Developments in European renewable energy and social welfare include advancements in solar thermal technology and urban cooling solutions. At ETH Zürich, researchers have developed a solar thermal collector prototype capable of reaching 150 degrees Celsius to provide industrial process heat as an alternative to natural gas.

In Austria, researchers at TU Graz have produced 3D-printed porous ceramic cubes for passive urban cooling through evaporation. Additionally, humanitarian efforts continue in Germany, where the Christusgemeinde Wildeshausen hosted a summer camp for 29 Ukrainian children from Kyiv to provide respite from the war.
