I spend most of my working hours these days helping organizations understand and improve their ability to innovate. A small niggling problem has arisen. For years, the standard image for the creation of ideas (I hate jargon like ideation) has been the incandescent light bulb. But now it’s also a symbol of inefficiency and wasted energy. The compact fluorescent has taken over my house, and it should take over many others.

Now I read that this may just be a blip. We should all move to LEDs. I have to read Brilliant: Shuji Nakamura and the Revolution in Lighting Technology to figure this one out.
