However, data center energy efficiency
improvements reduce operational costs, which ultimately impacts the price charged to customers, helping both the customer and provider to remain competitive.

Seeing the lack of a formal methodology for measuring data center energy efficiency
, The Green Grid (a non-profit, open industry consortium of end-users, policy makers, technology providers, facility architects, and utility companies) introduced the calculation of a new energy efficiency metric called power usage effectiveness (PUE) that went on to become the widely accepted industry de facto standard.
Then there is a discussion of the impact of implementing the new ASHRAE (2008b) Environmental Guidelines for Datacom Equipment on the data center energy efficiency
lt;p>Seventy-two percent of those surveyed said the size of the investment was the primary barrier to improving their data center energy efficiency
, followed by lack of specific information on the return of the investment for making changes (38%), server down time required to implement changes (38%), and concerns about running legacy software on new systems (34%).
The survey also showed that data center energy efficiency
is fast becoming a priority in the industry, with 42% of survey respondents saying they have either analyzed efficiency or are currently analyzing it.

However, optimizing data center energy efficiency
requires moving from traditional data center densities (2 kW to 3 kW per rack) to an environment that can support much higher densities (in excess of 30 kW).
