Decomposition Analysis for Energy Use of SMEs In U.S. Manufacturing Industries Yadan Zeng Advisor: Dr. Chris Y. Yuan Department of Mechanical Engineering, UWM-Industrial Assessment Center This work first analyzes the energy use of small and medium size manufacturing industries in 15 industry subsectors between 2003 and Then, the logarithmic mean Divisia index method (LMDI) is used for the decomposition analysis to assess the influence of different factors on SMEs manufacturing energy use. To better understand the result of the analysis, only additive decomposition result of each year is shown.

The 15 industry subsectors is determined according to assigned Standard Industrial Classification (SIC) code. All subsectors fall in to range 2000 to Energy intensity of each sector is calculated using the equation: Energy Intensity (kWh/ unit of output) = Energy consumption (kWh) / Production (unit of output) Contact Information Yadan Zeng Share of Energy Use and Intensity in Different Subsectors in 2003 and 2014
