According to a new study led by a team at Duke University, airborne particulate matter and dust are cutting solar photovoltaic energy output by more than 25% in certain parts of the world, with roughly equal contributions from ambient PM and PM deposited on photovoltaic surfaces.

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution. Their paper appears in the ACS journal Environmental Science & Technology.

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The University of Bremen is the scientific base of the international project known as EMeRGe (Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scales).

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. The proposal calls for what’s known as “solar geoengineering”: cooling the planet by deflecting sunlight that would otherwise strike the planet. There were nearly 40 million such flights in 2019.
