In announcing the award, the academy said, "Replacing light bulbs and fluorescent tubes with LEDs will lead to a drastic reduction of electricity requirements for lighting." The president of the Institute of Physics noted: "With 20 percent of the world's electricity used for lighting, it's been calculated that optimal use of LED lighting could reduce this to 4 percent."
The winners, Shuji Nakamura, an American, and Isamu Akasaki and Hiroshi Amano, both from Japan, justly deserve their Nobel, and should be commended for creating a technology that produces the same amount of light with less energy.
But it would be a mistake to assume that LEDs will significantly reduce overall energy consumption.
