A brochure on efficient use of energy in manufacturing processes in industry was published in 2004 by Bavarian environment agency (LFU). With its catchy title ‘Protect Climate – Reduce Costs’ (German: ‘Klima schützen – Kosten senken’) the brochure targets at small and medium sized companies and aims to raise conciousness about energy efficiency in different areas of a manufacturing company such as pressurized air, air condition, heating/cooling, lighting and others.

On page 6 this Sankey diagram shows an overview of energy flows in the company…

… and on page 7 a detailed view of a process section (extruder, corrugator, spray bath)

The first diagram is in percent of the total energy consumption, directing the interest to the areas that contribute most to energy consumption, losses (and energy costs) in the company. In the second diagram the unit is kW.

Thanks to the blog reader who sent in the brochure and helped out in translating from German.
