Solar PV led world energy demand growth in 2025, but the U.S. turned to fossil fuels, says IEA report
The International Energy Agency’s latest Global Energy Review shows solar PV accounted for 27% of all energy demand growth, while demand grew 62% faster in the U.S. than the world total, largely driven by a 10% increase in coal use, as the world enters what the report’s authors call the “Age of Electricity.”
Control, not capacity, could be the next driver of U.S. residential storage investment
Investors are shifting focus from deployment growth to platforms that can orchestrate and monetize battery fleets.
Cyber threats for PV: What are distributed denial-of-service attacks and how do they work
Denial-of-service attacks overwhelm networked systems with massive traffic from compromised devices, disrupting communication and making critical services like PV system monitoring and control unavailable. They can cause operational instability, reduced energy production, and safety risks, requiring layered defenses such as filtering, redundancy, and automated mitigation to maintain system resilience.
Span and Nvidia to develop AI data centers in your backyard, lowering electric bills
The two will develop XFRA, a distributed network of compute nodes connected to homes with smart panels, batteries and optional solar generation, in partnership with Nvidia and homebuilders like PulteGroup,
Managing cyber risks in the era of decentralized energy
The move toward decentralized energy resources offers resilience and flexibility in power generation, but it also introduces new complexities that demand proactive security measures.
The world added 4 GW of new solar capacity for every GW of wind in 2025, but wind is gaining
A new report from global energy think tank Ember shows 814 GWdc in new solar and wind capacity was installed in 2025, but the pace of wind deployment rose 47% year-over-year compared to just 11% for solar.
Most state-permitted U.S. solar and wind projects in 19 states received a timely permit
In 19 states analyzed, permitting processes partially or fully adjudicated at the state level “are not preventing new potential energy from entering the grid,” researchers said.
SolarEdge outlines path to 800 V (DC) data center infrastructure
SolarEdge has outlined a transition pathway to integrated 800 V (DC) infrastructure for data centers, arguing that legacy alternating current (AC) systems introduce inefficiencies that could constrain the growth of AI workloads. It says rising compute demand and next-gen NVIDIA GPUs are increasing urgency, while data centers lose an estimated 10% to 30% of input power through multiple conversion stages.
National laboratories lead multi-agency push for solar cybersecurity standards
The Department of Energy is deploying a research framework across four national laboratories to harden the domestic power grid against digital vulnerabilities as solar deployment accelerates.
PJM states could lower electric bills by enabling retail choice with household batteries
As state governors across the PJM grid region “have expressed alarm over capacity prices” that drive up electric bills, retail choice models that can quickly deploy thousands of distributed batteries can make consumers “the primary source of new capacity,” says the author of a new report.
