We've had this debate before
So am not going down that road again...
United States is a vast country and energy prices vary very much by geographical location.
Here in New York electricity rates are dear: Con Edison is currently 21.0 cents per kilowatt hour, and natural gas is gas, at $1.262 per therm.
Most here use natural gas for cooking, water, home heating and clothes dryers. Things may vary by type of home (older apartment buildings still largely burn oil for heat/hot water for instance).
Con Edison and other utility companies in this state also tack on a vast and bewildering array of taxes and surcharges mandated by local government.
All this being said when most go dryer shopping here first and foremost the decision is based upon what fuel (gas, propane, electricity) is available.
Con Edison has a nifty tool to promote "energy efficient" appliances.
"CLEARCOST shows you what this product may cost you to buy and run. CLEARCOST is worked out by combining the lowest available purchase price for the product that day from retailers shown on Con Edison Marketplace, with the energy costs of using the product over its typical lifetime, with the electricity rate specified, and the typical amount of usage."
Several heat pump dryers dominate the top rankings with a "100" score. However the details tell another story.
Whirlpool WED9290FC - Has a total cost to own and run for 16 years of $4,267

Miele TWF160WP - Is slightly better at $2,163 for same period only because of lower energy use.

Kenmore Elite 61553 (vented) comes in at $3,982 with a bulk of that cost coming in energy usage.

You can see anyway sliced electric dryers are expensive here, but there is another consideration.
Many simply do not want to wait two or more hours for a load of laundry to dry. This is the same complaints many north Americans have about European laundry appliances in general; they take too long.
