort is the successful development and field deployment of a high-temperature downhole fluid sampler, capable of collecting authentic reservoir fluid samples at extreme temperatures. What is the High-Temperature Downhole Fluid Sampler and Why Does It Matter? In convention...

Advancements in Geothermal Energy: New Zealand's Ngā Tamariki Expansion Leads the Way By:  Robert Buluma Image:  Mercury NZ Delivers Fifth-Generation Unit at Ngā Tamariki – Strengthening Clean Energy Supply Geothermal energy, harnessed from the Earth's internal heat, represents one of the most reliable and sustainable sources of renewable power available today. Unlike solar or wind, which depend on weather conditions, geothermal provides consistent baseload electricity, making it a cornerstone for energy security in regions with suitable geological features. As the world grapples with climate change and the need to transition from fossil fuels, geothermal is gaining renewed attention. In 2026, global investments in geothermal are surging, with projections indicating annual funding could reach nearly $9 billion by 2030. This growth is driven by advancements in next-generation technologies, such as enhanced geothermal systems (EGS), which expand accessibility beyond traditional ...
