ENERGY COST OF 2025 DATA MOVEMENT FROM EDGE DEVICES IS UNSUSTAINABLE Edge Data Explosion Requires New Compute Model to Limit Transmission Cost Annual Data Generation (ZB) 163 154 Trapped Data 126 Available IP Bandwidth 1 Zettabyte = 1,024 Exabyte 1 Exabyte = 1,024 Petabytes 97 75 58 35 27 25 2 2018 33 2 2019 45 3 3 4 5 7 8 2020 2021 2022 2023 2024 2025 ENERGY COST OF 2025 DATA MOVEMENT ~5kWh and $0.51 of energy for each GB transmitted By reference— in 2017 the world produced 71 42 The industry can’t just keep building out network capac- ity; it is limited by the energy and economic cost of bandwidth. Using a 2012 estimate of the cost of moving a gigabyte of data from the edge to the cloud, bandwidth to move the full 163ZB in 2025 of edge-captured data would cost $92 trillion and require 835 petawatt hours of elec- tricity. This equates to 122% of global GDP ($75 trillion) and 33 times the global electricity generated in 2016. $92T 92 55 Over 95% of the data captured at the edge by these devices will remain where it is, typically far from a cloud data center. By 2025, the gap between data transmission capac- ity (8 zettabytes [ZB]) and data generated at the edge (163ZB) will rise to 154ZB.

Amazon uses a semi-trailer truck to move 100 petabytes of data to its cloud. EQUIVALENT TO 25 MINUTES OF DATA FROM PRATT & WHITNEY TURBOFAN FLEET Moving 163 zettabytes of 2025 data would take either 4.2 million years or 1.6 million semi-trailer trucks.
