The article discusses how we can use energy more efficiently to save resources and money. It explains that the European Union has rules to help use energy wisely. By combining energy efficiency with good energy management in companies, we can see the best results. The study shows that just basic comparisons won't save as much energy as we could. But if we carefully manage how we use energy alongside efficiency measures, we can run factories using less power for each thing we make. This way, we can save more energy and run things more eco-friendly.
