Baxi launches mid-temperature heat pump for commercial buildings
The UK-based manufacturer said its new air-to-water Auriga heat pump features a seasonal coefficient of performance (SCOP) ranging from 3.33 to 4.83 and noise levels of 43 dBA to 65 dBA.
Data center power loads threaten corporate net-zero goals
The world’s reliance on the internet, the shift to cloud computing, and the emergence of AI all fuel demand for more and more data centers. The International Energy Agency (IEA) projects that by 2026, data centers will consume more than 800 TWh annually, more than double their consumption in 2022. Tristan Rayner takes a look at the role that renewable generation plays in powering a digital world.
Year-to-year solar variability peaks in Europe, Australia, Argentina, and China
In a new weekly update for pv magazine, Solcast, a DNV company, reports that the regions with the highest year-to-year variability in irradiance include Central and Northern Europe, East Coast Australia, Northern Argentina, and China, with Africa exhibiting the most stable irradiance year-on-year.
Researchers find agrivoltaics have LCOE of $0.039/kWh, 7-year payback time in India
Indian researchers have compared the performance of an agrivoltaic system to monofacial and bifacial rooftop PV systems, and have found that the agrivoltaics setup had a shorter payback time and lower levelized cost of energy. Their analysis of performance considered panel temperature, power output, land equivalent ratio, and reliability.
