LEDs: Not So Green After All?

Facebook X LinkedIn Email
ALBUQUERQUE, N.M., Sept. 7, 2010 — Solid-state lighting pioneers long have held that replacing the inefficient Edison light bulb with more efficient solid-state LEDs would lower electrical usage worldwide, not only decreasing the need for new power plants but even permitting some to be decommissioned. But, in a paper published Thursday in the Journal of Physics D, leading LED researchers from Sandia National Laboratories argue for a shift in that view. "Presented with the availability of cheaper light, humans may use more of it, as has happened over recent centuries with remarkable consistency following other...Read full article
