LG WM6700H*A
The LG WM6700H*A is certified at 105 kWh per year over the DOE test's 234 annual cycles, which comes to about $20 a year — call it 8¢ every time you run it. Efficiency-wise it's unremarkable in a good way: within 5% of the median certified clothes washer (rank 143 of 338). The same unit costs $13 a year in North Dakota but $49 in Hawaii — electricity rates, not the appliance, make the difference. It also meets ENERGY STAR's stricter “Most Efficient” criteria. Electricity is only part of the story for a clothes washer — check the water figure in the specs below.
