IBM ran a multi-page campaign on its green servers in one of India’s financial news papers last week. Here is Sun’s OpenECO initiative. BTW, here is a recent article on (perceived) greenness of x86 servers from big vendors. It is based on a survey from Gabriel Consulting Group.
Welcome to the Green Rush. (Incidentally, just like Gold Rush in the past, this fever showed its most visible signs in the state of California (you may remember those power outages) and is spreading fast to rest of the globe too.)
Gabriel, Gabriel, who is the greenest of all? :-).
