“Since a white web page uses about 74 watts to display, while a black page uses only 59 watts; saving of 15 watts of energy can be done by a simple change of colour from the light background to a dark one. Google for instance, gets over 200 million queries a day. According to Mark Ontkush a black Google page saves approximately 750 Megawatt-hours a year. Hence, Heap media started the blackle.com utilizing this concept of energy consumption.”, Visual Voltage Project.

Therefore, I invite you all to use black backgrounds for your screens, websites, and maybe emails as well! If you have a Google email you could do that through the settings.
