The figure is residential use. But sure, some commercial use would be dryers, but I assume compared to say aluminum ore electrolysis, it's pretty low.

I do not think I have ever seen an electric commercial dryer (hotels/laundromat/etc). The electric costs would be insane in comparison to gas.

Here's one: https://unimac.com/product/tumble-dryers/industrial-tumble-d...

Bigger than that goes to gas or steam only.

Note that if you're using that, you'd use an extractor, also (big centrifuge that spins the clothes so fast you can enrich uranium with it).
