'Factor 5' Solutions: Super-refrigerators

In the 70's, the average refrigerator consumed 3.36 kWh/yr per liter volume, but refrigerators nowadays achieve much better performance (for example, see Certified Environmental Product Declaration ER 8117B achieving 1.15). Despite this improvement of a factor 3, there is potential to achieve 0.26, almost 5 times better.
