Power-guzzling hardware is just the "tip of a melting iceberg" of a green agenda that CIOs and IT suppliers cannot ignore.
Cutting costs is the biggest incentive for CIOs to "think and act green", analysts explained at the Gartner Symposium/ITxpo in Cannes.
Large companies that ignore the green issues could see energy costs quadruple from 4% to 8% of IT budget up to 16% to 32% within five years.
It’s essential that CIOs must make short and long-term plans to tackle power consumption inside and outside the datacentre. This means taking a fresh look at lifecycle management to find ways to minimise the impact of IT on the environment. IT heads must also put pressure on IT suppliers to employ green practices.
“CIOs need to ask suppliers and service providers about their activities to reduce greenhouse emissions and their broader environmental policies,” says Rakesh Kumar, research vice-president at Gartner.
