What this adds up to over time

Where this number comes from
Ranked 10 of 639 certified dryers for running cost, the Miele TWF160 WP 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 133 kWh/yr figure is ENERGY STAR's own certification, not a wattage estimate; exact dataset IDs are on the data sources page.
