In an effort to save the world or something, were all supposed to turn our lights off at 8pm, till 9pm. I dont think we have to turn our computers off though so just move the keyboard near the screen or something.
Google have turned their lights out, and when you think about it if everyone in the UK (and in some parts of Europe) turn their lights off at the same time it would probably save enough energy to power the whole of london for a day, if not much more!
So turn your lights off at 8pm, and back on at 9 folks!
Ill be doing it!
