Electrical systems consume energy in the form of losses. Electrical system efficiency strives to minimize voltage and current conversion losses. The impedance in transformers, uninterruptible power supplies (UPSs), power supplies, and the wiring plan affect electrical efficiency opportunities. Using additional equipment for redundancy can also affect efficiency. 

Higher voltage distribution, UPS bypass or interactive modes, and switch-mode power supplies form the heart of electrical energy advances. Transformers have been optimized to achieve efficient low-loss performance at lower loads (below 30%). UPS system efficiencies have improved with new conversion technologies and line interactive operation modes. Reducing and/or eliminating impedance throughout the electrical system will improve efficiency and reduce energy cost.
