Wind and Solar Generate Over One-Third of Brazil’s Electricity for the First Time
Wind and solar power supplied 34% of Brazil’s electricity in August 2025, producing a record 19 TWh and surpassing the previous high set in September 2024[1]. This milestone highlights Brazil’s shift toward renewables, even as hydroelectric output fell to a four-year low and fossil fuel generation remained relatively low at 14% of the mix[1].
New U.S. Federal Rules Tighten Deadlines for Wind and Solar Tax Credit Eligibility
The U.S. Treasury released new rules requiring wind and solar developers to start substantial physical work onsite by July 4, 2026, to qualify for federal tax credits, eliminating the previous 5% expenditure option for large projects[3]. Projects beginning construction between September 2, 2025, and July 4, 2026, will have four years to finish, while distributed solar under 1.5 MW can still use the 5% test[6].
U.S. Renewable Energy Market Faces Policy and Tariff Headwinds Beyond 2026
Industry leaders warn that the U.S. is rapidly curtailing renewable energy subsidies and introducing new regulatory obstacles, with most currently financed projects having been initiated before the latest policy turbulence[8]. The future of renewables deal flow after 2026 remains uncertain due to unpredictable swings in tariffs and subsidy reductions[8].
Thailand’s Constant Energy Secures $9.4 Million for Solar and Storage Expansion
Independent power producer Constant Energy raised $9.4 million in green financing from HSBC to expand large-scale solar and battery storage projects in Thailand, supporting the country’s target of 15.6 GW of solar by 2035[5]. The investment will accelerate rooftop, ground-mounted, and floating solar systems, aiding clients in reducing carbon emissions and electricity costs[5].
Solar Price Declines Outpace Previous Forecasts; Perovskite-Silicon Tandems Could Cut Costs Further
Researchers report that historical projections have consistently underestimated the speed of solar and storage price declines, with perovskite-silicon tandem cells potentially reaching 44% efficiency
