Since electricity meets approximately 20 percent of our overall end-energy requirements, it plays a vital role in all spheres of our daily life, and is also of immense economic importance. Experts are of the opinion that there is realisable potential for electricity consumption to be reduced by around 25 percent..
The efficiency potential is particularly high in the areas of electric motors/drives and electrical and electronic appliances. At present, electric motors alone are responsible for the consumption of approximately 45 percent of electrical energy. In buildings it is primarily household systems and components (especially pumps, ventilators and lighting), and the networking of these systems, that consume large quantities of electricity.
