Plug-in panels are getting popular--how do we make sure they're safe? Dozens of US states are considering legislation to allow people to install plug-in solar systems, often called balcony solar. These small arrays require little to no setup and could help cut emissions and power bills. Balcony solar is already popular in Europe, and proponents say that the systems could make solar power more accessible for more people in the US, including renters. As popularity rises, though, some experts caution that there are safety concerns with how balcony solar would work with existing electrical equipment in homes. Let's talk about what balcony solar is, why it's unique, and how new testing requirements could affect our progress toward deploying the technology in the US.

When you purchase through links in our articles, we may earn a small commission. Aiper's EcoSurfer 2 is a skimmer on the slow side, but it makes up for speed shortcomings with outstanding longevity. Aiper's EcoSurfer 2 is a skimmer on the slow side, but it makes up for speed shortcomings with outstanding longevity. Roving pool surface skimmers are a surprisingly consistent category in the aquatic robotics space, typically featuring solar-powered, fully autonomous operation that you can drop in the pool and forget about for weeks. With its EcoSurfer S2, Aiper refreshes its skimmer design, boosts battery life, and improves intelligence. And while most pool owners can probably get by without a surface skimmer, it's a strong candidate for purchase if the surface of your pool is prone to collecting a lot of floating debris.

Missing values are common in photovoltaic (PV) power data, yet the uncertainty they induce is not propagated into predictive distributions. We develop a framework that incorporates missing-data uncertainty into short-term PV forecasting by combining stochastic multiple imputation with Rubin's rule. The approach is model-agnostic and can be integrated with standard machine-learning predictors. Empirical results show that ignoring missing-data uncertainty leads to overly narrow prediction intervals. Accounting for this uncertainty improves interval calibration while maintaining comparable point prediction accuracy. These results demonstrate the importance of propagating imputation uncertainty in data-driven PV forecasting.

California-based startup, Reflect Orbital, is poised to secure permission to launch a 60-foot (18.3-metre) prototype mirror into orbit to beam sunlight back to the Earth's surface. Once it has reached an altitude of 400 miles (640 km), the mirror will unfurl and illuminate a patch of Earth about three miles (4.8 km) wide. Someone looking up from the ground would see a small dot of light about as bright as the moon. Reflect Orbital says its space mirrors could allow solar power plants to operate 24 hours a day, provide lighting for disaster-struck regions, and even replace street lights.

As AI drives extraordinary power demands, energy intelligence is rapidly becoming a core business metric. Loudoun County, Virginia, once known for its pastoral scenery and proximity to Washington, DC, has earned a more modern reputation in recent years: The area has the highest concentration of data centers on the planet. Ten years ago, these facilities powered email and e-commerce. Today, thanks to the meteoric rise in demand for AI-infused everything, local utility Dominion Energy is working hard to keep pace with surging power demands. The pressure is so acute that Dulles International Airport is constructing the largest airport solar installation in the country, a highly visible bid to bolster the region's power mix. Data center campuses like Loudoun's are cropping up across the country to accommodate an insatiable appetite for AI.

Could AI Data Centers Be Moved to Outer Space? Massive data centers for generative AI are bad for the Earth. Data centers are being built at a frantic pace all over the world, driven by the AI boom. These facilities consume staggering amounts of electricity. By 2028, AI servers alone may use as much energy as 22 percent of US households.

Oshen's robotic sailboats are powered by the wind and the sun The UK's Royal Navy may return to the age of sail, with a new demonstration involving a flotilla of small, wind-propelled robot boats. Made by Oshen in Plymouth, UK, the vessels, known as C-Stars, are just 1.2 metres long and weigh around 40 kilos. Solar panels power navigation, communications and sensors, while a sail provides propulsion. Deployed as a constellation, the small vessels act as a wide-area sensor network. How the US military wants to use the world's largest aircraft "The simplest way of describing C-Stars is as self-deploying, station-keeping ocean buoys," says Oshen CEO Anahita Laverack .
