FOOTPRINTING RESULTS (kWh) University of Sheffield University of Sheffield (ex HPC) Lowestoft College Total Electricity 8,680,806 (100%)7,472,188 (100%)453,714 (100%) PCs & monitors 4,164,477 (48%)4,164,477 (56%)197,402 (44%) Servers 1,520,736 (18%)1,520,736 (20%)135,999 (30%) HPC 1,208,617 (14%)00 Imaging 835,659 (10%)835,659 (11%)42,171 (9%) Networks 687,362 (8%)687,362 (9%)68,538 (15%) AV/Telephony 3%4%3%

6. HE HAS A LARGE FOOTPRINT 760,000 PCs 215,000 servers 147,000 networked printers 512,000 Mwh of electricity 275,000 tonnes of CO 2 Over £60 million in 2009 - £1 million at Sheffield Reaches many students

7. WHY GREEN ICT? - ENERGY COSTS OF PCs High energy, high-usage PC with no power management could cost £61 per year in electricity (505 kWh/y @ 12p/kWh) Low energy, low-usage PC with power management could cost £3 per year (25 kWh/y @12p/kWh) Whole life costing essential
