Wood Mackenzie expects robotics to become a major new source of global electricity demand, adding pressure to power systems already strained by artificial intelligence data centers, Kpler said in a Tuesday note.
Global robotics electricity demand could reach 363 TWh by 2035, with industrial robots accounting for 357 TWh and humanoid robots contributing 6 TWh annually.
The industrial robot fleet currently numbers 5 million units and consumes 78 TWh of electricity annually, nearly twice London's consumption, Wood Mackenzie said.
Wood Mackenzie expects the industrial robot fleet to reach 16 million units by 2035 if its current 12% annual growth rate continues, Kpler reported.
Annual industrial robot installations increased from 200,000 in 2015 to 500,000 in 2025, while Wood Mackenzie expects yearly installations to exceed 1 million by 2032.
China drives much of the global robotics market, accounting for over 70% of annual industrial robot installations and nearly 90% of humanoid robots deployed in 2025.
China State Grid plans to spend $1 billion in 2026 to acquire 8,500 artificial intelligence-enabled autonomous robots for more than 600 specialized tasks, Kpler reported.
Humanoid robot deployments could grow at more than 90% annually from 2025 through 2035, reaching more than 10 million units with annual shipments above 4 million.
If the global humanoid robot fleet reaches 1 billion units by 2050, those machines alone could consume as much electricity as South Korea generates in 2026.
Falling costs could accelerate adoption, with average humanoid robot prices dropping 93% from 2020 to 2025 to $58,000, Wood Mackenzie said.
Unitree Robotics' G1 humanoid robot costs $16,000 and carries an estimated annual electricity cost of $82 at eight hours of daily use and a $0.14 per kilowatt-hour global average industrial tariff.
"Power constraints are becoming a real brake on robotic adoption, and that matters because labor markets in developed economies are running short of alternatives," said Robert Liew, Director, Integrated Energy Research, Wood Mackenzie.
