That's a huge amount! I didn't realize it was so much!
Residential use is 39% of all electrical generation.
So driers are 2.3%.
That number doesn't surprise me in the least. Residential electrical consumption is trivial if you don't include heating. So having an appliance use 5% of all home electricity seems pretty low?
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).
