Energy costs could skyrocket to more than half of overall IT budget in the next few years, warns Gartner.
Today, energy costs eat up less than 10% of IT budget, but unless companies pay closer attention to curbing the power-lust of datacentres this will cost both the environment and their budgets dearly.

“The bottom line is that the cost of power on this scale would be difficult to manage simply as a budget increase and most CIOs would struggle to justify the situation to board members,” warns research vice president Rakesh Kumar.
A major contributor to spiralling energy consumption is the popularity of high-density servers in datacentres over the last 12 months. Blades can rattle through 10 to 15 times the power needed for traditional servers, which older datacentres are struggling to manage. All this power creates vast amounts of heat requiring further power to cool systems down.
Gartner calls on CIOs to create 'greener' datacentres where possible and to apply pressure on suppliers to create more environmentally friendly systems. They should also delay moves to high-density systems by making better use of virtualisation to balance demand.
“The writing is on the wall for CIOs. Whatever way you look at it they have to take control of the impending power crisis and datacentre management will be crucial to that,” warns Kumar.
