Power and cooling are becoming part of the IT strategy for the first time in history. 

For most organisations the datacenter is the biggest user of energy even as the corporate executives are looking to be good corporate citizens. So the datacenter or facilities manager needs to engage the top management proactively in administering energy and making purchasing decisions together.

To do this effectively, they need to define a baseline of energy utilization, and then target legacy systems and big energy users that use energy irresponsibly, and commence projects to replace them and then be able to quantify the energy and carbon savings so their CEO can say "we just saved the world X amount of carbon emmissions" or to get that carbon credit!

Technology refreshes for the first time in history are creating problems in datacentres as the various forms of high density technologies being deployed actually increase the power usage per sqm. While the datacentre will become more efficient it will also consume even more power - it's a dilemma.

Lots of new initiates and innovation is occurring in power and a cooling technologies and customer concern over "bleeding edge technology" is real.
