Buying an Energy-Efficient Electric Motor

for a continuously operating 50-hp motor with a 75% load factor saves 4079 kWh, or $163 annually. Thus, an energy-efficient motor that offers four points of efficiency gain can cost up to $1,304 more than a standard model and still meet a 2-year simple payback criterion. A utility rebate program would
