"Black Google" with a black background rescues the earth

Various colors are used for web pages, but the power consumption seems to be different depending on the color to be displayed. For example, just as Google's background turns black, the power consumption going down is pretty. It seems that it is roughly $ 300,000 per year.

Is it true?

Details are as follows.

According to this article, it seems that the power consumption when displaying a web page with a white background is 74 W, 59 W if it is a black web page.

And thinking that Google is 200 million page views a day and is displayed for 10 seconds per search, it is 8.3 MWh per day for black and 3000 MWh per year compared to when the background is white It seems that power can be reduced. And thinking that the electricity charge per 1 kWh is 10 cents (12 yen), it saves electricity savings of 300 thousand dollars (equivalent to 36 million yen) per year.

If the power consumption when displaying a white web page is 74 W, it seems that yellow is 69 W, blue is 65 W, red is 65 W, purple is 61 W, black is 59 W.

By the way, although the background is black "Black Google", it seems that it will be this kana.

Additional notes

The above power consumption seems to be the power consumption on the CRT monitor. The unit of power consumption was wrong, so I fixed it.
