I am with the other guy there in doubting that one google search makes them emit that much co2. I would like to see how they calculated those numbers. I hope they took into account that not all electricity on the grid is coal... also if anything google is doing more than most to fight this server farm problem.

I don't know if they actually have plans to build it, but at least they're thinking!
