Minimising the environmental impact of School ICT in Dudley

It is estimated that ICT accounts for 2% of human induced global CO2 emissions.

In May 2008 a report from Ofsted warned that schools had not yet engaged with government plans for more sustainable schools. (Source: - Ofsted – “Schools and Sustainability, A Climate for Change”.)

All new school buildings should be carbon neutral by 2016.

How is the Dudley Grid for Learning contributing to the solution?

  • For DGfL2 ‘Refresh’ Dudley MBC selected the RM ‘Ecoquiet’ low energy model as the default replacement for up to 8,000 PC’s in Dudley schools. These use around two thirds less energy than the standard PC’s they replaced and emit less heat.

  • Assuming each PC will be in use for 5 hours per day for 39 school weeks it is estimated that each could save 99 kWh of electricity in a year. (Source:- RM Education plc.)

  • Assuming electricity costs at £0.10/kWh then 8000 such PC’s would save Dudley schools 792,000kWh and £79,200 in one year and an estimated £396,000 (at current prices) over the next 5 years.

  • CO2 emissions per kWh from electricity generation vary widely depending on the fuel used (Oil – 740g, Gas – 385g, Coal – 970g, (Source:- Energy Systems Research Unit, University of Strathclyde.) However in 2006 the International Energy Agency used a figure of 0.576kg CO2 per kWh when researching emissions for US homes.

  • If this figure of 0.576kg is applied to our annual schools saving of 792,000kWh then 456192kg of CO2 emissions is avoided.

If the PC’s have an anticipated life of 5 years there is a potential saving of over 2,280 metric tonnes of CO2 emissions.
