Well, I bet you’ve all heard about Google going black yesterday. The reason? The Earth Hour. Apparently, there’s enough evidence supporting the fact that White on Black websites consume less power on displays.
As noted, an all white web page uses about 74 watts to display, while an all black page uses only 59 watts, 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.
Then again, on the same Google’s Earth Hour Page they explain that the real reason behind the decision on going black is actually more of a publicity stunt than an actual conservation measure.
As to why we don’t do this permanently - it saves no energy; modern displays use the same amount of power.
Wheew, Thank God somebody came in and made everything crystal clear. No, wait, now I’m even more confused :/
