  2. 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]

  3. Impact of data centers 1.5% CO2 of worldwide DCs [Mankoff’08] Electricity usage of worldwide DCs [JK’11]

  4. Mega data center Microsoft DC in Quincy, WA

  5. Mega data center Microsoft DC in Chicago, IL

  6. Small data center Small and medium data centers dominate

  7. What’s the solution? • Reduce footprint by leveraging renewable energy • Bring solar and/or wind • Co-location • Self-generation • Small and medium data centers

  8. Solar and wind are clean g CO2e per KWh over lifetime [Sovacool’08]

  9. Solar is more available than wind in the US Wind Solar [NREL’12]

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

  11. Addressing the challenge with Parasol • Solar-powered computing • On/off grid • Software to exploit renewables within and across DCs • Tradeoff between • Renewables • Batteries • Grid energy Solar Available Power (kW) Time

  12. December’10 April’12

  13. Parasol inside and outside

  14. The Rutgers Parasol Project http://parasol.cs.rutgers.edu
