Buildings in Rizhao, a coastal city of nearly three million on the Shandong Peninsula in northern China, have a common yet unique appearance: most rooftops and walls are covered with small panels. They are solar heat collectors.

In Rizhao City, which means City of Sunshine in Chinese, 99 percent of households in the central districts use solar water heaters, and most traffic signals, street and park lights are powered by photovoltaic (PV) solar cells. In the suburbs and villages, more than 30 percent of households use solar water heaters, and over 6,000 households have solar cooking facilities. More than 60,000 greenhouses are heated by solar panels, reducing overhead costs for farmers in nearby areas.

In total, the city has over a half-million square meters of solar water heating panels, the equivalent of about 0.5 megawatts of electric water heaters.

The fact that Rizhao is a small, ordinary Chinese city with per capita incomes even lower than in most other cities in the region makes the story even more remarkable. The achievement was the result of an unusual convergence of three key factors: a government policy that encourages solar energy use and financially supports research and development, local solar panel industries that seized the opportunity and improved their products, and the strong political will of the city's leadership to adopt it.
