If there ever was a disruptive technology, light-emitting diodes (LEDs) certainly fit the bill. They are slowly but surely taking over more and more lighting applications, from cell phones and signs to street lamps and indoor lighting. Only in recent years, though, have LEDs that produce white light come into their own. Since LEDs are semiconductors, they are still climbing a technology curve that will make them brighter, cheaper, and more energy-efficient. One day, they may even replace the lowly light bulb. And that would be a good thing, snce lighting consumes about 22 percent of all of our energy.
In this week's episode of The New Disruptors, I visit John Edmond and John Palmour, the co-founders of LED-maker Cree in Raleigh, NC (see earlier post here) to find out how far these little lights can go. I also talk to the mayor of Raleigh, which is replacing all of its outdoor municipal lighting with LEDs to save on the city's energy bills (Toronto is following suit). Watch the video.
