The Department of Energy (the federal agency that sets efficiency rules for appliances and equipment) had created new rules requiring walk-in coolers and freezers — the kind used by grocery stores, restaurants, and warehouses — to use less energy, with manufacturers needing to comply by 2027 and 2028. This resolution cancels those new efficiency rules before they take effect, meaning businesses that buy or make these walk-in coolers and freezers won't be required to meet the stricter energy-saving standards the Department of Energy had planned to phase in.
