I can't speak for everyone, but generally speaking, a lot of the heating methods the Mid-Atlantic uses, like heat pumps and electrical systems, aren't as popular or effective in actual cold-weather climates. Most northern climates use natural or propane gas for heating. Not cheap, but arguably cheaper than electrical heating that's frequent in the MD-type areas.
It's also somewhat of a trade off. Higher heating costs in the Winter for lower cooling costs in the Summer. You go into places in the Northeast, where winters are rough, and they don't really do central Air Conditioning.
I live in VA, which is a milder climate. We get 90-100 degrees plus humidity in the Summer and 20-30 degrees in the Winter. I spend significantly more $ to cool my house than to heat it.
If you want real comedy, check out like London area. They have mild summers. When it gets to like 80-85 degrees outside, they think it's the end of the World. Air conditioning is very rare over there. Most areas of the US 80-85 highs is windows open, let the breeze fill the air days.
