EERE Success Story—New Advanced Refrigeration Technology Provides Clean Energy, Low Utility Bills for Supermarkets

Traditional supermarket refrigeration systems found in most U.S. grocery stores require a substantial amount of energy to keep fruits and vegetables fresh year round. An average supermarket consumes nearly 2 million kilowatt hours per year, and refrigeration accounts for nearly half of that. They are also prone to significant refrigerant leakage—20 to 25% leakage a year of the two to four thousand pound refrigerant inventory—emitting environmentally harmful greenhouse gases into the atmosphere.
