I am really skeptical of this, Patrick. PUE's of between 1.2 and 1.3 -
sure. But below 1.2 on an annual basis? And its not even their newest
facility. Color me skeptical.

Google has released its PUE numbers:

There is a nice explanation of this, including a graph showing why
DC efficiency is more important than machine efficiency (on the
second page) at this link:

I think GOOG deserves a hearty "well done" for getting a whole DC
under 1.2 PUE for a whole year. (Actually, I think they deserve a
"HOLY @#$@, NO @*&@#-ing WAY!!!")
Personally, I think only a self-owned DC could get that low. A
general purpose DC would have too many inefficiencies since someone
like Equinix must have randomly sized cages, routers and servers,
custom-built suites, etc. By owning both sides, GOOG gets a boost.
But it's still frickin' amazing, IMHO.
For their next miracle, I expect GOOG to capture the waste heat from
all their servers and co-gen more electricity to pump back into the
servers. :-)
