1. Helping to monitor and power down idle office computers
- A typical desktop computer and monitor will consume about 920 kWh of electricity if left on all year, but only 190 kWh if powered down overnight, weekends and holidays. This currently (2009) equates to an annual saving of £86 and 392 kg CO2eq. per computer. We estimate at least 8000 computers across the collegiate University are left on all the time unnecessarily. With a robust approach to power management there is a potential annual saving of £690,000 and 3,100 tonnes CO2eq. (At least 90% of the 12,000 undergraduates bring a laptop to the University but we do not know how these, and other portable computing devices are managed).
- The University of Oxford has set greenhouse gas emission targets for 2010, 2020 and 2050. From April 2010 the CRC Energy Efficiency Scheme will require the University to report and pay for greenhouse gas emissions. The data will be used to place the University in a performance league table which will be published annually. From 2011, the HEFCE Carbon Management Strategy states capital allocations will be linked to carbon reduction. Higher education institutions (HEIs) in England are required to develop individual carbon reduction strategies, targets and associated carbon management plans.
- OUCS, OeRC, OUCE and Estates have developed power management monitoring (PMM) and wake on LAN (WOL) facilities to help units implement their own green desktop computing initiatives. To use these facilities OUCS must install FiDo software on the local IT network. There are also a wide range of commercial solutions available and several groups have found it cost-effective to develop their own in-house solutions.
