Over half of the electricity produced in the United States in 1986 (2574 billion kW-Hr). More than forty per-cent of this energy could be saved by complete applications of cost-effective drive system efficiency improvements. On a national scale this would: save 25 to 50 billion dollars per year and save l00 to 300 billion dollars due to delayed construction of new power plants. If suggested improvements, such as those in Energy Efficient Drivepower - An Overview, were implemented, the total cost savings could be substantial. At an average Cost of Energy Saved of 0.5 cents per kilowatt-hour (kW-h), fifteen year lifetime, five per-cent annual real discount rate, and an electrical energy cost of 5 cents per kW-h, you could be paying 4.5 cents for every kilowatt-hour saved over the fifteen year period. If you had used 1,000,000 kilowatt-hours of electrical energy in 1986 (equivalent to running five 25-HP motors continuously for a year), your potential savings could have been: between 28% x 1,000,000 kW-h x 0.045 {cents}/kW-h and 60% {times} 1,000,000 kW-h {times} 0.045 {cents}/kW-h, or between $ 12,600 and $ 27,000. Over the 15 year period, this would mean $189,000 to $405,000 saved.
