Black and White Issue

Many of you will have read about the black screen google thing (Blackle). It started on the Eco Iron blog in January this year and a full report of the whole story can be read here This meme is spreading, for instance Clownfish now have a black screen website.

The net net is that sites displayed in black do use a lot less energy (between 18 and 88%) on CRT (cathode ray tube) screens. In case you arent sure, CRTs look like this

But 75% of screens are now LCD in case you arent sure they look like this. On LCD screens some studies suggest a black screen uses more energy.

So the question is this. how many readers of this blog use CRT vs LCD? Based on the answer we can take a rational decision. It is a one-click process to turn this into white type on a black background. It will be harder to read though, I suspect. so lets only do it if it makes sense given who uses what screen. So come on dont be shy, just click on the poll below and lets see what's the best thing to do.
