sorry to be a geek, but this is my industry and what they dont tell you is that this sort of action actually produces more CO2 then using electricity normally, just like all the CR!P about wind turbines, i wont bore any one with the techy stuff, i'm all for saving energy, i turn everything off in Bahrain where we dont even have to pay for the electricity but these green actions are nothing of the sort. still hope you had fun playing games in the dark - just hope your beer or wine stayed chilled
