To drying clothes!? No, we're much more likely to dry clothes outside than Americans. They dry just fine outside even in mid October; a bit more slowly than that after that, but when I was a kid I remember washing going on the line on warm days in early December.

We do have electric tumble dryers, condenser dryers, washer dryers.

(Indeed, the progressive switch to condensers may be part of power consumption dropping.)

AFAIK The UK's climate is about equivalent to New York State.
