Global Radiative Sky Cooling Potential Adjusted for Population Density and Cooling Demand

Thanks to recent advances in nanophotonics and scalable manufacturing of metamaterials, radiative sky cooling has emerged as a “self-reliant” cooling technology with various potential applications. However, not every region across the globe is well suited for the adoption of radiative cooling techno...
