State of Industrial Energy Efficiency 2026
Energy efficiency is the cheapest, fastest tonne of carbon a plant can save — and the numbers show it scaling. Global efficiency investment is rising, most industrial electricity still runs motors, and the grid feeding industry is steadily greening. This report compiles the public figures on where industrial energy efficiency stands in 2026.
Efficiency is the 'first fuel' — and investment is rising
Source: IEA — World Energy Investment 2024 (2024)
Global investment in energy efficiency across buildings, transport and industry reached about USD 660 billion in 2024 and has risen nearly 50% since 2019. On a net-zero pathway the IEA projects it needs to roughly triple to about USD 1.9 trillion by 2030 — a wide gap that translates into rising policy support and incentives for industry to cut waste before switching fuel.
Most industrial electricity goes to motor systems
Source: IEA — Motor-driven system electricity use (2023)
Electric motor-driven systems — pumps, fans, compressors and conveyors — account for roughly 70% of all electricity used by industry. That single fact is why motor-system efficiency, variable-speed control and right-sizing dominate any serious industrial electrical-efficiency programme: the kilowatt-hours are in the motor system, not in lighting or office loads.
Industry is electrifying, and the grid is greening
Source: IEA — Renewables 2025 — renewable electricity (2025)
Electricity made up about 23% of global industrial energy use in 2022, up from roughly 19% in 2010, as electrification of process heat and drives advances. At the same time, renewables reached about 32% of global electricity generation in 2024 and are projected to approach 43% by 2030 — so each unit of electricity industry uses is getting cleaner, tying efficiency and decarbonisation ever more tightly together.
FAQ
Why is energy efficiency called the 'first fuel'?
Because using less energy is usually cheaper than supplying more. Efficiency measures — better motors, heat recovery, insulation, controls — typically cost less per unit of energy saved than buying additional supply, so they are the first thing to deploy in any energy or decarbonisation plan.
What is the single biggest electrical-efficiency lever in industry?
Motor-driven systems, because they use around 70% of industrial electricity. Right-sizing motors, replacing throttling with variable-speed drives and cutting system friction around pumps and fans deliver the largest electrical savings on most sites.
