The Department of Energy — the federal agency that sets efficiency rules for appliances like washing machines, dishwashers, and commercial air conditioning units — issued a rule in October 2024 updating how manufacturers must test, certify, and label these products for energy use, plus how the government checks that companies are following the rules. This resolution would cancel that update entirely, meaning the older certification, labeling, and enforcement requirements would stay in place instead. If you make, sell, or buy appliances covered by these rules, this determines which set of paperwork and testing standards manufacturers have to follow and how the government verifies their claims about energy efficiency.
