According to Booz & Company, data centers accounted for 1.5 percent of total U.S. energy consumption in 2006. Energy usage at U.S. data centers will likely double between 2006 and 2011.
1-2 megawatt data centers are now common. By 2015, 10 to 20 megawatt datacenters are likely.
Popular plans: green building methods, solar power, water and ambient air exchange for cooling, lighting, server and rack configurations, and virtualization.
Two primary metrics: power usage effectiveness (PUE) and Data Center infrastructure Efficiency (DCiE) measure energy consumption and efficiency.
Advanced monitoring tools allow management of data center systems on areal-time basis; the best measure output down to individual electricaloutlets and receptacles.
Automated control systems allow adjustments to data center, cooling and network energy use as needed.
Ambient air exchange systems can provide massive energy savings. Most effective in cooler climates, but effective 50 percent of the time in places like Phoenix and Las Vegas.
Server virtualization, blade servers and more efficient cabling trim energy costs as much as much as 80 percent.
Organizations can trim energy costs by 40 percent or more by adopting hot-cold aisle configurations, smart cooling systems, and raising ambient air temperatures by a few degrees.
Green sourcing and supply chain strategies consider green life cycles of equipment and IT systems.
Google, Facebook and other data-centric firms are locating data centers in cooler climate regions and areas with sustainable energy sources such as solar, wind, and hydroelectric.
The Green Grid consortium is a leader with metrics, calculators, and best practices.
Consumers are choosing to conduct business with environment conscious companies that have clear sustainability initiatives.
