This morning, looking north out the window of the Green Lake View ( Cui Yi Hu*) hotel in Kunming, capital of Yunnan province in southern China:

Clue, in case you didn't spot it yourself: Every roof as far as you can see has solar-thermal panels for hot water heating. More to come shortly on China's general environmental/climate situation, but I think this vista is different from that in many US cities -- among other details you might notice, in the prevalence of the panels.

* Originally thought we'd stayed in the Green Lake, Cui Hu. On correction from higher authority, ie my wife, I realize it was the Green Lake View, Cui Yi.
