Blackle – Energy Saving Search: Every little bit helps. Right?

Blackle was created by Heap Media to remind us all of the need to take small steps in our everyday lives to save energy.

Blackle saves energy because the screen is predominantly black. “Image displayed is primarily a function of the user’s color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen.” […]



  1. LCD monitors use the same amount of power, regardless of how bright the image on the screen is. The difference in power consumption with other display types is tiny. However, it does raise the consciousness of net users, to save energy in other ways.

  2. does anyone else notice that whatever you search for, this treehugger site comes up in the top 10 almost every tme?

    want to save energy? put your computer to sleep and go ride a bike.

  3. While the idea of Blackle has some merit there are clearly some flaws.

    There are other ways to save power mainly, spending less time using the monitor while running Google searches.

    I have setup several Google Custom Search Engines on a website using Google Topic driven search technology.

    I create and group search results using categories that you can click on. Once you enter an initial search string in the search box the category selections are displayed below the search box.

    I also use a technique that links multiple search engines giving me the ability combine everything into one search.

    It works quite well and results in you spending less time running searches.

    Take a look and let me know what you think.

  4. This is in response to the recent posts on blackle which got under my skin a) because it isn’t really agreed on that it works and b) he’s actually making money from it, but it goes into his own pockets!!!

    Since it is is common knowledge that black pages in general don’t do anything productive, I would suggest as an alternative.

    I know it’s not the answer to everything, but unlike blackle etc who are making money from uneducated searchers, re-invests any profit back into environmental schemes in a bid to try and offset a small part of your web use.

  5. I’ve seen a few pages around which claim to help the environment in many ways, the main being – using a black screen energy consumption is reduced and therefore your “foot print” is reduced.

    Personally I feel the savings are minimal and we need to take an additional more proactive approach. using as a search portal does this. Any profits generated through searches on this site are actually reinvested into “green” projects such as forest regeneration. So in basic terms you are making positive changes to our world as you search. And the best this is – it costs you as a user – NOTHING!!

    If for nothing else, at least give it a try and get your friends to have a go as well. There’s nothing to loose, and a whole lot to gain.

  6. I don’t think that the case for human created global warming has been made yet. Millions of people seem to be jumping on the so-called green bandwagon. Yes the planet seems to be heating up (as it has done in the past) but is it conclusively proven that our (human) C02 emissions are the cause or the main cause. The terms, Global warming and man made global warming; two very different prospects often confuse people.

    If the man made bit does not hold up then money possibly could be better spent on trying to protect the people most in danger from the now, seemingly inevitable rise in temperature. It was not that long ago scientists were talking of the fear of a new ice age. With energy prices on the rise and ‘green’ pressures taking their toll on industry pushing costs up further it wont be long before this ‘green’ movement has pensioners and others in fuel poverty turning ‘blue’.

  7. Test conducted by Google itself has proven that Blackle may save little energy with CRT monitors but will actually increase energy consumption with LCD monitors.

    Because of this misconception, it has created a easy money making business for the creator of Blackle. It has been estimated by many SEOs that he should be pocketing over thousands of dollars each day from google ads.

    Also it is very obvious that Blackle is violating Google’s TOS and adsense policy, “Publishers are not permitted to make prominent use of ‘Google Brand Features’”.

    I personally think it is so unfair for other publishers that are putting huge amount of times and effort into writing quality contents for website to attract visitors and increase their income from adsense, while someone just violate the adsense policy and Google isn’t doing anything about it.

    If anyone agree with me and want to stop Blackle, then just visit Google’s adsense violation contact form and lodge your complaint about Blackle. STOP BLACKLE!
