Businesses’ technology estates consume ever-greater amounts of energy and, at the same time, the cost of that energy continues to escalate. Green IT initiatives seem to have little effect despite the fact that, on paper, the ways to measure – and thus manage – energy consumption and efficiency are more sophisticated than ever before.

As The Green Grid publishes a new data center energy productivity (DCeP) metric – to sit alongside existing benchmarks such as power usage efficiency (PUE) and carbon usage efficiency (CUE) – we look at how organisations’ IT leaders are reacting to the developments in energy measurement and pricing techniques, and how these techniques sit alongside other proactive steps that can be taken by CIOs to reduce energy costs and boost Green IT initiatives.
