Power-Saving Web Pages: Real Or Myth?

An anonymous reader writes "Are dark webdesigns an energy saving alternative to a snow white Google? The theory is websites with black backgrounds save energy, based on the assumption that a monitor requires more power to display a white screen than black. Is this a blatant green washing ploy by Blackle.com, or an earnest energy saving tweak for a search tool we use every day? To find out, PCSTATS hooked up an Extech Power Analyzer to a 19" CRT and a 19" LCD and measured power draw — turns out there is a not insignificant difference ..."

    "turns out there is a not insignificant difference "

    Double negatives are not not bad.

    If you wait a few seconds, your watts will turn into joules.

    Oh god. I was wondering why my screen randomly seems to increase/decrease in brightness.

    I hate this feature. It makes me think someone slipped me some acid, and then I'm disappointed, because no, it's just bad attempts at saving power.

    There is a not insignificant parsing complexity.

    This.

    It is obvious that black is good for the earth and white is bad.
    Why do you think we have climate change? Because of white, of course. No one has even heard of climate change before white messed everything up.

    Not only is white bad, white is unhip. What do you want at your disco? White lights? No, black lights produce the right mood.

    Let's fight the white and save the world!

    But the characters are black, so each one represents energy saved.

    No, the big power draw is from CRT displays.
    Both of them. They'll die someday and things will be nice and green again....

    Back in my day the CRTs were green... or sometimes amber.

    The only advantages of LCDs are size, weight and power consumption - all of these are not primary features of a monitor, at least for me (the same way that I don't buy a car based solely on the fuel consumption, or a computer based on its power consumption and size - I look for performance and cost first).

    The LCD advantage that I prefer? Not irradiating remaining eye.

    Set your background to black, and all your text so it only displays half the time.

    CRTs have big geometry problems...
    CRTs also take up so much space that is ridiculous.

    Is that not also a geometry problem?
