Radiative sky cooling (RSC) technology dissipates the terrestrial heat to the extremely cold outer space, without any energy input and any pollutant produced. It has the potential to simultaneously alleviate the two challenges of energy crisis and global warming. In this review, we look for the inspirations from the relatively mature solar thermal harvesting (STH) technology to solve the challenges in the RSC field. We firstly summarize the comparability and similarity of the two technologies from five levels: principles, materials and structures, devices, systems, and applications. Subsequently, the valuable inspirations or strategies from the STH technology are proposed to advance the development and application of the RSC technology. Finally, we discuss the application of the RSC technology to solve the challenges of water shortage and night lighting in remote areas, aim to broaden the application scope of this technology.
