Well, A/C is unnecessary in Newfoundland. But although it never gets
really cold in places like St. John's, neither does it get warm enough
to do without heat.

I'm not sure that there is any really good minimum-energy location on
the east side of North America. It's hard to get out of the summer
heat and humidity, and the winters can be ferocious even where it's
hot and humid during the summer. That's what happens when you have an
entire continent upwind of you.
