CFLs on a landscape scale

I listened to a NPR story today about upcoming legislation to encourage the switch from incandescent to compact fluorescent light bulbs. I'm looking forward to perceiving this switch from 30k feet. I noticed a few years ago that the nighttime lights of civilization were switching increasingly from yellow to white. Grids of pure white to blueish lights appear pretty futuristic in comparison to yellows reminiscent of oil lamps.

At least it's a more aesthetically pleasing form of light pollution...
