After a year-long demonstration project, the U.S. Navy is poised add its own contribution to reducing the military’s carbon bootprint - or carbon wake, as the case may be. The Navy stands to gain up to 87% in savings for shipboard lighting, by switching from conventional light bulbs to high efficiency LED and HID systems developed through DARPA under the HEDLight (High Efficiency Distributed Lighting) program. One recent retrofit has been accomplished by Ohio-based Energy Focus, Inc. Saving energy is just part of the picture: the quantum leap to HEDLight is also expected to yield significant gains in the Navy’s strategic efficiency.

EU energy ministers meeting in Luxembourg gave final approval to an EU-wide ban on incandescent light bulbs. The switch to energy-saving bulbs was approved in advance of a meeting of European heads of state, held next week.

Several weeks ago, Venezuela President Hugo Chávez provided free energy-saving light bulbs to some low-income residents of Houston, Texas. This magnanimous act probably gained him a few American fans. In late March of this year, he also announced his plan to fund “an energy revolution” in Venezuela.
The revolution has an emphasis on using Venezuelan produced products like PVC pipes to construct homes. Another major component of the revolution includes an initiative to make Venezuela more self-sufficient in food production, thus quelling the need to import food. Projects to provide additional electrical power through alternative energies like wind and solar technologies are also commencing.
The most notable and measurable success to date for the so-called energy revolution, however, has been Venezuela’s effort to change out standard light bulbs across the country for CFLS (energy-saving compact flourescent light bulbs) exactly like those Chávez donated to Texans. So far, 72.3 million light bulbs have been changed. But the story is perhaps not as simple as it would seem (as is almost any story about Chávez and his schemes).

At night, South Korea is literally aglow. When the sun goes down you’ll find a vibrant night life of kareoke (”norebang”), street markets, and sujo bars. Still, per person, Koreans use only a little over half the energy used in the United States. How do they manage to light up the night–every night–and still save energy?
Part of the answer might be South Korea’s high usage of compact fluorescent light bulbs (CFLs).
It took me almost two months of living in Korea before I saw my first incandescent (”old fashioned”) light bulb. All of the others were energy efficient CFLs, like the one pictured here at this outdoor market.

I’ve been a a fitness and wellness professional for 18 years and I believe that tools we employ to improve personal health can also be employed for planetary health. Measuring progress through fitness assessment and “proving” that actions are producing results is huge motivator. Seeing empiricle data can help solidify new habits.
Although I am a right-brain, creative type, I enjoy measuring results as much as the next person. This past year, It seemed like everywhere I went, someone was handing me a Compact Fluorescent Light Bulb (CFL) and explaining how this 15-second change will remove CO2 from the air and fight global warming. That is why I got a kick out of One Billion Bulbs.

Altough there are other sites that will calculate your savings if you switch to CFLs, One Billion Bulbs lets you form a group and measure the results of making the switch.

I re-watch Al Gore’s acceptance speech again and again – and I always choke back tears. I suppose I choke them back because I’m an Englishman – with that supposed stiff upper lip.
Massive change is his message. Though of course individual action is beneficial, action on a larger scale is what’s needed.
Political will.
Praise then goes to the Irish government who have decided on a complete ban of incandescent light bulbs as of 2009.
This ties in so strongly with Mr Gore’s speech where he demanded – and eloquently too – that change needs to happen.
Now.
Not beleagueredly in a few years.
But now.
So is my government concurrent with regards to light bulbs?
No.

Even if you’ve switched all your bulbs from incandescents to CFLs, it’s still good to practice turning off the lights when you don’t need them to save on energy.
Turning off the lights depends on the bulb. If you still have incandescent bulbs, it is always best to shut the light off when no one is in a room or if you aren’t using the light. Fluorescent lights are a little different, since constantly

Imagine growing up, going to school, graduating, going to college for a couple years and then getting that magical phone call: "Son, it's time to change the light bulb." You rush home in flurry of excitement and anticipation as your parents show you how to change a light — something you yourself may not do until your own kids are in college. Those times are coming.
Well actually, they're here. But until prices coming

Kenny Luna may have some help in his quest to get CFLs into the hands of students across the country: nine schools in Southern California. The schools are part of the Alliance to Save Energy's Green Schools program; elementary and high schools in the Alta Loma, Hesperia, and San Bernardino Unified School Districts are all participating
The schools provide students and their families a means to exchange incandescent bulbs with

CFL and incandescent bulbs side by side
Quality was spotty in the 70s, but this is a new millennium
Apple computers. Punk. Compact fluorescent light bulbs (CFLs). What do they have in common? They were introduced in the 1970s and are now back in style.
CFLs have improved dramatically from their inauspicious beginnings. They took a while to come on, flickered as they
