Staffordshire University has saved around £27,000 a year by making its computers more energy efficient. It introduced software letting it centrally control and reduce the energy used by the 4,000 PCs on its network by 60%.
When switched on, the average PC draws 65 watts of electricity, 3 watts when suspended (standby), and 1 watt when completely turned off. Each monitor also draws 35 watts when on, 2 in sleep mode and zero when off.
Steve Bignell, at IT energy management firm Verdiem which provided the software said: “On an individual PC basis this doesn’t equate to massive savings – but when you’re a large organisation such as Staffordshire University and you have thousands of PCs spread out across multiple locations and campuses, these figures combine to create thousands of pounds worth of wasted power consumption.”
