This is the interim report on a 2-phase project to answer three key questions: what are the existing trends in industrial process energy use; what is the technical and economic energy efficiency potential over the coming decades; and what are the barriers to uptake of energy efficiency improvements, including the question of what evidence exists that quantifies or compares barriers.
This report provides a survey of all significant evidence that contributes to answering the key questions. The next phase will identify any gaps in the overall coverage and indicate where there are opportunities for making cost-effective improvements to the evidence base.
