hyperscale data centres globally( up from 259 in 2015) to reach US $ 21.14bn by 2032. Directto-chip liquid cooling systems pump coolant directly to processors through cold plates, achieving 30-40 % energy efficiency gains whilst handling extreme power densities. Immersion cooling goes further, submerging entire servers in dielectric fluid that doesn’ t conduct electricity but efficiently removes heat. The efficiency gains are substantial. Google’ s facilities already achieve 1.1 PUE( Power Usage Effectiveness) compared to industry averages of 1.67-1.8. This means that for every watt used by
