Since 2007, for example, Cavern Technologies has operated a data center 125 feet below ground in an abandoned limestone mine. The mined out area underground, which covers 3 million sq. feet, is 15 minutes outside of Kansas City, Mo. Unlike other mines, the Cavern facility was created with the idea of reuse in mind, so floor space isn't irregularly shaped like other underground facilities can be, says president John Clune. The area's relatively low electricity costs, at 3.5 cents per kilowatt-hour, help to make operating costs lower than those in other parts of the country, he adds.
