Turn off the lights when you leave.

The end of the light bulb? E. Fred Schubert, a professor at Rensselaer Polytechnic Institute "claims to have invented a 99-percent efficient reflector that promises to speed the replacement of light bulbs with LEDs." According to researchers, this could happen within the next five years. The current prototype is bankrolled by the ARPA and The National Science Foundation "recently award Schubert's team a $210,000 grant to create in three years a commercial version of his patented omnidirectional reflector."

"Schubert claimed that lighting accounts for 25 percent of U.S. electrical energy consumption. Since white LEDs emit more light per dollar and generate less unwanted heat, they are potentially a major energy saver."

Meanwhile, some of the oldtimers seem to be pretty refractory.
