What’s the problem?
Climate change directly related to CO2 emissions ICT industry footprint = Aviation
Will double until 2020 Our focus so far: Data centers
Found in enterprises, universities, Internet services Energy consumption translates into high operational cost Energy consumption (indirectly) releases CO2 into the air
ICT = Information and Communication Technology [Climate Group’08]

Impact of data centers
Electricity usage of worldwide DCs [JK’11]
CO2 of worldwide DCs [Mankoff’08]
1.5%
Mega data center
Microsoft DC in Quincy, WA
Mega data center
Microsoft DC in Chicago, IL
Small data center
Small and medium data centers dominate
What’s the solution?
Reduce footprint by leveraging renewable energy
Bring solar and/or wind Co-location
Self-generation

Main challenge: Supply of power is variable!
Solar power
We need to match the energy demand to the supply
