Spain's average PV curtailment rate stands at 3.83%, but in Badajoz province it surpasses 37%, according to a nine-month analysis by Circe, a nonprofit research center founded by the University of Zaragoza. Grid constraints, system security, and market oversupply are identified as the three key drivers.
The IEA's Ocean Energy Systems programme has published its 2025 Annual Report, documenting consistent advances in tidal, wave, and other marine energy technologies. The report signals growing momentum in a renewable energy segment that could complement solar and wind in future clean energy mixes.
The AI boom is pushing electricity grids to their limits, and a nationwide debate is underway in the US over whether tech giants should be forced to shoulder the cost of grid upgrades they are driving.
A federal judge in West Virginia has blocked the U.S. Army Corps of Engineers from issuing a Clean Water Act permit for a mountaintop removal coal mine on Coal River Mountain. The ruling came in response to a lawsuit filed by several environmental organizations, including Sierra Club and Appalachian Voices.
SolarEdge has unveiled the CSS-OD 197, a 197 kWh commercial and industrial battery cabinet based on LFP chemistry that can scale up to 1 MW / 4 MWh. The system is already being deployed across key European markets including Germany, Austria, Switzerland, the Netherlands, Poland, and France.
Turboden America and Fervo Energy have signed a three-year agreement to supply ORC units for 35 GeoBlocks, representing a combined 1,750 MW of geothermal capacity in Utah. The partnership aims to cut lead times through standardised modular deployment.
An international research team has unveiled an AI-driven robotic system that autonomously designs, fabricates, and optimizes perovskite solar cells, testing over 50,000 devices and reaching a certified efficiency of 26.5% (peak 27%). The breakthrough could accelerate the path from lab to commercial production.
The International Energy Agency (IEA) reports that in 2025, solar energy surpassed all other energy sources in newly added capacity worldwide — a historic global first. While overall energy demand growth slowed, electricity consumption continued to rise strongly.
Researchers at the University of Naples Federico II found that green hydrogen production at Mediterranean ports can cost as little as €2.5/kg in hybrid systems combining renewables with grid power. Solar proved the most consistent renewable resource, while the broader hydrogen industry sees major new projects and electrolyser breakthroughs.
Hungary's installed solar capacity crossed 4 GW in Q1 2026 per MNNSZ — an 18% year-over-year increase.
