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.

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...
Cornwall’s Geothermal Gamble: Delay Sparks Debate in Slaughterbridge Published: 22 August 2025 By: Robert Buluma Cornwall at a Crossroads: Energy Opportunity or Environmental Risk? Slaughterbridge, Cornwall – A decision that could have marked a major leap toward renewable energy in Cornwall has been put on pause.

Supporters say it would reduce Cornwall’s reliance on fossil fuels, create jobs, and inject roughly £2 million into the local economy. Sound appealing, right? Fear Benea...
