Do your bit
A desktop computer and monitor will consume about 920 kWh of electricity if left on all year, but only 198 kWh if powered down overnight, weekends and holidays. This currently equates to an annual saving of £86 and 387 kg CO2eq. per computer. UK Further and Higher education organisations own about 1,470,000 desktop computers and most undergraduates and many researchers will charge laptops and other devices while on site.
There is an obvious need for IT managers to implement robust policies to ensure computers are powered down safely and reliably when they are idle. There are now a wealth of tools and techniques that make better power management possible, and many groups have achieved just this.
Powering down computers when they are idle is not as easy as switching lights off, but considering the current economic situation and climate science, there are certainly many reasons for us all to do your bit!
