I have 10 acres of hardwoods that I bought 30 years ago. I’ve cut firewood on it every year. Usually between 4 to 6 cords. I’ve also logged off the softwood twice in that time. There is now much more wood on that land than when I started. As far as it being sustainable and carbon neutral here is an article about this. https://www.mprnews.org/story/2019/11/09/climate-curious-is-burning-wood-for-heat-carbon-neutral. In the late 1800s Vermont was largely deforested because of over harvesting. Much of the forest was simply burned down to make pasture for livestock. Wasted, in other words. Now the opposite is true. I agree that if everyone used wood to heat with and didn’t manage the forest properly then it would become deforested. I never said everyone should burn wood but only that for me it makes sense. Most people around me burn wood for part of their heat and the forest keeps growing. Many people who don’t burn wood do so because it is labor intensive. I get that, believe me. The good thing is the amount of labor required to cut a cord of wood stays the same. Price of other fuels fluctuates wildly and sends huge amounts of money into the hands of utility conglomerates and in some cases foreign governments that do not have our best interests at heart. I prefer to not give my money to the Saudi Arabians or Shell oil if I don’t have to. If you live in areas that are not forested than burning wood makes less sense.
