Reducing our carbon footprint

1. Reducing our Carbon Footprint Tom Raftery blog: tomrafteryit.net blog: synergymodule.com blog: cix.ie podcast: podleaders.com email: tom@tomrafteryit.net Wednesday 7 November 2007 1

2. Background • Social media? • Building a Data Centre • Cork Internet eXchange (CIX) • First in Ireland outside Dublin Wednesday 7 November 2007 2

3. Geek Porn! Wednesday 7 November 2007 3

10. Inﬂuencing factors • Controlling DC running costs • Stafﬁng - reasonably controllable • Connectivity - decreasing • Energy - increasing • => focus on energy Wednesday 7 November 2007 10

11. Current energy situation Electricity Wind Energy Wind Demand 5GW max 0.9GW max 6.5% 2006 avg 1.8GW min 0.0GW min Wednesday 7 November 2007 11

12. 2025 energy situation Electricity Wind Energy Wind Demand 10GW max 6.3GW max 33% 2025 avg 3.6 GW min 0.0GW min Wednesday 7 November 2007 12

13. The Problem! • Wind energy de-stabilises grid • Current grid infrastructure can’t take any more • Currently 2GW outstanding Wednesday 7 November 2007 13

14. Wind Energy supply Wednesday 7 November 2007 14

15. Energy Demand Wednesday 7 November 2007 15

16. Current energy situation - problematic Electricity Wind Energy Wind Demand 5GW max 0.9GW max 2006 6.5% 1.8GW min 0.0GW min Wednesday 7 November 2007 16

17. 2025 energy situation Electricity Wind Energy Wind Demand 10GW max 6.3GW max 2025 33% 3.6 GW min 0.0GW min Wednesday 7 November 2007 17

18. 2025 energy situation Electricity Wind Energy Wind Demand 10GW max 6.3GW max 2025 33% 3.6 GW min 0.0GW min Wednesday 7 November 2007 18

19. Also Climate Change Wednesday 7 November 2007 19

20. 3 Energy strategies • Build a hyper energy-efﬁcient DC • Network data centres • Energy Demand Management Wednesday 7 November 2007 20

21. Energy efﬁcient DC Standard DC CIX 33% 12% Chiller 3% <1% Humidiﬁer 9% 4% CRAC 30% 80% IT Equipment 5% 0.01% PDU 18% <2% UPS 1% <1% Lighting 1% 1% Switch Gear Wednesday 7 November 2007 21

22. DC Power Network • Create a Data Centre power network • Network generates power for grid by day and pulls surplus power from grid by night • Give control of network to Eirgrid • Eirgrid can now buy more wind power Wednesday 7 November 2007 22

23. More Geek Porn! Wednesday 7 November 2007 23

25. Energy Demand Management • Can’t control supply • => Control demand • => Energy Demand Management Wednesday 7 November 2007 25

26. Energy Demand Management • Energy Reduction • Diesel Generators • Heating and Cooling Thermostat Control Wednesday 7 November 2007 26

27. Energy Demand Management • Energy Time Shift • Refrigeration • Ice Bank Air Conditioning • Storage heating • Smart Domestic Appliances Wednesday 7 November 2007 27

28. Energy Demand Management • Energy Demand Stimulation • Swimming Pool Heating (via Heat Pump) • Plug In Hybrid Vehicles (Toyota Prius 2009) • H2 production Wednesday 7 November 2007 28

29. Energy Demand Management Incentives • Single Energy Market • Dynamic energy pricing • Reduced energy bills • Reduced carbon footprint Wednesday 7 November 2007 29

32. Synergy Module Eirgrid NCC Synergy Module NCC Synergy Synergy Synergy Synergy Module Module Module Module Diesel Refrigeration Ice Bank PIHV Generator Wednesday 7 November 2007 32

33. Conclusion • Wind power has massive potential • Wreaks havoc on grid • EDM can counter the instability • => Greater use of wind energy Wednesday 7 November 2007 33

34. Last bit of Geek Porn! Wednesday 7 November 2007 34
