Blackle.com does not necessarily use less energy than Google.
Previously we’ve looked at situations where a supposed green alternative proves in practice to be more harmful to the environment than the problem it is replacing. Therefore we were interested to come across this post at green-blog.org discussing the potential fallacy of the website blackle.com. Blackle claims that because the background on Google’s search page is white, it burns more energy than the alternative that Blackle provides (a google search bar with an all black background).
However, apparently this energy savings only occurs with computers that use certain monitor types (CRT) and not with others (LCD). Since most modern computers use LCDs (the new thin models) instead of CRTs (the big boxy models), this “solution” may actually increase energy usage. Google agrees and weighs in with their own analysis here.
