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?
space heating: 15.2%
water heating: 11.6%
refrigeration: 7.1%
lightning: 3.9%
television: 3.7%
computer: 2.4%
other: 40.7%

I heat my house so that I can run a freezer inside the heated house to lower the temperature back down to what it is outside sometimes. It's not entirely efficient.
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).
