Global warming forecasts rising temperatures melting ice and population dislocations due to accumulation of greenhouse gases in our atmosphere from use of carbon-based energy. There are strong arguments for and against the dire predictions of global warming yet one fact is undeniable over the past 10 to 20 years the inhabitants of Earth are collectively consuming more energy at a faster rate than ever before. As part of the response to improve energy efficiency and reduce greenhouse gas emissions many parts of the Federal government are instituting new policies. For example Executive Order 13423 signed by the President on January 24 2007 created the Office of the Federal Environmental Executive. OFEE is charged with promoting sustainable environmental stewardship throughout the Federal government. OFEE recognizes that electronics particularly computer electronics provide an opportunity for improved energy consumption. No where is this more apparent than in the data center where power consumption has doubled in the past five years and is expected to rise at a steeper rate of 76 from 2005 to 2010. One culprit is steadily increasing power requirements for servers. For example according to IDC 2006 the average small to medium size server required 150 W of power in 1996. These small to medium servers will require over 450 W by 2010. Of course increased power requirements means increased heat to dissipate driving another culprit for increased energy use in the data center cooling. One survey of IT executives shows that 45 of data center energy consumption goes to chiller cooling towers and computer room air conditioners CRACs . According to IDC 2006 in the year 2000 for every 1 spent on new servers 21 cents was .
