> as far as heat goes, well, one could either pay a little extra in electric for that — or they could have the Amish deliver their scrap wood from their sawmills to burn in a wood stove, very cheaply.
That's it. The line in the budget for heat is there and was left intentionally blank:
> Heat:
You can't just hand-wave away the cost of electric heating at the temperatures they get in upstate NY, even if the 0.04 number is accurate year-round (which it almost certainly isn't), and wood-burning stoves use way more wood than the author appears to be imagining with their "scrap wood" comment.

Kinda like those people that got free _waste_ oil from restaurants to run their vans. It's not something you can replicate literally anywhere but it does exist. Industrial waste has to be disposed of somehow and often people are happy for you to accept it for free.
