TL;DR
This study estimates historical electricity use by data centers worldwide and regionally on the basis of more detailed data than were available for previous assessments, including electricity used by servers, data center communications, and storage equipment.
Abstract
The direct electricity used by data centers has become an important issue in recent years as demands for new Internet services (such as search, music downloads, video-on-demand, social networking, and telephony) have become more widespread. This study estimates historical electricity used by data centers worldwide and regionally on the basis of more detailed data than were available for previous assessments, including electricity used by servers, data center communications, and storage equipment.

It is shown that the network electricity use associated with a wireless PDA cannot equal that of a typical refrigerator, even under the most extreme assumptions, and claims that wireless PDAs use as much electricity as a refrigerator are too high by more than a factor of 1,000.

Combining estimates of US computer room floor space for hosting facilities with total computer room power density, it is found that these US data centers in the aggregate required less than 500 MW of power in 2000, and used only about 0.12% of the electricity consumed nationwide in that year.

The results of this 2002 study indicate that although the data center had expanded its operations by roughly 33% from the previous year and increased the electricity demand associated with the computer equipment by 55%, the total computer room power density remained the same as the next year at 355 W/m2.
