The Retrofit Revolution: How GreenFire Energy Is Unlocking Geothermal Power Without Drilling a Single New Well By: Robert Buluma While much of the geothermal energy sector has been focused on breakthrough drilling techniques—deeper wells, hotter reservoirs, and complex engineered systems—a quieter revolution has been unfolding in the background. Instead of chasing entirely new subsurface frontiers, one company has chosen a radically simpler question: What if the answer was already in the ground? GreenFire Energy is advancing a retrofit-first geothermal strategy that targets one of the most overlooked opportunities in the global energy transition: existing wells that are underperforming, depleted, or completely abandoned. Rather than drilling new holes into the Earth, the company is reusing the infrastructure that already exists—turning stranded assets into continuous sources of clean, baseload electricity. This approach is not just technically elegant. It may also be one of ...
Croatia Approves Geothermal Exploration in Kotoriba: No Full Environmental Impact Study Required By: Robert Buluma Croatia has taken a decisive step forward in its clean energy transition with a new approval that underscores its commitment to renewable energy development. The Ministry of Environmental Protection and Green Transition has ruled that the upcoming geothermal exploration project in Kotoriba—specifically in Zones 2 and 3—does not require a full Environmental Impact Assessment (EIA). This decision effectively allows Viola Energy Generation d.o.o. to proceed with drilling up to four geothermal exploration wells, marking a major milestone for the country’s geothermal sector. As Europe accelerates its shift toward sustainable and energy-secure solutions, Croatia’s proactive stance positions it as a rising leader in geothermal development within the region. A Strategic Decision for Croatia’s Renewable Energy Future In its resolution dated 30 October 2025 , the Ministry concluded...
