The Trump Administration continues to destabilize federal support for renewable energy deployment by eliminating or altering certain Department of Energy offices that support decarbonization of the electric grid. The New York Times first reported that several offices were in place under the Biden administration Department of Energyand that were critical to renewable energy research and deployment for decades, have been replaced or closed in President Donald Trump’s DOE. In a department organizational chart Published Thursday, the Office of Clean Energy Demonstrations, the Office of Fossil Energy and Carbon Management and the Office of Energy Efficiency and Renewable Energy (EERE) are…
Cybrid Technologies announced the first mass shipment of optical conversion films for perovskite tandem solar panels, which it described as the world’s first commercial application of this technology. November 21, 2025 Emiliano Bellini Cybrid technologies announced the first mass shipment of optical conversion films for perovskite tandem solar panels, which it described as the world’s first commercial application of this technology. The product was shipped to a major, unnamed U.S. photovoltaic manufacturer. The optical film converts harmful ultraviolet light into visible light that is beneficial to perovskite materials, significantly improving weather resistance and longevity, the company said. Laboratory results indicate…
The energy price cap, set by UK energy regulator Ofgem, has risen by 0.2%, meaning the average UK household would have to pay £1,758 for energy every year. The price cap is set every three months, and the increase is equivalent to a monthly bill increase of 28 pence per month, from January to March, before the new price cap is set for the April to July period.According to Ofgem, compared to the level between January and March 2025, the upcoming price cap is 1% or £20 lower. And year on year, adjusted for inflation, the new limit is 2%…
Scientists in Ghana have developed a device that combines a conventional solar-powered steam cooker with sand-based thermal energy storage. The system can achieve a thermal efficiency of 38.9% and has a payback period of 4.5 years. November 21, 2025 Lior Kahana A research group from Ghana has developed a solar-powered steam cooker (ISESC) with sand-based thermal energy storage (WKO). “The potential of sand, given its thermal stability and low cost, has not yet been extensively explored. Existing research mainly uses diodes, resistance heaters or induction systems as heat sources, with limited exploration of direct steam generation using stored heat in…
By Brad Kramer November 21, 2025 A community in Northern California has flipped the switch to a 5 MWdc solar energy + battery energy storage system that supplies power to a water treatment plant. The City of Vacaville held a “turn the switch” ceremony this week to celebrate the commissioning of the new facility at the Eastern Wastewater Treatment Plant (EWWTP). The solar energy and storage system is designed to offset the annual electricity demand of the EWWTP facility and will generate almost 8.1 million kWh of renewable electricity annually. The system increases overall energy efficiency while lowering utility bills,…
NextWave energy monitoring The solar industry has entered a new chapter, and the winners will be determined by an often overlooked piece of technology: solar energy monitoring. For years, monitoring was seen as a box to be checked on project checklists – a compliance item that faded into the background once a site went live. But that era is over: as the market matures and pressure increases, monitoring has become the backbone of project profitability. The solar energy sector is changing In the United States, developers and long-term asset owners are facing a new set of realities. Federal incentives that…
Unigrid is pursuing a contract manufacturing strategy for its sodium-ion batteries, using semiconductor foundry practices to shorten development times while shifting most production to underutilized Asian factories. November 21, 2025 Phoebe Skok By ESS news The battery industry has long been chasing the gigafactory model. Yet many of the most successful technological innovations and industries have achieved their success using a very different idea: outsourcing production to proven manufacturers. The semiconductor industry in particular has embraced the foundry model, where companies specialize in design (also known as a ‘fabless’ approach) or manufacturing and outsource the other element. It allows companies…
Sungrow signed new and renewed distribution agreements with Raystech Group, Supply Partners and Tradezone at the All-Energy Australia 2025 exhibition, covering solar inverters, battery energy storage systems and multi-year module supply for residential, commercial and utility markets. November 21, 2025 pv magazine By pv magazine Australia Chinese solar inverter supplier Sungrow, which has installed 870 GW of power electronic inverters worldwide, signed agreements with Australian renewable energy distributors Raystech Group, Supply Partners and Tradezone during a formal signing ceremony at the 2025 All-Energy Australia trade show in October. A new distribution agreement has been signed with Brisbane-based wholesaler Raystech Group,…
The company’s demonstration center in Dallas, Texas, is showcasing the steam-generating Arcturus heat pump, which it claims is eight times more efficient than natural gas boilers and six times more efficient than electric boilers and thermal energy storage. November 21, 2025 Patrick Jowett Texas-based Skyven Technologies has commissioned its Arcturus steam-generating heat pump (SGHP) demonstration project. The facility, which operates in Dallas, Texas, can provide 1 MWth of boiler-quality steam generated by capturing waste heat. It showcases the company’s end-to-end process, starting from recovering and upcycling industrial heat to generating boiler-quality, emission-free steam. The system features multi-stage flash technology via…
The Ohio House of Representatives has voted in favor of a bipartisan bill that would allow community energy programs in the state, including solar energy. The legislation cleared the House Public Utilities Committee 20-0 before passing the full House with broad bipartisan support, with a final vote of 73-2 in favor of the bill. House Bill 303 – the Community Energy Act – would allow Ohioans to subscribe to small, locally developed community energy projects and in return receive energy bill credits. These projects are privately financed, built close to where electricity is consumed, and relieve the grid during peak…
