Rizhao is a prefecture-level city in southeastern Shandong province, People's Republic of China. Sitting on the coast of the Yellow Sea, facing Korea and Japan across the sea in the east. Rizhao borders Qingdao to the northeast, Weifang to the north, Linyi to the west and Lianyungang to the south. It is a major seaport.
A government program enabled 99 percent of households in the central districts to obtain solar water heaters, while most traffic signals and street and park lights are powered by solar cells, limiting the city’s carbon emissions and urban pollution. 
The city now mandates the incorporation of solar panels in all new buildings, and oversees the construction process to ensure the panels are correctly installed.
