British companies have been warned they must increasingly take into account their energy use or risk facing power blackouts in the future.
Research from the DMW Group reveals despite concerns over energy expenditure, too few firms are not taking any steps to reduce the energy expenditure of their data centres.
The group has outlined a ten-point plan to help businesses lower the amount of energy used by their IT operations.
It advises enterprises to monitor their systems to detect power supply issues and to introduce staggered business recovery plans to switch off non-critical systems.
Simon Williams, director at DMW Group, said: "Not measuring your current IT power consumption means that many IT managers are unlikely to have a sound plan for reducing their power requirements."
He added that IT managers should establish a programme to measure energy usage and potential methods of reducing it.
In November 2007, a Computerworld blog warned internet users could be hit by power "brownouts" - patchy energy supplies, as soon as 2010.
