The Department of Energy (DOE) has proposed energy efficiency rules for commercial refrigeration equipment and walk-in coolers and freezers. According to an analysis by the DOE, the proposed rule for commercial refrigeration equipment should reduce energy bills by up to $4 billion over 30 years and the rule for walk-in coolers should save an estimated $24 billion over the 30 year period. In total, the two rules should save $28 billion and reduce carbon dioxide emissions by over 350 million tons. Both rules will be open to public comment for 60 days once the rules are published in the Federal Register. Each rule will also have a public meeting. The meeting for the commercial refrigeration rule is October 3 and the meeting for the walk-in coolers and freezers rule is October 9.
