Where this number comes from
Two sourced numbers, nothing modeled: ENERGY STAR's certified kWh/yr for this exact model, and EIA's published state electricity rate. Ranked 35 of 639 certified dryers for running cost, the Smeg DH24UWH 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.
