Where this number comes from
Nothing here is estimated from a nameplate wattage; the 685 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 475 of 639 certified dryers for running cost, the LG DLG7151* is also worth reading with a caveat specific to this category: the methodology page explains why ENERGY STAR's own combined-energy figure for dryers can overstate the electric bill impact of a gas model.
