Climate Change and IT
•
IT causes 2% of global CO2
emissions (Gartner 2007)
•
2020 IT emissions = 4% of
global CO2 emissions(McKinsey)
•
The problem: Emphasis on
Efficiency over Sustainability
•
Efficiency ≠ Sustainability

Efficiency vs. Sustainability in Data Centers
•
•
PUE : Power usage effectiveness
•
Measures how much energy is
wasted (cooling) per useful
kilowatt hour
•
•
Typical PUE ranges from 1.5-2+
PUE = Total Facility Power/IT
Equipment Power
PUE < 1.5 said to be green

GPUE = Green Power Usage Effectiveness
greenqloud
G = Weighed Sum of energy sources and their lifecycle KG CO2/KWh
G =∑( %EnergySource x ( 1 + weight) )
GPUE = G x PUEx
or = G @ PUEx
•
Weighs PUE for comparing DC to DC true greenness
by including their energy sources
•
•
Lifecycle CO2 emissions per usable KWh for computing
PUE 1.20, 50% Coal / 50% Hydro
G = 1.531, GPUE = 1.84 or [email protected]
CO2 per usable KWh = (G-1) x PUE = 0.64 Kg

Ergo: Funny cats are causing
climate change* and we need to
do something about it.
* Figuratively speaking...

Saving the world from funny cats
•
Data centers are the biggest
polluters in IT - dirty energy
•
Cloud computing and internet
use are driving the need for
more data centers
•
We have a great opportunity
to fight climate change with IT
•
The key is using renewable
energy behind the clouds!
