Everyone here might be interested to learn that scientists at the University of Rochester have figured out how to turn old-style bulbs into super-efficient versions just by zapping them for a few seconds with a powerful laser.
That little laser zap creates an "array of nano- and micro-scale structures on the surface of [the] regular tungsten filament—the tiny wire inside a light bulb—and these structures make the tungsten become far more effective at radiating light."
They still need to perfect the technology, but soon enough they may not be the energy dinosaurs that they currently are (plus they'll be cheaper than CFLs and have no toxic mercury in them)!
