For years, the industrial sector has been involved in energy saving and efficiency plans after carrying out energy audit processes, mainly due to the significant impact of energy costs on production costs, which in some cases can account for between 25% and 50% of total costs. Additionally, it should be noted that energy efficiency measures have traditionally been less widely implemented in small and medium-sized industries, making it necessary to focus efforts on this business segment.
Regarding consumption typologies, in general the most significant are lighting, which represents an average of 10% of energy consumption, air conditioning and climate control at 25%, and machinery at 65%. There is a wide variety of industrial processes, each with its own associated consumption patterns.
As for efficiency technologies in the industrial sector, it is worth highlighting that there is a wide range of solutions, all of them adaptable to the different industrial processes mentioned above. Some of the most relevant include:
- High-efficiency motors, with savings of up to 10%.
- Variable speed drives, with savings of up to 25%.
- Air compressor improvements, with savings of up to 30%.
- Heat pump improvements, with savings of approximately 40%.
