• Depends on type of raw material and expected product output
![Page 33: Introduction to Energy Efficiency, Approach and Working Steps](https://reader030.vdocuments.mx/reader030/viewer/2022033103/56814495550346895db1366b/html5/thumbnails/33.jpg)
PRODUCTION PROCESSES
• Different methods available (for spinning, weaving, dyeing, printing etc.)
• Uses large quantity of electricity and fuel
• Electricity or fuel depends on type of industry
