통신 네트워크 에너지 효율은 연간 12% 상승 : 소비 에너지 1MWh 당 트래픽은 2020년 12.3TB에서 2022년에는 15.5TB에 도달, 비용 절감과 배기가스 제어에는 효율화가 필수적

For a group of 16 telcos, MTN Consulting has analyzed data on network traffic, energy consumption, carbon emissions, and revenues. This brief examines the relationship between energy consumption and network traffic in the telco market.

The group of 16 telcos included in this analysis represent over 40% of the global market, based on revenues. On a revenue basis, our data verify the well-known revenue-traffic conundrum: in 2022, the average telco carried 1.93 Petabytes of traffic per US$1M in revenue, up 37% from 1.41 PB/$M in 2020. In the 2020-22 timeframe, this group increased network traffic at an average annual rate (CAGR) of 13.8%, while their total energy consumption grew at a CAGR of 1.2%. As such, in 2022 the average telco consumed 64.4 MWh of energy per Petabyte of traffic, down from 81.3 MWh/PB in 2020. This improvement is in line with the stated goal of both telcos and their vendors: to improve the network's energy efficiency over time. The average telco's carbon footprint per unit of traffic also declined in the same period, from 110.8 millions of tons of CO2 equivalent (MTCO2e) per Petabyte in 2020 to 83.3 MTCO2e/PB in 2022.

Telco sustainability reports emphasize the importance of adopting energy efficient technologies and network designs. Vendors consider the energy efficiency of their solutions a crucial differentiator. As telcos attempt to lower energy costs and reduce their carbon footprints, vendors have an opportunity to support further improvements.
