Computer servers that earn the ENERGY STAR will, on average, be 30 percent more energy efficient than standard servers. If all servers sold in the United States meet this new specification, energy cost savings would approach $800 million per year and prevent greenhouse gas emissions equivalent to those from over one million vehicles.
Data centers support every sector of the economy including financial services, media, academia, manufacturing and government, to name a few. Data centers house the IT equipment used for data processing, data storage, and communications networking. These operations are essential to aiding business processes, information management, and communications functions.
According to EPA's report to Congress, data centers will account for nearly 3% of total US electricity consumption by 2011. Computer servers are at the core of data center operations, and therefore contribute greatly to this overall consumption. Deploying more energy efficient servers can be a key strategy to reduce total data center energy consumption.
Only rack and pedestal computer servers designed to be used in the enterprise environment and containing 4 processor sockets or less are eligible for ENERGY STAR qualification.
Servers can earn the ENERGY STAR by offering the following features:
Standard computer servers can consume between 1,200 – 8,600 kWh annually. Companies that purchase ENERGY STAR qualified servers could save as much as 1,000 kWh per server. Over a five-year lifetime, companies could save as much as $500 for each server they install.
By choosing ENERGY STAR and taking steps to optimize the utilization of your computer servers, you are helping to fight global warming and promote cleaner air, while improving overall data center efficiency.
