Blackle - Environmentally friendly Google
ENGLISH VERSION
Whenever your PC screen is all white (as in a Word page for instance) the computer will consume about 74 watts. When black it uses an average of 59 watts. Using this knowledge, some months ago, Mark Ontkush wrote an article about how much could be economized if a Google page used a black background instead of white. Taking into account the enormous popularity of the site, according to Mark's calculations, about 750 megawatts/hour would be economized each year. Using this data Google created an all dark version of his search engine calling it Blackle that works exactly as the original version but consumes less power. http://www.blackle. com/

Hi all -
I've been bemused by this whole Blackle / Google discussion since it arose some time ago. I might have missed the comment if anyone has made it but the whole question of black screen versus white screen depends on which application you're using most of the day. If you're sitting in MS Word or Excel or an Internet browser, you're not going to get the slightest benefit from Blackle's screen. I'm a very frequent user of Google too, but just how much time do other people spend looking at the search results screen itself? I quickly move on to the target screens whose colours I have no control over. It's a little like having a beautiful background as your desktop wallpaper.. when do you get to see it? I see mine twice a day .. once as I power on and once as I shutdown.

That's a brilliant point, Lisha!
You looked beyond the "single part" of a person's computer use to see "the whole" of what's on someone's screen each day. Thanks for seeing how we use our computers from a whole system perspective. :-)
Take care,
Steve
Using Blackle rather than Google will save energy if your monitor is a CRT. Google, on the other hand, will save energy on LCD monitors smaller than 22 inches (diagonal). Blackle uses less energy on LCD monitors having 22 inches or greater, with rare exceptions. Test results at http://techlogg.com/index2.php?option=com_content&do_pdf=1&id=360
