I’m a big AGW skeptic and didn’t much care for the carbon theme woven into this. But I AM a big proponent of eliminating energy waste. IMO, this event didn’t go anywhere near far enough.
Those cities should have simply turned off the streetlights. Actually, they should simply remove the stupid things from most residential neighborhoods and drastically lower the wattage in commercial and industrial areas. Scientific study on the subject shows the stupid things do more harm than good. They only reason they continue to get built is public sentiment (people don’t like the dark). People think they enhance safety and reduce crime, but they usually make both situations worse. The alternating pattern of glare/dark, glare/dark makes MORE shadows and hiding places for criminals than a consistent low glow from surrounding buildings would. The same issue makes it HARDER to see pedestrians and bicyclists (thus reducing safety).
If you live in a lit community, you paid about $1,000 more for your house because of it. Those useless lights are also most of the reason that suburbanites like myself can’t see more than a hundred or so stars on a clear night.
