Did you know that a monitor requires more power to display a white (or light) screen than a black (or dark) screen?
O.k. so the savings aren’t huge (an all white web page uses about 74 watts to display and an all back page only 59) but apply this to Google, which gets at least 200 million queries per day, and the numbers start to become slightly more significant (see the blog post “Black Google Would Save 750 Megawatt Hours a Year”).
So, what can you do to help? Well, why not try using uk.blackle.com, a search engine powered by Google. By setting it as your homepage, every time you load your internet browser a little bit of energy will be saved!
