“Green IT is an oxymoron, until you consider the use of IT to ‘green’ business and society.”
~Simon Mingay, Gartner Research
Estimates of annual global greenhouse gas (GHG) emissions from:
- Information and Communication Technologies (ICT): 2%
- Other sources: 98%
Estimates of NC State campus electricity-related GHG emissions from:
- ICT: 20%
The Hillsborough Building and Admin III (data center locations) are the largest consumers of electricity on campus!
- Other sources: 80%
Tech savvy and Green savvy – You can be both!
|For an average NC State office desktop computer with LCD monitor (100 watts) . . .||Cost and Emissions are . . .|
|One desktop running for 10 hours . . .||~$.076 electric bill
~1.2 lbs. CO2
|Annually, one desktop running
for 8 hours per workday and using power management . . .
(NOTE: If never turned off and with power management disabled, then
these numbers would be more than doubled.)
|~$63.30 electric bill
~252 lbs. CO2
|Annually, all of NC State’s more than15,000 office computers running
as noted above . . .
(NOTE: This does NOT include student computers, data centers, data network, telecom, printers, etc.)
|~$949,500 electric bill
~3,752,400 lbs. CO2
(~1,702.06 MTe CO2)
On the other hand, ICT enables carbon reductions
- Virtual travel, global communication
- Distance learning
- Telework, virtual meetings
- “Dematerialization” and e-business efficiencies
- SMART buildings, SMART grid, energy management
- Energy efficiency in Industry
- Advanced R & D for low-carbon solutions
For more ideas, see World Wildlife Fund’s ICT publications.
“As a whole, ICT is best viewed as a catalyst that can speed up current negative trends, or alternatively contribute to a shift towards sustainable development . . . “
Why should we care?
(beyond concern about a sustainable future!)
- NC State University Sustainability initiatives
- Presidents’ Climate Leadership Commitments, signed 2008
- NC Session Law 2007-546: Conservation of Energy and Water Use in State, University and Community College Buildings
- Finances (e.g., Facilities may begin billing departments for electricity.)
- Outreach & Education: Green IT Tips
- In classrooms
- In computer labs
- In offices
- In Data Centers and server rooms
- Purchasing (EPEAT and Energy Star, packaging and waste reduction)
- Reuse and e-cycling
“The most common ES initiatives under way in central IT are server consolidation and virtualization, centralization
of storage, recycling of e-waste, and minimizing growth in electrical energy use.”
Can we integrate energy and sustainability considerations into service planning and reporting?
- Miles not traveled?
- Pages not printed?
- Energy saved?
