10 gram
CO2
(boiling 250 ml water)

“Performing two Google searches from a desktop
computer can generate about the same amount of
carbon dioxide as boiling a kettle for a cup of tea,
according to new research.”
(The Sunday Times)

Google handles about
1,000,000,000,000
searches per year
12.
To do so, Google deploys
an estimated 500,000 servers
in about 50 data centre worldwide
(these are rough estimates,
Google isn't telling)
13.
Note the cooling plants ...
Google's data centres in Dalles, Oregon
14.
Each data centre consumes about 50MW
Cooling requires most of the power
Infrastructure cost is about $22,000/kW
Reducing power consumption can result in
huge cost savings
