Power here comes largely from nuclear, wind, and solar sources now. My concerns about burning more wood than necessary include both carbon dioxide and particulate output. In fact, one of my horses has heaves and can be seriously bothered by woodsmoke at times.

You are right that we are using a renewable resource when we burn wood, but that's only true if we are conservative about our use. If everyone started burning wood more, our forest resources would collapse quickly. Here we have plenty in our own woodlot, it's true, and in fact the oaks have been dying off faster than we can use them up. But it takes a lot of energy to cut up a large tree and split it down to pieces to fit the woodstove too. (And at my age, doing it all with a bucksaw and a maul with wedges is, well, unlikely to impossible.)

We maintain the stove and a woodpile as a hedge against power failures, which still happen frequently enough here, and at inconvenient times like winter ice storms, to require some plans. Our main heating and cooling runs on electricity, but uses a geothermal resource for both heat and air conditioning, which does cut the power usage considerably as long as the power is on at all.
