The U.S. Department of Energy (DOE) determined that more stringent energy conservation standards for small electric motors (SEMs) are not cost-effective, so existing standards will remain unchanged. The analysis by DOE found that while technically feasible improvements exist for SEMs, the costs of implementing them would outweigh the energy savings benefits for consumers. As a result, the standards set by the Energy Policy and Conservation Act (EPCA) will not be amended because they would not be economically justified. This decision concludes that the potential energy conservation from new standards would not meet significant conservation thresholds under the current criteria.
Simple Explanation
The U.S. Department of Energy decided not to change the rules for saving energy with small electric motors because making changes would cost too much money compared to the energy saved.
