▁up ward ▁tr end ▁of ▁ 4 % ▁is ▁predicted ▁to ▁continue ▁through ▁ 2 0 1 4 - 2 0 2 0 . ▁In ▁ 2 0 1 1 , ▁energy ▁consumption ▁from ▁all ▁data ▁cent ers ▁equ ated ▁to ▁roughly ▁ 1 . 1 ▁to ▁ 1 . 5 % ▁of ▁total ▁global ▁energy ▁consumption . ▁Information ▁and ▁communication ▁techn ologies , ▁including ▁data ▁cent ers , ▁are ▁responsible ▁for ▁creating ▁large ▁quantities ▁of ▁ ▁em issions . ▁It ▁is ▁estimated ▁that ▁by ▁ 2 0 2 0 ▁they ▁will ▁account ▁for ▁ 1 2 % ▁of ▁total ▁global ▁em issions . ▁ ▁Google ’ s ▁green ▁initi atives ▁▁ ▁The ▁energy ▁used ▁by ▁data ▁cent ers ▁is ▁not ▁only ▁to ▁power ▁their ▁servers . ▁In ▁fact , ▁most ▁data ▁cent ers ▁use ▁about ▁half ▁of ▁their ▁energy ▁costs ▁on ▁non - comput ing ▁energy ▁such ▁as ▁cool ing ▁and ▁power ▁conversion . ▁Google ' s ▁data ▁cent ers ▁have ▁been ▁able ▁to ▁reduce ▁non - comput ing ▁costs ▁to ▁ 1 2 %. ▁Furthermore , ▁as ▁of ▁ 2 0 1 6 , ▁Google ▁uses ▁its ▁artificial ▁intelligence ▁unit , ▁Deep M ind , ▁to ▁manage ▁the ▁amount ▁of ▁electric ity ▁used ▁for ▁cool ing ▁their ▁data ▁cent ers , ▁which ▁results ▁in ▁a ▁cost ▁reduction ▁of ▁roughly ▁ 4 0 % ▁after ▁the ▁implementation ▁of ▁Deep M ind . ▁Google ▁claims ▁that ▁its ▁data ▁cent ers ▁use ▁ 5 0 % ▁less ▁energy ▁than ▁ordinary ▁data ▁cent ers .
