Energy-Efficient LED Lightbulbs on the Horizon

Numerous researchers are trying to replace the current incandescent bulb with more energy-efficient solid-state lighting. D.D. Sarma, a materials scientist at the Indian Institute of Science, in Bangalore, has made tiny crystals of semiconductor material that, when coated onto a light-emitting diode (LED), give off a white glow just the right color for illuminating a living room. So far, it's only a weak light, but Sarma hopes to make it much brighter. Best part is, Sandia National Laboratory estimates that if half of all lighting is based on LEDs by 2025, the world would use 120 gigawatts less electricity, saving $100 billion a year and cutting the carbon-dioxide emissions from power plants by 350 megatons annually.
