maybe you could compare the european and us standards.
www.topten.ch (german). klick on "haushalt/kühlschränke"
the most efficient at "16-38c" ambient temp is the candy cpdc 320aa plus,
with a 253 l (8.9ft^3) combined fridge/freezer cap and a 203 kwh/year
consumption, ie 22.7 kwh/ft^3-year, or 7.9 kwh/ft^2-year.
i like the heat pump clothes dryers and drying closets. the hot air dryers
also look more efficient, at about 0.3 kwh/kg, with a 5-6 hour drying time.
the horizontal-axis washers also take longer, use less water and soap and
energy, and heat their own water. how much of this stuff would run on our
240 v 60 vs 50 hz?
