S. 5338
# Summary This bill restricts the Department of Energy's authority to establish new energy efficiency standards for consumer products and commercial equipment. The legislation requires that any new or amended energy standard must be both technologically feasible and economically justified, and it raises the bar for what qualifies as "significant energy savings" to a ten percent reduction in energy use over thirty years. The bill also extends the timeline for manufacturers to comply with new standards from three to at least six years and prevents the Department from issuing new standards for distribution transformers. Additionally, the legislation preempts state and local governments from imposing their own energy efficiency standards or restricting products based on fuel type, ensuring uniform national standards. The Department must issue updated procedural rules within 270 days of enactment, and if it fails to do so, recent energy conservation standards for furnaces and commercial water heating equipment will be voided.
