China--the solar water heating capital of the world

My friends at China's Green Beat did a podcast (click image on right) on solar thermal heating last month. According to the self-dubbed "Green Brothers" of China's Green Beat, China has 40 million solar water heating systems covering 90 million square meters and accounting for two-thirds of the world's market share. The Chinese government intends to more than triple such surface area to 300 million square meters by 2020. The podcast takes a closer look at the city of Rizhao (日照)(which literally means "sunshine") in the northeast province of Shandong, the producer of 15% of China's solar water heating systems. According to Worldchanging, solar water heaters are currently installed in 99% of all buildings in Rizhao’s urban area, and in more than 30% of residences in rural areas.

Often mentioned in the same breath as Rizhao is the city of Kunming in the southern province of Yunnan, as this Worldwatch Institute story describes.
