Over the last decade, the University has implemented a number of green technologies 1) Change computing policies: a) More energy efficient hardware b) Virtualization c) Thin and thick Clients 2) Overhauled printing practices in sites

1) When not in use, Computers 4 modes a) Do nothing, run normally (almost never used) b) Standby, turns monitor off i. HD may or may not spin down, some other controls c) Sleep, turns all off but network d) Turn off entirely

1) Standard desktop used 2000 hours per year and Standby uses approx $110 in electricity a) 170W in use, 85W standby, 10W Sleep b) All savings from standby -> Monitor. c) CPU uses same in standby as in use! 2) Same machine using sleep mode: $50 per year, saves $60 or 55%. 3) Turning off when not in use saves and additional $6 (could use hibernate)

1) Laptops use 30-50W overall, far more efficient. a) When using hibernate usage to zero, b) consumption varies with usage level c) Stepping mode, brightness, etc. 2) iMacs, use about 80W awake, 40-50W sleep or standby (same), about $60 a year. 3) MacPros same or more usage than desktop depending on configuration.

1) Sunray with 20” monitor: a) $14 per year b) Even when considering back-end servers, they save 75% of a desktop using standby c) Save as much as $75 per year per unit d) Similar with all-in ones or box units. 2) Nettop: a) 30W Running/Standby+ Monitor b) Approx $40/yr. using standby c) Approx $20/yr. using sleep

1) GW 24”, 100W + 5W $30 yr 2) 20” LCD, 70 W + 3W $20 yr. 3) 20-28” Low power (fleuro OR LED) 20-25W + 1W $6 yr. 4) Cost of new monitor $ , saves up to $24 yr.

1) Appliances, Refrigerator 2) Lighting 3) Comparisons – see the web

Major transition over past five years 1) SunRays a) Over 45% of site machines now SunRays b) Three terminal servers host 77 machines c) Christiana, Dickinson, Harrington Sites d) Kiosks in Trabant and Perkins 2) iMacs in sites a) More efficient b) Flexible, Win or Mac OS 3) Use of sleep mode transitioned from Standby or turned off overnight

1) 2008 CS&S Server Renovation a) Initially 18 physical servers b) 10 Virtualized (8 site plus 2 core/admin) c) Two virtual hosts d) Net savings per machine: $160, and this was a low ratio. $1600/yr. in electricity e) Other costs as well: Cooling, space, etc. f) Ended up using excess capacity for testing g) Ratio of 8:1 easily obtainable -> $180 per machine in electricity alone.

1) 2010 CS&S lead KACE management appliances a) Cooperative alliance, cost sharing b) Thirteen campus units and growing c) Ten servers requested, more to be added d) All running on single virtual host e) Second virtual host to add redundancy f) Dramatic power savings, approx. $1600/yr.

1) One of UD’s Largest Success stories 2) million sheets printed a) Up to 80% wasted -> Proofs/Never picked up 3) 2002 implemented PrintLess Campaign a) Posters and web pages b) Charging for printing c) Usage down 80-90% d) Below 1 million sheets ever since 4) All sites use recycled paper 5) All toner cartridges recycled. 6) Transition to Webfoms

1) Five years ago: a) Pay to haul away hazardous waste per weight 2) Central receiving a) Collects b) Offers for redistribution/parts for 30 days c) Transports monthly to DSWA d) DWSA processes at no cost to UD.

1) Kill-A-Watt EZ4460 a) $25 at Amazon.com b) Plug it in in-line c) Set utility rate ($0.11 approx here) d) Collects data i. Instantaneous readout ii. Running average iii. Yearly estimate 2) Lots of stats available on the web

1) Power transformers draw significant power? a) Cell Phones and chargers b) Laptops c) Parasitic Transformers 2) Reality: Cell phone charger a) plugged in $0.85 yr. b) Charging and plugged in $1.65 yr. 3) Remainder near zero when not in use.

1) Sleep Mode (downside: no terminal in) 2) Thin or Thick Clients 3) Virtualize as possible 4) General conservation (lighting appliances) 5) Discourage Printing a) Charging works b) Electronic Submission 6) Kill-A-Watt

1) Standard is 2GB mem + 320GB HD 2) Acer Veriton, D525+ION2 $475 (Amazon) 3) Lenovo Ideacenter Q150, D510 + ION, 2GB $500ish 4) Asus Eebox, D525 +ION2+ Slot DVD $519 (Amazon) 5) Dell Opti 160, Generation 1 a) Atom 330, 4GB, b) 64GB slow SSD, c) slow graphics d) List $917, UD $754

1) Cost a) Available w/o HD or memory $209 b) 4GB DDR3 laptop memory $58 c) 64 GB SSD $100 d) Total cost: $367 2) Features a) Ion2 Graphics, makes it usable, HD Video b) HDMI + DVI, capable of dual monitor c) SDHC d) Wireless N + Gigabit e) 5 USB + eSATA f) Not recommended for distribution, No support
