The company says that this makes it the first major internet services company to be awarded external certification of both ISO14001 and OHSAS 18001 for all its data centers (pictured).
Google did two things to improve efficiency of its backup generators. First it minimized the generators’ amount of run time and need for maintenance. Second, it worked with the generators’ manufacturers and oil companies to extend time between oil changes.
The company says that these actions are part of a continuing efficiency drive, but that so far the genrators’ oil consumption is down by two-thirds.
Google’s data centers in the following U.S. locations have received this dual certification:
- The Dalles, Ore.
- Council Bluffs, Iowa
- Mayes County, Okla.
- Lenoir, N.C.
- Monck’s Corner, S.C.
- Douglas County, Ga.
The company plans to pursue certification in its European data centers as well.
In September last year, Google broke silence on its energy consumption, revealing that it used 2,259,998 MWh of power in 2010. According to some online sources that figure is higher than the consumption of Salt Lake City.
