Ready for something super easy and free to do that will save energy? Meet Blackle, a Google search page that is black and therefore uses far less energy. According to ecoIron (a green IT firm), an all white web page uses about 74 watts to display, while an all black page uses only 59 watts. ecoIron then did a little match to see what kind of savings we'd accrue by using Blackle vs regular old Google:
Google gets about 200+ million queries a day. Assuming each query is displayed for about 10 seconds, Google is running for approximately 550,000 hours every day all over the world. Assuming that each user runs Google in full screen mode, the shift to a black background (on a CRT monitor...aka not a flatscreen) will save a total of 15 watts per view per person. That turns into a global savings of 8.3 megawatt-hours per day (8,300,000 watts/day), or about 3000 megawatt-hours per year. Now, taking into account that about 25 percent of the monitors in the world are CRTs, at $0.10 a kilowatt-hour, that's $75,000 per year, not too shabby for changing a few color codes on a single website.

Your redesign is nice Dale! I'm sure Kermit approves. I chose green for my "island" profile page for a variety of reasons.
ReplyDeleteThe problem with a black screen is it is much harder on the eyes...esp older eyes...that's why I changed my blog from black to navy borders and cream since it is very text intensive and my old theme was even giving me a headache!
