Analysis reports significant energy efficiency improvements in non-energy-intensive industries, suggesting greater potential for decarbonisation.

Assess the energy efficiency potential in non-energy-intensive manufacturing industries using on-site evaluations.
Conducted 106 standardized, on-site energy assessments from 2015 to 2024.
Analyzed technology-based energy use compared to the best available technology.
Grouped identified potentials into categories for comparison with existing literature.
Average potential for economic energy efficiency improvement was 17%.
Equivalent to 303 GWh per year of energy savings across audited sites.
Heat recovery contributed 4.2 percentage points, and process optimization contributed 3.8 percentage points.

Marx et al. (2026) studied this question.
