A Black Google Would Save 3,000 Megawatts a Year Globally !!!

a white web page uses about 74 watts to display, while an all black page uses only 59 watts... do a little math and see what could be saved by moving a high volume site to the black format...*i144.photobucket.com/albums/r168/happyandy/surprised.gif

Check out this Digg about Google.
A guy calculated something which is important to the whole world of computing *www.day.az/forum/style_emoticons/default/thinking.gif

From what it seems, an all-white web page uses about 74 watts to display, while an all-black page uses only 59 watts. Taking Google searchpage which gets about 200 million queries a day into account. Let's assume each query is displayed for about 10 seconds; that means Google is running for about 200000000*10/3600 = ~555,000 hours every day on some desktop in the world. 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.

Think of the power-savings if Google turned black!!!
Whatddya think?

What he did not calculate is the $$$ in terms of lost eyesight continuously staring at black screen with white letters.

well then tell that man to ask everyone to convert their pages to black ....majority of webpages are in white ....if they all are converted to black think how much power would be saved

If everybody stopped using the net, imagine how much power we could save. Even if google shuts down, that would save a lot of power. And whoever proposed this stupid idea, if he dies, imagine how much people would be saved from torture.

Moral of the story : Do some whacko calculations. Bask in the glory of a million page views.

Isn't Google saving enough power already by giving people accurate search results quickly?

BTW, another bit of info, power to keep it's servers up is one of Google's major expenses. Infact, I believe they recently got a whole lot of solar cell arrays to score some points as an environment friendly company.

Actually, every big organisation should do that. Why waste the millions of watt of power the sun is deleivering every day?

In fact if magazines start listening to requests by users and provide stuff in discs, that will save a lot of power. Not everyone will be needing to download same thing over and over again.

Making the switch from white to black pages is not the point here - that will never happen. Devices just have to be more efficient in terms of energy consumption.

Well, the reason for saving power is not justified for LCD screens. For LCD screens, it doesn't matter displaying black or white. Both consume same power!
