Why is this page black?
 

The Pretog is a black background alternative search site, and our objective is TO REDUCE THE TENSION AND THE DAMAGE CAUSED TO THE EYES because of luminosity excess projected by white background sites and TO REDUCE THE WASTE OF ENERGY to make searches. For the best understanding, read the text below.

Do you know?

  • To display an all white page, your computer uses about 74 watts, but to display an all black page it uses about 59 watts.

  • The luminosity excess projected by white pages is much more harmful to the eyes than black pages.

Isn't it interesting? Now, imagine the amount of energy saved if Google had black screen. Therefore we are to place in the web the black version of Google - the Pretog.

In his blog (EcoIron), Mark Ontkus made the calculations of this save, he assume each query is displayed for about 10 seconds, and concluded that this change would save 750 megawatts-hour (mWh) per year!
