Data Center Energy Efficiency.

Data centers consume 1.5% of the world’s energy, a figure which doubled between the years 2000 and 2006, and which will double again in the next five years. On scale with the airline industry, data centers are second only to heavy manufacturing in terms of energy use and, as a result, are a significant source of greenhouse gas emissions. The EPA states that the growth in demand for data centers is driven by increases in electronic transactions in financial services, expanded use of internet communication and entertainment, a shift to electronic medical records for healthcare, and growth in global commerce and services.
