Blackle…Making Google the Man in Black…

Did you know that you can browse google without wasting as much energy and at the same time have a classy google web page that makes you feel sort of like an ecofriendly vampire?

Well you can. Just click blackle.com or earthle.com to check it out. And, incidentally, read why ROTD’s colour codes are also ecofriendly…

Some history on blackle.com from treehugger.com:

A few months ago, TreeHugger Mark Ontkush wrote a post on his blog EcoIron “titled Black Google Would Save 750 Megawatt-hours a Year.” The post lays out the following train of thought. “An all white web page uses about 74 watts to display, while an all black page uses only 59 watts.” Google, which has a white background and gets about “200 million queries a day” could reduce global energy use by 750 Megawatt-hours a year by simply changing the color of its homepage to black.

In response to this post a black version of Google emerged called Blackle.com. According to Blackle’s homepage at publication time, 4,408.917 Watt hours have been saved by. The site encourages users to “make a difference today [by] … Blackling “energy saving tips” or visit[ing] treehugger.com a great blog dedicated to environmental awareness.” Nice ideas. But how does the search measure up? Very well indeed. Give it a whirl yourself and start saving energy one search at a time. :: Blackle.com

Here’s the original Mark Ontkush post from ecoiron.com :

As noted, an all white web page uses about 74 watts to display, while an all black page uses only 59 watts. I thought I would do a little math and see what could be saved by moving a high volume site to the black format.

Take at look at Google, who gets about 200 million queries a day. Let’s assume each query is displayed for about 10 seconds; that means Google is running for about 550,000 hours every day on some desktop. Assuming that users run Google in full screen mode, the shift to a black background will save a total of 15 (74-59) watts. That turns into a global savings of 8.3 Megawatt-hours per day, or about 3000 Megawatt-hours a year. Now take into account that about 25 percent of the monitors in the world are CRTs, and at 10 cents a kilowatt-hour, that’s $75,000, a goodly amount of energy and dollars for changing a few color codes.

I admit that I chose dark colours for ROTD because I felt like it and not because I knew it was ecofriendly but I suppose its nice to discover you’re an accidental environmentalist in some minute way…I could use a little good karma. And on that note……I leave you with the immortal words of that Southern bard…Johny Cash on why its more ethical to wear black.
I give you “The Man in Black”:

which makes one wonder…on the subject of colour coding…if black is the colour of “good” environmentalism then I suppose white becomes “evil” extravagance…but that is so boring. Couldn’t we nominate a more interesting colour for evil? How about pink?
