Steve Prentice, research VP at Gartner, said IT is uniquely positioned to confront increasing energy costs as the technology is one of the largest consumers of power within organizations.

"You cannot keep it a secret," Prentice said. "Performance-per-watt will become critical over next decade."

During his keynote address at this year's Gartner Data Center Summit in Sydney, Prentice said that as hardware prices continue to fall and power costs continue to rise, heat generation becomes a problem when organizations take advantage of commodity hardware, "and it's getting worse".

"The requirement for modern hardware is going to be huge [and] for every watt that goes into a processor you will use another watt to cool it," he said, adding vendors' promotion of low-power consumption products is indicative of this trend.

Prentice cited the Barcelona Supercomputer Center's 4800-processor cluster as an example of the scale of power consumption by computers. Reports have it that 75 percent of the university's electricity is being consumed by the supercomputer.
