Design Company Hudson-Powell have created a great poster encouraging us to turn off our lights in the name of "Do The Green Thing". The background behind it reminds us that, while most of us turn lights off at home when not in use, thousands of offices are lit up throughout the night when they needn't be.
I think this poster around the work place would certainly add some charm and be a much nicer reminder than many of the other energy saving posters I have seen.
