US Geothermal Tax Credits in 2026: What Is Actually Still Alive After OBBBA For an industry that spent more than a decade building financial models around a stable federal incentive structure, 2026 has been a year of whiplash. The 30% federal geothermal tax credit that developers and homeowners built forecasts around is gone in one form and still alive in another, and even the IRS’s own public guidance has been confusing enough to trigger uncertainty across the market. That confusion is not a minor clerical issue. It is shaping investment decisions, contractor sales pitches, homeowner timelines, and project finance assumptions right now. If you work in geothermal, the key question is no longer whether federal incentives exist, but which incentive applies, to which project type, and under what ownership structure. The law that changed the timeline To understand where things stand in 2026, you have to start with the Inflation Reduction Act of 2022, which created a long runway for clean e...
Greece is sitting on a hidden treasure trove right beneath its feet not gold or oil, but something far more sustainable and exciting: geothermal energy. By: Robert Buluma In mid-December 2025, the Ministry of Environment and Energy (ΥΠΕΝ) took a major step forward by publishing two key ministerial decisions that officially classify geothermal fields across the country. The first decision (ΥΠΕΝ/ΔΑΠ/142903/684, published in Government Gazette ΦΕΚ 7320/Β/2025) designates 14 geothermal fields of local interest, featuring temperatures ranging from 30°C to 90°C—perfect for direct-use applications like district heating, greenhouse agriculture, spa tourism, aquaculture, and even small-scale electricity generation. The second decision upgrades the Stypsi field on Lesvos to national interest status (based on updated data from ΔΕΗ Ανανεώσιμες), with temperatures exceeding 90°C and reservoir depths of 250–600 meters. This opens the door to larger-scale, high-enthalpy geothermal power production. W...
