Fascinating and useful data on the effects of light pollution on the environment is provided in this poster. Is your city one of the top 10 brightest cities in the world? In this particular case, “brightest” is definitely NOT a synonym for “smart.”

Interesting high-level view of light pollution issues and a good- start-point for discussion. “The Energy We Are Wasting” section should specify the time interval – are these annual numbers? The light fixture section could also discuss *types* of luminaires: HID, fluorescent, LED, etc.Selection of lamp type has a profound effect not only on light pollution, but on energy usage.

Valencia is clearly the brightest city on Europa, and Madrid is brighter than London.
