I heat my two-story, not-very-efficient house with wood. I'm not in upstate NY, but not much further south in the Midwest, where we get some sub-zero weather. For firewood, I cut dead or fallen trees that need to be removed on a neighboring farm, so they're "free" (not counting the cost of saw, chains, gas, oil...). So yeah, you do have to have some timber available. But if you live in the kind of place he's talking about, there's more than enough to go around. Most of the land where I live is in crops, but there are enough trees along the creeks and in rough areas that all the people burning wood don't make a dent in them.
