The data behind this page
Nothing here is estimated from a nameplate wattage; the 607 kWh/yr is ENERGY STAR's own certified figure for this model. Ranked 128 of 639 certified dryers for running cost, the LG DLE3420* 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.
