Research commissioned by the British government shows that rooftop solar panels can significantly influence fire behavior, especially when the height distance between the modules and the roof surface falls below critical limits. December 30, 2025 Patrick Jowett A research paper commissioned by the UK government has concluded that a more comprehensive approach to fire safety in rooftop solar installations is needed. The researchcarried out by Manchester-based fire and risk consultancy OFR Consultants, includes a literature review examining the extent to which rooftop solar systems alter fire dynamics or pose additional risks to roof structures and firefighting operations. It was found…

Buried in the reddish soil of southern China lies latent power: one of the largest clusters of crucial rare earth elements is being mined 24 hours a day by a secretive and heavily guarded industry. The hills of Jiangxi province are home to most of China’s rare earth mines. The materials are used in a wide range of products, including smartphones and missile guidance technology. The booming industry is closely protected by Chinese authorities and media access is rarely granted. During a rare visit to the region last month, AFP journalists were followed and tailed by minders who refused to…
