The second point about LCD monitors is particularly instructive because it highlights the human element that can foul up the best plans.<BR/><BR/>Graham: Thanks The <I>Sunday Times</I> appears to have been a big story for techies, <A HREF="http://www.technewsworld.com/story/Harvard-Prof-Sets-Record-Straight-on-Internet-Carbon-Study-65794.html" REL="nofollow">this article</A> being a fairly thorough one, including some relevant links, that also reflects unfavorably on the <I>ST</I>.Jun Okumurahttps://www.blogger.com/profile/00291478225274759649noreply@blogger.comtag:blogger.com,1999:blog-32776756.post-51577067872785297862009-02-02T00:16:00.000+09:002009-02-02T00:16:00.000+09:00Google search was flagging every non-Google web si...<I>Google search was flagging every non-Google web site and some of its own with the warning "This site may harm your computer"</I><BR/><BR/>Actually, they even flagged themselves, according to <A HREF="http://www.techcrunch.com/2009/01/31/google-flags-whole-internet-as-malware/" REL="nofollow">TechCrunch</A>'s screenshot.<BR/><BR/>On Google's power use implications, there's been some controversy...<BR/><BR/>http://www.infoworld.com/article/09/01/14/Harvard_academic_refutes_Google_carbon_footprint_story_1.htmlAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-32776756.post-26630845839885284112009-02-01T19:42:00.000+09:002009-02-01T19:42:00.000+09:00That savings idea is interesting to me since it's ...That savings idea is interesting to me since it's an example of old truths no longer holding as technology advances.<BR/><BR/>The idea is that a CRT monitor that paints an image needs to shoot a stronger beam the brighter the color, with no beam at all for pitch black. So a black screen with a little white text would use much less energy than a white screen with a little black text.<BR/><BR/>But CRT monitors are becoming rare today, supplanted by LCD monitors of various stripes. And they have an always-on light source that is blocked or not by the individual liquid crystal pockets on the screen surface. As the light source stays the same the energy use doesn't change at all.<BR/><BR/>And in fact, it may be worse - for LCD monitors, a white screen will in fact draw slightly less power than a black one. First, for some LCD technologies darkening a pixel draws energy while brightening it does not. Second, as a practical matter, when the screen is white and bright the users will tend to lower the screen brightness, and so reducing the power use of the backlight.Jan Morenhttps://www.blogger.com/profile/06834641501438709866noreply@blogger.com
