Data Centers and Servers
Data centers are one of the most energy-intensive building types, consuming 10 to 50 times the energy per floor space of a typical commercial office building. Collectively, these spaces account for approximately 2% of the total U.S. electricity use, and as our country's use of information technology grows, data center and server energy use is expected to grow too. Fortunately, there are many opportunities to reduce energy use in data centers.
