        Until recently, society has taken the existence and operation of data centers for granted. Today, there is an emerging debate regarding their huge consumption of electricity and carbon dioxide (CO2) emissions. The article observes: Approximately 6,000 data centers in the US, for instance, consumed roughly 61 billion kilowatt-hours (kWh) of energy in 2006; ... The total cost of that energy, $4.5 billion, was more than the cost of electricity used by all the color televisions in the US in 2006. More importantly, "the DOE reports that data centers consumed 1.5 percent of all electricity in the US in 2006, and their power demand is growing 12 percent a year." Furthermore, apart from power, the data centers also use resources in terms of cooling and space, which are both becoming limiting factors. Several approaches are reported regarding what is being done or what can be done to alleviate the problem, such as using more hydroelectricity co-located with the data centers, using air cooling, and installing personal energy meters. Some industry consortia, such as the Green Grid consortium, meet to share best practices. The intent of this article is to raise awareness at a general level. At the same time, the research community has been addressing these issues with concrete tools and innovations-for example, the European Cooperation in Science and Technology (COST) Action IC0804 (http://www.cost804.org/).
