Benign ATL obsession: green computing
From an altruistic perspective, green computing is mostly about carbon footprints. One medium-size data center can generate 10,000 metric tons of carbon per year (because of the power it uses). Large carbon footprints are not exactly bad for business--not directly--but they can result in negative publicity. In that sense, going green can have PR benefits--you can position yourself as a socially responsible enterprise, at least with respect to IT.
