Saving energy in companies is essential for a number of reasons. This was particularly evident due to the geopolitical crises, which drove industrial electricity prices in Germany to record levels in 2022 (Statista, 2024). They have shown that saving energy is becoming increasingly important for the competitiveness of companies. Energy consumption is one of the biggest cost factors, particularly in manufacturing companies. Companies that reduce their energy consumption can sustainably reduce their operating costs and thus increase their profit margins. This gives them a clear advantage over competitors who continue to bear high energy costs. In addition, energy-efficient companies are better prepared for price fluctuations caused by crises and are less affected by rising energy costs. They benefit from both financial stability and planning security.
