No mention of heat pump air dryers? They save considerable amounts of energy. Probably not enough to make up for the increased costs, though -- AFAICT most people install them because they don't require a vent outdoors.

It also depends on the weather where you live. Unless you don&#x27;t mind clothes that smell funny.<p>In Japan they don&#x27;t commonly use dryers and mostly hang dry everything (except maybe Okinawa where I guess it&#x27;s too tropical). But their bathrooms as set up to operate as a big dryer. You dry both your clothes and the bathroom itself.

Many townships make line drying illegal, at least in PA.

I recently unplugged my dryer and stopped using it, but for a dumb reason: I moved it for cleaning, the dryer vent detached itself, and there&#x27;s not enough space to reattach it without moving the washing machine.<p>Previously I was already line-drying over half of my clothes. Dryers add additional wear, can shrink or deform items, and a lot of my clothing is synthetic or wool. The cost savings was a bonus, since the dryer is already there and fed by gas. There&#x27;s a drying rack in the corner of my home that just never goes away. Some items come out rough like towels, and things that need ironing with a dryer need even more ironing when line dried. But it&#x27;s rare that I need an article of clothing that can&#x27;t wait overnight to be line-dried.

I wonder how ultrasonic dryers have been doing lately. I don&#x27;t know anything about them, but heard about them at an ARPA-E conference a while back. Don&#x27;t know if this is still very low TRL, or just massively too expensive, or really doesn&#x27;t work all that well. But they are supposed to be much more electrically efficient.<p><a href="https:&#x2F;&#x2F;www.energy.gov&#x2F;eere&#x2F;articles&#x2F;no-heat-no-problem-ultrasonic-dryer-dries-clothes-half-time" rel="nofollow">https:&#x2F;&#x2F;www.energy.gov&#x2F;eere&#x2F;articles&#x2F;no-heat-no-problem-ultr...</a>

&gt; Over the lifetime of a dryer, 100% line drying could save a household upwards of $2,100. That would also cut back CO2 emissions by more than 3 tons per household over the same time. Though the contrast between dryers and line drying is stark, it’s not surprising, the researchers said.<p>Sad to say, I know people who&#x27;ve spent well over $2,100 on the dryer itself. (Initial purchase, then repairs.)

It is too bad many Cities made it illegal to hang cloths. I use to do that years ago, but now you get fined.<p>So instead we use the dryers and toss chemical sheets in the dryer to give the cloths a &#x27;fresh smell&#x27;. Time to repeal those laws.

I have an electric clothes dryer in my apartment, but growing up my family always had natural gas-powered dryers. Even when my parents added a washer&#x2F;dryer to their bathroom, they ran a new gas line for it.

There&#x27;s got to be some health benefit to having clean dry clothes and towels.

There’s no benefit to a clothes dryer.<p>They cost money, take space, ruin your clothes, are bad for the environment.
