A Report on Global Warming and Energy Consumption Trends of Major Appliances

摘要

Energy and global warming indices for ten major appliances have been examined. A two-pagesummary report for each appliance category has been written as well as a combinedsummary for major appliances. The appliances studied are: refrigerators, room airconditioners (RACs), freezers, gas ranges, electric ranges, microwave ovens, clotheswashers, gas dryers, electric dryers, and dishwashers. This report contains copies of thesummary reports, bibliographical data, assumptions, and data tables developed by thisinvestigation. Computational spreadsheets have been developed that allows new data tobe easily incorporated for future reports.In general terms, most major appliance categories have reduced energy requirements overthe past two decades. At the same time, increased appliance production causes overallenergy demand and global warming effects to remain relatively constant. "Direct" globalwarming effects decrease significantly after the year 2010 as appliances using chlorinatedrefrigerants (primarily R11 and R12) are scrapped.
