Energy Intensity — definition
Ratio of total energy consumed to a unit of output, such as kilowatt-hours per tonne produced, used to benchmark and track process energy efficiency.
Energy intensity normalises energy consumption for production volume, allowing comparison across periods, lines or facilities of different sizes. It is a common metric in cold chain, feed milling and food processing operations where refrigeration, drying or extrusion are major energy consumers.
Why it matters to industrial buyers
Tracking energy intensity supports both operating cost control and disclosure requirements linked to sustainability reporting and decarbonisation targets.
Key reference points
Common unit
kWh per tonne of output, or kWh per cubic metre of stored product in cold storage.
Major driver
Refrigeration, thermal processing and compressed air are frequently the largest contributors in food and feed plants.
Commonly confused with
Utility consumption
Utility consumption is an absolute total figure; energy intensity is normalised per unit of output, enabling fair comparison over time.
How it is used in practice
The energy audit reported energy intensity of 145 kWh per tonne, which the plant used as the baseline for a decarbonisation programme.
Frequently asked questions
Does energy intensity account for production mix?
It should be adjusted or segmented by product type where mix varies significantly, since some products are inherently more energy-intensive.
Is lower energy intensity always achievable through automation?
Not always; process design, insulation and thermal recovery often contribute more than automation alone.
