8 Problem Statement Why Data Centers?  Highly energy-intensive and rapidly growing  Consume 10 to 100 times more energy per square foot than a typical office building  Large potential impact on electricity supply and distribution  Used about 45 billion kWh in 2005  At current rates, power requirements could double in 5 years.

9  Lack of efficiency definitions for equipment and data centers ( Being addressed by )  Service output difficult to measure, varies among applications  Need for metrics and more data: How do we account for computing performance?  Split incentives  Disconnect between IT and facilities managers  Risk aversion  Fear of change and potential downtime; energy efficiency perceived as a change with uncertain value and risk Key Barriers EPA Report: Call for Pilot Projects, Test Centers, Federal Leadership by example

10 Energy Efficiency Opportunities Server Load/ Computing Operations Cooling Equipment Power Distribution & Conversions

11 Data Center Energy Use Typical Data Center Energy End Use Server Load /Computing Operations Cooling Equipment Power Conversions & Distribution 100 Units 33 Units Delivered 35 Units

12 Typical Energy Flow/Use Server Load/ Computing Operations Cooling Equipment Power Conversion & Distribution Delivered Power Electricity Generation & Transmission Losses Fuel Burned at Power Plant

13 Will reduce cooling needs Typical Energy Flow/Use Server Load/ Computing Operations Cooling Equipment Power Conversion & Distribution Reducing server power requirements Lowering power conversion losses Electricity Generation & Transmission Losses Delivered Electricity …ultimately reducing fuel burned at the power plant Reducing power demand and losses Fuel Burned at Power Plant On-Site Generation further reduces losses and emissions!

14 Server Load/ Computing Operations Cooling Equipment Power Conversion & Distribution Alternative Power Generation High voltage distribution Use of DC power Highly efficient UPS systems Efficient redundancy strategies Load management Server innovation Energy Efficiency Opportunities Better air management Move to liquid cooling Optimized chilled-water plants Use of free cooling On-site generation CHP applications Waste heat for cooling Use of renewable energy Fuel cells

Advanced Liquid Cooling  The use of liquid cooling of servers enables reductions in power by rejecting heat directly outside into ornamental cooling ponds, or the re-use of heat for office heating in the winter.

Ornamental Cooling Ponds Traditional Approach Replace Tower with Pond, in Summer. In Winter, re-use Heat for Office Spaces
