PALO ALTO, U.S. -- Google reckons it will be able to power all of its global operations using only renewable sources starting next year, thanks to energy-saving data center improvements and lower generating costs.
The U.S. search giant consumed 5.7 terawatt-hours of electricity in 2015 -- roughly as much as San Francisco. Its 13 data centers around the world accounted for 95% of this usage. The company also has offices in 150 cities scattered across about 60 countries.
