The U.S environmental Protection Agency estimates that the energy requirements for data centers will be doubled in the next five years. Here comes the need of alternative resources like solar array, natural gas turbines, wind power, fuel cells and hydro power. But few of companies have already started making use of these alternative options to save on power consumption in their data centers.

We look at the construction and design of both types and present results demonstrating that high-density DCs are a better choice for reducing the owners cost. These results apply to new construction and mostly-unconstrained retrofits. Densities of 1000 watts per square foot of work cell are being achieved with good efficiencies. Modern designs of 200 to 400 watts per square foot of work cell are much more common, but cost more. Costs of the architectural space, power systems and cooling systems are reviewed as are the operational costs for these systems. High-density DCs do cost less. The challenges for the high-density DC are also called out and suggestions for successful operation are made.

Continuous measurement of power usage by all these elements lets us monitor the health, operating cost, and relative efficiency of our data centers. As we outline below, our approach has led to state-of-the-art efficiency
