—This paper analyzes changes in energy intensity in
the manufacturing sector in Thailand during 1991-2013, using
the logarithmic mean Divisia index in multiplicative form.
Results show that energy intensity in the manufacturing sector
improved during this 22-year period, especially in the food &
beverage, chemical, and unclassified sub-sectors; sub-sectors
that did not show improvements were the fabricated metal,
wood & furniture, textile, paper, non-metallic metal, and basic
metal sub-sectors. Computational results show that energy
consumption in the manufacturing sector increased
significantly during 1991-2013 mainly on account of production
effects, but that structural effects and intensity effects
contributed only marginally to changes in energy consumption.
The findings imply the need to balance restructuring policies
within the manufacturing sector with efforts to reduce energy
intensity, so as to attain sustainable economic development and
improvements in energy efficiency, in accordance with
Thailand’s long-term energy efficiency goals.
