Smaller capacity washers will have better energy-efficiency ratings, but the smaller capacity may mean that you have to run the machine more often, and it may cost you more to operate. Refrigerators and Freezers Consider what style and features you want in the new refrigerator and what the energy consequences might be. Bottom freezer models are slightly more efficient than top freezer models. Manual defrost models use less electricity than automatic defrost models, but beware, manual defrost models must be defrosted periodically to maintain their efficiency. Also consider size when shopping for a refrigerator.
Larger units use more electricity and take up more space.
Currently, the most efficient models are in the most popular 16-20 cubic feet range. Models that are equipped with ice makers and water dispensers will have a higher energy use. Copyright 2000 Enercom, Inc .
