Incandescent lightbulbs banned

Incandescent lightbulbs are now banned across the entire European Union as of September 1. "Concerns about poor performance of replacement bulbs have been proved wrong." It is predicted to save 39 terawatt-hours of electricity across the EU annually by 2020. "The phase-out has been very smooth." BanTheBulb said "..the vast majority of the public have adjusted to using the next generation of lighting technologies with the absolute minimum of fuss and drama." [more inside]

Dark Skies Awareness

Time to turn off the lights. "Cities needlessly shine billions of dollars directly into the sky each year and, as a result, a fifth of the world's population cannot see the Milky Way. Malcolm Smith explains why a dark sky has much to offer everyone." [Via]

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.
