The phase-out of incandescent light is to begin with the 100-watt bulb in 2012 and end in 2014 with the 40-watt.
All light bulbs must use 25 percent to 30 percent less 2014. By 2020, bulbs must be 70 percent more efficient than they are today.

Apparently, it's time to ban Edison's venerable, now vilified, light bulb. European leaders, green pundits and the widely reported light bulb provisions of the U.S. Energy Independence and Security Act of 2007 all urgently push the abandonment of incandescent bulbs.
The plan appears to be to convince everyone to switch to compact fluorescent lights (CFL), a technology that was introduced in the 1930s and perfected when rock was young and computers used vacuum tubes.
What irony. Here we are, in the 21st century, with a semiconductor revolution in lighting around the corner. Semiconductor light emitting diodes (LEDs) are finally on the verge of having the capability to radically alter the entire lighting landscape with staggering improvements in both lighting efficiency and efficacy.
The high-power LED emerges directly from the same semiconductor, digital infrastructure and intellectual property that brought us iPhones, laptops, hybrid cars and Xboxes. Though the word "revolution" has been devalued by overuse, the LED is only the third revolution in illumination technology since the dawn of fire.

LED Solid State Lighting and Other High Efficiency Lighting Technologies for Commercial, Industrial, and Outdoor Stationary Applications
As energy efficiency becomes increasingly important for controlling costs, improving
energy independence, and reducing environmental impacts, governments and organizations have looked to lighting as the "low hanging fruit"
of energy efficiency.

Although electricity is a clean and relatively safe form of energy to use, there are environmental impacts associated with the production and transmission of electricity. Nearly all types of electric power plants have some impacts or effects on the environment, some more than others.

“LED lighting will reach an inflection point in the next
five years,” says managing director Clint Wheelock.
“As solid state lighting costs come down and performance increases, LEDs will become a practical option for an increasing number of commercial applications.”
During this period of transition, fluorescent T8 and T5 lamps, which offer good efficacy and life at very reasonable prices . . .

Why are the world's governments bothering? Why are they jetting to Cancun next week to discuss what to do now about global warming? The vogue has passed. The fad has faded. Global warming is yesterday's apocalypse.
Didn't somebody leak an email that showed it was all made up? Doesn't it sometimes snow in the winter? Didn't Al Gore get fat, or molest a masseur, or something?
Alas, the biosphere doesn't read Vogue. Nobody thought to tell it that global warming is so 2007. All it knows is three facts. 2010 is globally the hottest year since records began. 2010 is the year humanity's emissions of planet-warming gases reached its highest level ever.

A nurse holds a strange-looking device, moving it slowly toward a young patient's face. The note-card-sized device is covered with glowing red lights, but as it comes closer, the youngster shows no fear. He's hopeful this painless procedure using an array of lights will help ease or prevent some of the pain and discomfort associated with cancer treatment.
