Blackle

2007_07_26 blackle.jpg

In the name of energy conservation, Google is powering a search engine by the name of Blackle. It has been shown that for a given monitor, the energy required to drive a screen displaying light images is greater than that of one displaying a black image. On your own, the energy savings from using Blackle are small, but multiplied by the number of Google users worldwide the effects are substantial. Based on the average number of queries received by Google on a daily basis, the result is a global savings of 8.3 Megawatt-hours a day.

This doesn't really make much sense.

First, the description makes it sounds as though this is Google's idea. Blackle is a completely separate company that just happens to use Google. Google isn't really endorsing this.

Second, if you're using an LCD monitor, there aren't significant energy savings.

Third, the cost of talking to Blackle's servers, and then calling out and talking to Google's servers, and then replying and sending info to Blackle, and then Blackle pushing that info back to you takes more energy. They have to run a whole separate set of servers to run this, and that probably uses a lot more energy.

Also, reading white on black increases your eye strain substantially, so you're trading the possibility of incremental energy savings for the near certainty of additional health problems, including headaches.

While I'm keen on black, for some reason that just makes me think it's an angsty teen search engine.

Ya, actually - I just bought a Kill-A-Watt and have been going crazy measuring everything. With my Dell 17" LCDs there's no difference* between a totally white screen and a totally black screen.

* I think the resolution on the Kill-A-Watt only goes down as low as a single watt, so it could be different in the range of milliwatts.

Hmm. I was wondering, thought it could be a good idea (not a tech-savvy girl, me) and couldn't figure out why it didn't have all the nice functions that Google has. That explains it.

There are around 25 different versions of “black google” online. The best one I’ve found is www.cleanblack.com. Cleanblack is the only version that allows you to change the text colors of the google search results. Try it yourself by going to www.cleanblack.com/theme/
