Google Pushes for Electrical Efficiency

SAN FRANCISCO, Sept. 25 -- Google is calling on the computer industry to create a simpler and more efficient power supply standard that it says will save billions of kilowatt-hours of energy annually.

In a white paper to be presented Tuesday on the opening day of the Intel Developer Forum here, two leading data center designers at Google will argue that the industry is mired in inefficiency for historical reasons, dating to the introduction of the first I.B.M. PC in 1981.

and making the computers use less electricity will not only save energy that way but they will make less heat and will save on electricity used for air conditioning because a computer can heat up a room quite a bit
ah but there is a catch. the quieter(due to needing less power and thus cooler) the computer the more people leave it on.
you can even test this out.
Big machines-the server farms at Google-are on 24/7 anyway. so is my laptop.
Thanks to ACPI and IPMI, a properly designed computer can take its power consumption down to miniscule levels (sub-watt) when it is not used.

Which allows us to ignore it in good conscience.
