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...
A new geothermal energy project is starting in Switzerland with a geophysical measurement campaign in Gruyère. Geophysical measurement campaign During the entire month of November, special vehicles will travel the streets of the Gruyère district to map the subsurface and assess the presence of geothermal water. If the potential is confirmed, Géothermie Préalpes SA can consider exploiting this local, renewable, clean and safe energy source. This geophysical campaign follows a preliminary study indicating interesting hydrothermal potential in Gruyère. The geophysical measurements enable the acquisition of data to better understand the subsurface of the region. Special vehicles will send waves into the ground; these are reflected by the various geological layers and picked up by measuring devices called geophones. The analysis of this information will make it possible to create a cartography of the subsurface. Measurements in 18 municipalities Data collection ...
