Cheaper L.E.D. bulbs may encourage more energy use

renewableenergywade writes: Light-emitting diodes (L.E.D.) devices are often touted as a greener, more cost-effective alternative to light bulbs, but a study from Sandia National Laboratories suggests that these devices are unlikely to decrease the world’s energy consumption.

Jeff Tsao and Jerry Simmons, researchers at the laboratories, pointed out that L.E.D.’s might even encourage more use of energy, rather than promote energy efficiency.
