Go Black!

I first heard this when a colleague/friend of mine told me about how much power we could save by using 'Blackle' instead of 'Google'. There's a lot of material out there, so I ain't gonna type the whole thing again.

Blackle saves energy because the screen is predominantly black. "Image displayed is primarily a function of the user's color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen." Roberson et al, 2002

In January 2007 a blog post titled Black Google Would Save 750 Megawatt-hours a Year proposed the theory that a black version of the Google search engine would save a fair bit of energy due to the popularity of the search engine. Since then there has been skepticism about the significance of the energy savings that can be achieved and the cost in terms of readability of black web pages.

Go Blackle. Guess it takes a little bit of getting used to it - and tackling your impulse, but I guess it's worth it.

"Have u used it atleast for a few day... Because when i used it, i felt like it may trigger a headache.. Also if u use LCD-TFT monitors, the black colour does not matter..

Same here.. White is more pleasant.. And black screws up your eyesight when you shuffle between sites because the general color is all white..

Hmm. Fair enough. I too tried a little bit, but it's hard to beat the Google impulse, particularly when the savings or whatever seems to be too insignificant from an individuals perspective. I guess I've already given up. :-P

You might want to note that blackle is just the homepage of www.searchincolor.com, which has offered web search in different colors since a much longer time. In general, all dark backgrounds on light text are energy saving-less illumination of the CRT-less pixel activation.

My favorite on searchincolor.com is the white background with green links-although not energy saving-it is really better for the eyes.
