Blackle

[miffy63]

I received an email about Blackle recently but we can't figure out if it's a genuine search engine or not, if it really saves on electricity and if so how?
Am I being fooled?!

Blackle uses the Google search engine but displays results against a black background, instead of a white one. If you're using a CRT monitor, this will require less energy because the screen is black by default and it requires energy to turn it white. However, if you're using an LCD monitor, the pixels are naturally transparent and it requires slightly more energy to turn a pixel black than to turn it white.

So Blackle saves energy when used with CRT monitors but uses slightly more energy with LCD monitors.

PS: If you want to 'do good' with your choice of search engine, use MagicTaxi (which is a 'front end' for Yahoo!). The more users it has, the more it can get from advertising revenue which, in turn, means more money for the British Heart Foundation, Barnado's and other UK charities: http://www.magictaxi.co.uk
