Energy Savings and the Reduction in the Emission of Greenhouse Gases Resulting From the Use of Foam Plastic Insulation in Refrigerators and Freezers. A Lifecycle Analysis
The paper presents a case study of the use of foam plastic insulation in refrigerators and freezers from the perspective of the reduction in energy consumption and greenhouse gas emissions when compared to insulating materials once used in refrigerators and freezers.The analysis considers the energy consumption and greenhouse gas emissions of the manufacture of each insulation as well as the consumption of energy and emissions during the operation of the appliances. The results are presented in terms of energy savings and carbon dioxide equivalents of greenhouse gas emissions avoided annually per appliance. Annual savings for the United States are also given. In addition savings are expressed over the expected lifetime of the units and time to payback the energy used and emissions produced in the manufacture of the plastic insulation are given.
