Searching The Energy Saving Way

Now, I’ve no idea how true this is, it would be good to hear your comments.

When your screen is white, be it an empty word page, or the Google homepage, your computer consumes 74 watts, and when its black it consumes only 59 watts. Mark Ontkush wrote an article about the energy saving that would be achieved if Google had a black screen, taking in account the huge number of page views, according to his calculations, 750 mega watts/hour per year would be saved.


In a response to this article Heap Media created a black version of Google, called Blackle, with the exact same functions as the white version, but with a lower energy consumption.

As I said, I’m not so sure about this, are the savings too minimal? The fact the site is a custom search that has the potential to earn the owner money makes me wary, although of course you can be green and make money! Any thoughts?

  1. Hi,

    This actually makes sense…the black screen using less energy…and inturn emitting less co2.
    More than the money saved is the fact that you stay in a healthier surroundings for most of your day.
