The quickly increasing world robotics trade may require 363 TWh of electrical energy yearly by 2035 – equal to the yearly consumption of round 35 million common US households – in response to new analysis from Wood Mackenzie.
The discovering arrives as vitality capability planning is already underneath strain from AI knowledge centres, making robotics a second and largely unmodelled demand on world electrical energy infrastructure.
Wooden Mackenzie places mixed robotics energy consumption at 363 TWh by 2035, with industrial robots accounting for 357 TWh within the higher vary and humanoid robots including an extra 6 TWh yearly.
The economic robotic market’s progress by 2035 is drawing energy and approaching knowledge centre scale. The 5 million robots in operation at the moment eat 78 TWh a yr, nearly twice London’s electrical energy consumption.
Wooden Mackenzie expects the operational fleet to succeed in 16 million models by 2035, if it could actually preserve the present tempo of enlargement at 12 p.c a yr.
No single nation shapes this market greater than China. It accounts for over 70 p.c of annual world industrial robotic installations, and Chinese language corporations are accountable for practically 90 p.c of all humanoid models at the moment in deployment.
China State Grid illustrates that place immediately: it’s spending $1 billion in 2026 to purchase 8,500 AI-enabled autonomous robots for greater than 600 specialised duties, from routine grid upkeep to live-line work on ultra-high voltage energy strains.
Humanoid robots are nonetheless early in rollout however rising quick. If the worldwide market reaches one billion models by 2050, energy demand from humanoid robots alone may match South Korea’s complete electrical energy technology in 2026.
More and more aggressive costs are pulling extra consumers in. Common humanoid robotic costs fell 93 p.c between 2020 and 2025 to $58,000.
China’s Unitree Robotics’ G1 is now priced at $16,000, with an estimated annual electrical energy value of $82 per unit at eight hours a day (primarily based on a world common industrial tariff of $0.14 per kWh.), considerably under human labour prices in most markets regardless of it being largely utilized in restricted settings.
Robert Liew, director, built-in vitality analysis, Wooden Mackenzie, says: “Energy constraints have gotten an actual brake on robotic adoption, and that issues as a result of labour markets in developed economies are working in need of options.
“Industrial robots already draw 78 TWh a yr globally, and that’s earlier than humanoid robots attain any actual scale. By 2035, mixed demand may hit 363 TWh.”
Key findings
- Mixed world robotics electrical energy demand reaches 363 TWh by 2035 (Wooden Mackenzie base case), approaching France’s nuclear technology of 373 TWh in 2025. Industrial robots account for 357 TWh with humanoid robots contributing 6 TWh yearly. Each figures compound AI knowledge centre demand already stretching world energy infrastructure.
- The 5 million industrial robots working in 2025 draw 78 TWh yearly, equal to 20-25 p.c of worldwide knowledge centre demand; the fleet reaches 16 million models by 2035 assuming 12 p.c CAGR development is maintained. Annual installations grew from 200,000 (2015) to 500,000 (2025) and are forecast to exceed 1 million by 2032. (Supply: Worldwide Federation of Robotics, Wooden Mackenzie)
- Humanoid robotic inventory grows at over 90 p.c compound annual progress fee from 2025 to 2035, reaching 10 million+ models with annual shipments exceeding 4 million; common unit worth fell 93 p.c between 2020 and 2025 to $58,000. Unitree G1 (2026 worth: $16,000) carries an estimated annual electrical energy value of $82 at eight hours a day, primarily based on a world common industrial tariff of $0.14/kWh. (Supply: Unitree, Wooden Mackenzie)
- China accounts for over 70 p.c of annual world industrial robotic installations and practically 90 p.c of all humanoid models deployed in 2025. China State Grid has dedicated $1 billion in 2026 to obtain 8,500 AI-enabled autonomous robots throughout greater than 600 specialised duties, signalling that robotics has change into crucial nationwide infrastructure.
Rising demand
Robotics demand has grown for over a decade, pushed by structural labour shortages, rising labour prices, and provide chain safety issues. AI advances in laptop imaginative and prescient, giant language fashions, and reinforcement studying have prolonged robotic functionality into logistics, healthcare, and subject operations.
Most industrial robots draw energy immediately from the native grid, with out low-carbon sourcing mandates. Robotics coaching infrastructure is captured inside knowledge centre demand estimates and excluded right here to keep away from double counting.
