Telefónica says total energy consumption fell 12% between 2015 and 2025 while data traffic rose twelvefold. The company reports that energy use per petabyte of traffic is now 29 MWh, 92% below its 2015 level. The signal for telecom operators is that fibre migration, 5G rollout, automation and AI-supported infrastructure management are becoming operating-cost tools as well as sustainability measures.

- Traffic rose twelvefold while energy intensity fell 92% since 2015
- Fibre, 5G and AI are turning efficiency into cost control
The fact
Telefónica says its total energy consumption fell 12% between 2015 and 2025, even as data traffic across its networks increased twelvefold. The Spanish operator now uses 29 MWh of energy per petabyte of traffic, 92% below its 2015 level. It links the improvement to fibre migration, 5G rollout, automation, AI-supported infrastructure management, renewable energy use in main markets and legacy network switch-offs.
The Assessment
The signal is that telecoms energy efficiency is moving from ESG messaging into core network economics. Telefónica is using fibre, 5G and intelligent operations to absorb traffic growth without matching energy growth. That matters for operators facing power-price volatility, heavier data demand and regulatory pressure on emissions. It also strengthens the case for retiring copper and older mobile infrastructure where energy costs are becoming harder to justify.
What to Watch
Watch whether Telefónica reaches its 95% energy-intensity improvement target by 2030, and whether Scope 3 cuts begin to reshape supplier selection, equipment replacement and procurement rules.
