Solar met 61% of U.S. electricity demand growth in 2025 as battery surge transforms the grid
A record-breaking year for solar generation and a leap in battery capacity have shifted the U.S. energy landscape, turning solar into a primary workhorse for meeting the nation’s surging power needs.
New York study finds distributed solar and storage could save ratepayers $1 billion annually
The report suggests expanding 2035 targets for local clean energy to 20 GW to mitigate wholesale price volatility and improve winter reliability.
MGM Resorts achieves 100% daytime solar power on Las Vegas strip
Output from Estuary Power’s recently-completed Escape Solar and Storage project more than doubles MGM’s share of solar energy.
What it’s like to build grid-scale batteries in Texas versus California
While both markets face ancillary market saturation, it has very different consequences in CAISO than in ERCOT.
Global solar corporate funding reached $22.2 billion in 2025
While global solar corporate funding in 2025 fell to the lowest level recorded since 2020, deal count rose to its highest level since 2017. Mercom Capital Group says investors favored smaller, lower-risk, execution-ready projects last year amid policy uncertainty, trade pressures and higher financing costs.
New design specifications for sodium-ion batteries
U.S. scientists used density functional theory to reveal how sodium ions are stored in nanoporous carbon anodes for sodium-ion batteries, identifying dual ionic and metallic storage mechanisms within the pores. Their findings provide practical design guidelines to improve battery voltage, safety, and commercial viability for stationary energy storage.
Duke Energy Florida unveils green hydrogen demonstration facility
The facility will use solar power to generate hydrogen used to run a modified GE Vernova combustion turbine during times of peak grid demand.
First Solar wins key round in TOPCon patent dispute
The federal patent office rejected separate challenges from JinkoSolar, Canadian Solar and Mundra Solar to invalidate intellectual property that First Solar claims is fundamental to the manufacturing of crystalline silicon solar cells.
Duke Energy commissions 50 MW battery storage project at former coal site
The utility activated a four-hour duration lithium-ion system at its retired Allen Steam Station to manage rising solar capacity and provide grid reliability in the Carolinas.
Solar to surge 49% as EIA forecasts 70 GW of new capacity by 2027
Utility-scale solar is set to meet rising data center demand as generation in Texas nearly doubles and battery storage capacity in ERCOT more than triples by 2027.
