Ever wonder what a world without light bulbs might look like? Terrapass has a window into the future:

Old-school incandescent light bulbs are going the way of the dodo -- already illegal in Europe and soon enough in the United States as well. Mostly CFLs will replace them in the near term, but as the price of LEDs drop, many expect them to become the bulb of choice. What comes after that?

Could be OLEDs:

Because OLED panels are just 0.07 of an inch thick and give off virtually no heat when lighted, one day architects will no longer need to leave space in ceilings for deep lighting fixtures, just as homeowners do not need a deep armoire for their television now that flat-panel TVs are common.

Within a year, manufacturers expect to sell the first OLED sheets that one day will illuminate large residential and commercial spaces. Eventually they will be as energy efficient and long-lasting as LED bulbs, they say.

Because of the diffuse, even light that OLEDs emit, they will supplement, rather than replace, other energy-efficient technologies, like LED, compact fluorescent and advanced incandescent bulbs that create light from a single small point.

The green movement is gaining traction, that's for sure!
