One of the things I missed the most living in Europe without a dryer (this was the norm in my experience, at least when/where I lived) was a warm fluffy cotton towel fresh from the dryer. I pay 8-9 US cents per kW/h which with a 240V 20A dryer (little known fact even to people who live here, almost every house in the US has both ~240V and ~120V service) pulling 3000W in service runs me about 25-35 cents a load or closer to $1 in Germany. Worth it.
If you are "synchronously" doing laundry, ie. waiting for the load to dry, then we must admit it's slower, though this may vary with the seasons and climate of your location. But if you set it aside in the morning or evening, then go out and start your day as you normally would, you're OK.
In some cases this might mean you plan your laundry better. Eg. you start laundry when you have at least 1 set of clothes to wear for the next day, instead of when you have 0 clean clothes to wear.
I do the laundry for the house; it's about 4 loads a week for 4 people, which I mainly batch up because if I'm not paying attention to the wet laundry, it can sit in the washer and get stale. It would take more like 5 minutes to hang a load- do I hang it inside, or out of my crowded home (it's in the 4-10C range outside now), so you're talking about 20 minutes, spread throughout a day. Alternatively, I can just dump the washer load into the dryer, and come back when the dryer finishes. For a busy professional, this is huge.
