You know how Blackle is suppose to save energy?

Not so, per the following comment left on my original Blackle post:

” If you use LCD monitor, you’ll end up wasting more energy by using Blackle. Not to mention that you’ll stress your eyes and suffer from eye problems. Blackle will save energy only for CRT displays (which . On an LCD monitor, it will waste more energy than normal Google. Almost all the modern monitors are LCD monitors, as CRT monitors are obsolete. The so-called “Save Energy” seems to be a ploy by Blackle to attract more traffic to their site, as they earn money for every search made on their site.”

    If you follow the original Blackle links to the pages that first proposed that CRTs used more enegy to display white than black, you will see that they actually tested it and measured the energy consumption. On the other hand, this guy is just guessing. In fact, some types of LCD use more energy “on” than “off” and for some it is the other way around. In any case, the energy used to hold the pixels at a particular position is so far out-classed by the energy that supplies the backlight as to make it irrelevant. The actual amount saved is dependent on the percentage of monitors that are CRTs and how long each one is actually displaying Google/Blackle each day, both of which are clearly speculative.

    LCD may be obsolete in the US, but CRTs are alive and well in the world I live and work in…

    Good points, Brian & Chris. Glad I’m not the one tasked with measuring these claims. I’ll stick w/ my default Google tool bar.

    Please visit this pdf:
    You are misinforming many people and I do not appreciate it. On page 19, you will find a chart that is contrary to the rumor you are spreading. I do agree, through, that Blackle is misinforming people and is citing information that it only presents in forms that aid its purpose.

    The Wall Street Journal seems to agree that Blackle doesn’t save much energy when used with LCDs
    “Steve Ryan, program manager for Energy Star’s power-management program, asked consulting firm Cadmus Group to run a quick test by loading Blackle, Google and the Web site of the New York Times (which is, like Google, mostly white on-screen) on two monitors — one CRT, one LCD — and connecting a power meter to both. “We found that the color on screen mattered very little to the energy color consumption of the LCD monitor,” said David Korn, principal at Cadmus, which specializes in energy and environment, and does work for the government. The changes were so slight as to be within the margin of error for the power meter.”

    Blackle is the first page of, a site which has offered web search in color since much longer. I also like red background and while links combination-don’t know if it is as energy saving, but seems to be better for my eyes….

    Some people may find it uncomfortable reading light text on a black background. They might find Greygle to be a better choice for them. It uses a grey background with dark text which they might find easier to read. This still allows for some energy savings while providing an easier reading experience.

    Blackle’s energy saving approach has some merit, but there are flaws in the practical application as many have pointed out.
    I am proposing something different to help reduce display power consumption, spend less time using the monitor while running Google searches. How? Continue reading.
    I have setup several Google Custom Search Engines on a website using Google Topic driven search technology and a method that links multiple search engines giving me the ability to combine everything into one search engine.
    My approach is to use Google topics and categories in my Google Custom Search Engines to group search results. Once you enter an initial search string in the search box, the topics are displayed below the search box. When you select a topic the search combines the previous search string with the search string I have placed inside the topic.
    It works quite well and reduces the time you spend running searches.
    I have three main searches to choose from. The Plasma TV Custom Search makes extensive use of topics.
    Plasma TV Custom Search
    Music Custom Search
    Google Search
    Take a look and let me know what you think.

    The idea is simple : do your search in green, it will remember you that nature is important. Simple.

    Why doesnt have a images search?

  12. #12 by Alan on September 23, 2007 - 2:53 am

    It doesn’t have image search because Adsense for search doesn’t support image searches.
    My daughter has started using because she likes the very Pink color scheme. Personally I’m fine with plain white google.

    I’m fine with plain white google so to save energy I use

    Let’s remember that the Internet itself is said to consume about 868 billion kWh (kilowatt hours) of electricity per year to run the Internet, associated PCs, routing infrastructure, and phone networks.” (
    But companies are stepping forward with solutions to reduce the energy use of the Internet. Solar Energy Host ( for example, is hosting websites using 100% solar energy.

    hows about you all just let blackle do what it does.
    what would you do to bring attention to your site.
    So it provided a little false info. at least it looks good. They went out there and did something different, thats all it accounts for.
    As for the Pinkle Website. Its ugly as. As is the Greyle site.
    Honeslty. Dont discriminate it. If you like it, Use it.
    If you Dont like it, then dont use it. Cant get any simpler.
    People do things for a reason, let them be happy with their achievement, even if you dont agree.
    And as for the statement about it causing eye problems, im uhh pretty sure the bright white site is a bit more harsh.
    Whatever. Shut up and play nice

    blackle sucks

  19. #19 by casey on January 3, 2008 - 6:45 am

    I’m using at the moment , which is similar to blackle but offers a lot more functionality like image search, youtube search, mail access, etc. And looks nicer too, give it a try!
    bye 😉

    I use which is similar to greenle but it saves more energy. It is hosted on a server that is powered by wind and sun energy. Black search engines do not save energy as they claim and also my eyes twitch after seeing that black background.
