The U.S. Department of Energy (DoE) estimates that over 100 billion kWh can be saved every year in the United States by using power electronics motor drives. At $0.10/kWh energy cost, that would save about $10 billion per year and would eliminate about eleven 1000-MW power plants in the country. A significant fraction of electrical power in the United States is already supplied through power electronics and perhaps higher in other countries where the energy cost is higher.
