I've been following this guy for a while on X. He does live this way. This isn't a hypothetical. He lives on his writing and has plenty of free time to chop all the wood he'd ever need.
Considering that the property has a well on-site, water is free, and 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.
Maybe "a little bit of electricity" or "very cheap scrap wood" appear to be the vague plans for how to handle heat.
Apparently electricity is 4c/KWh there, so it really is only a “little bit extra” even if you’re heating with resistance heat (at least for a 600sf house).
At 4 cents per 1kWh heating will not be an issue, even with regular resistive heater. It’s almost free electricity.
You could run a 1.5 kW heater 24/7 for roughly 40 USD a month. Just make sure the space is well insulated and not too large - but we’re talking about basic living, so that should be easy.
It seems like you'd need more than 1.5kW of heat in upstate new york, even for a small place (which is more than half the size of my suburban home). Also, while I agree that $40 is cheap to me, it's also an additional 10% on their budget.
Of course it’s more space than I need. My point was that heating 600sqft doesn’t strike me as a trivial task, given my context of heating a house that’s less than double the size in a temperate climate.
Not to argue (?) that their house is too small (??)
And their $30 electric budget explicitly excluded heat.
