	Energy demand from digitalisation occurs in data centres, which are dedicated buildings or part of buildings for accommodating large amount of information technologies equipment such as servers, data storage and communication devices, and network devices. Data centres are responsible for about 2% of global electricity consumption ( [[#Avgerinou--2017\|Avgerinou et al. 2017]] ; [[#Diguet--2019\|Diguet and Lopez 2019]] ). Energy demand from data centres arises from the densely packed configuration of information technologies, which is up to 100 times higher than a standard office accommodation ( [[#Chu--2019\|Chu and Wang 2019]] ). Chillers combined with air handling units are usually used to provide cooling in data centres. Given the high cooling demand of data centres, some additional cooling strategies, such as free cooling, liquid cooling, low-grade waste heat recovery, absorption cooling and so on, have been adopted.

	provide useful heat for industrial and building applications. More recently, data centres are being investigated as a potential resource for demand response and load balancing ( [[#Zheng--2020\|Zheng et al. 2020]] ; [[#Koronen--2020\|Koronen et al. 2020]] ). Supplying data centres with renewable energy sources is increasing ( [[#Cook--2014\|Cook et al. 2014]] ) and is expected to continue to increase ( [[#Koomey--2011\|Koomey et al. 2011]] ). Estimates of energy demand from digitalisation (connected and small appliances, data centres, and data networks) combined vary from 5% to 12% of global electricity use ( [[#Gelenbe--2015\|Gelenbe and Caseau 2015]] ; [[#Malmodin--2018\|Malmodin and Lundén 2018]] ; [[#Ferreboeuf--2019\|Ferreboeuf 2019]] ; [[#Diguet--2019\|Diguet and Lopez 2019]] ). According to ( [[#Ferreboeuf--2019\|Ferreboeuf 2019]] ) the annual increase of energy demand from digitalisation could be limited to 1.5% against the current 4% if sufficiency measures are adopted along the value chain.		provide useful heat for industrial and building applications.
