(i) Workloads assumed to increase ten-fold by 2030 (European Commission 2015), consistent with Cisco (2018), and Andrae and Edler (2015). (ii) Counterfactual scenario assuming that energy/workload remains unchanged. (iii) Andrae and Edler assumed that efficiency gains according to Moore’s Law would slow down considerably after 2020. (iv) Both European Commission (2015) scenarios assume that efficiency gains according to Moore’s Law continues until 2030. (v) “Frozen PUE efficiency” means PUE = 2.0. Computation efficiency assumed to increase according to Moore’s law
