The U.S. Department of Energy (DOE) has initiated an effort to consider amending its energy conservation standards for battery chargers. DOE is obligated to review its energy conservation standards once every six years under 42 U.S.C. 6295(m) and to determine whether to amend its standards, or whether its existing standards do not need to be amended. To this end, DOE must determine whether national standards more stringent than those currently in place would result in a significant amount of energy savings and whether such amended national standards would be technologically feasible and economically justified. In its proposal, DOE has tentatively concluded that the proposed standards represent the maximum improvement in energy efficiency that is technologically feasible and economically justified, and would result in the significant conservation of energy. Specifically, with regards to technological feasibility, products achieving these standard levels are already commercially available for all product classes covered by this proposal. As for economic justification, DOE’s analysis shows that the benefits of the proposed standard exceed the burdens of the proposed standards.
