Where this number comes from
Ranked 506 of 639 certified dryers for running cost, the LG DLGX7901E 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. The rest of what changes this number, by state rather than by model, is in the guide to why your state changes this number. The 685 kWh/yr figure is ENERGY STAR's own certification, not a wattage estimate; exact dataset IDs are on the data sources page.
