Deutsche Welle is examining whether green roofs can protect cities from deadly heatwaves. As urban temperatures climb with climate change, planted rooftops are being promoted as a way to cool buildings and streets, reduce energy use, and limit heat-related deaths. The report explores how vegetation on roofs lowers surface temperatures and whether cities can scale the idea fast enough to matter.

New research indicates that installing green roofs beneath or alongside solar panels can improve the panels' efficiency. Vegetation cools the roof surface, and since solar panels lose output as temperatures rise, the cooler microclimate helps them generate more electricity. The findings, highlighted by architecture and design media, are drawing attention as cities look for ways to combine climate adaptation with renewable energy on buildings.
