RWE, Peak Energy to deploy first sodium-ion battery in US grid
Peak Energy says it will deploy the first sodium-ion battery in the Midcontinent Independent System Operator (MISO) service area with RWE Americas in eastern Wisconsin, using passively cooled grid-scale storage that cuts auxiliary power use by 90% and lowers lifetime storage costs by $70/kWh.
Increased spacing between solar module rows boosts agrivoltaics viability
U.S. researchers developed a framework showing that wider spacing between solar PV rows can make agrivoltaic systems economically viable for large-scale mechanized farming. Their simulations in Colorado demonstrated that optimized row spacing maintains crop production while improving combined agricultural and energy revenues.
US solar generation reaches 385 TWh in 2025 as power demand rises
US solar generation rose nearly 25% in 2025 to 385 TWh, but rising electricity demand meant fossil generation and overall emissions also increased.
Swift Solar acquires Meyer Burger assets to scale U.S. HJT and perovskite production

US solar installations reach 43 GW in 2025 despite slowdown
Solar accounted for 54% of new US generation capacity in 2025, retaining its position as the top technology for the fifth straight year, while PV and storage together made up 79% of new electrical capacity, according to the latest report from the Solar Energy Industries Association (SEIA) and Wood Mackenzie.
Setting the stage for US energy storage
Sweeping import tariffs and the One Big Beautiful Bill Act (OBBBA) made waves for the US clean energy industry in 2025. While solar developers chase safe-harbor deadlines, US energy storage manufacturing could benefit from rules encouraging onshoring – provided there is policy certainty to bank on
Beazley to acquire kWh Analytics to expand renewable underwriting
