I think firewood is just dying out as a heating source, as it just cannot compete in the modern world.
I used to sell a lot of firewood, but that is no longer the case. There are just too many things going against it, from the greenies thinking cutting wood is bad, with an agenda that is filtering down to our kids in school, to minisplits providing heat at a cheaper cost.
Then you add in the demise of the American Family, where most families are blended and so weekends often mean shuttling kids to and fro from ex-spouses houses for weekend visits...the demographics who would benefit from cheap heat the most, are too busy to do the work that is firewood.
And work it is, and that is not in vogue today to say the least.
Then there is the cost, my property taxes jumped 40% last year alone, when you calculate in what maintaining a woodlot actually costs, against natural gas, oil, and other fuels, its not exactly cheap. Neither is homeowners insurance who get a higher rate for heating with wood. And forget about wood if you are a foster home or day care center: there is NO WAY you are going to get the place approved by the State Fire Marshall.
And then there is travel. With firewood you are stuck home in the winter, and as a rule today, American's like to travel. They want the set it, and forget lifestyle of other types of heat.
Myself, I have log trailers, skidders, chainsaws, grapple skidders, feller-bunchers and the like...the most forestry equipment I have ever had, and hundreds of acres to gather firewood, and I heat with wood pellets. Yep, I do. I can go out in the woods, cut a load of tree length hardwood pulp, take the money, and buy pellets to heat my home for a year. No bucking, splitting, hauling, stacking, or mess inside the house. In a single day I can fell, limb, twitch and still be warm all winter.
I am not saying firewood is bad type of heat, it just can no longer compete in this modern world. Lifestyles, along with other forms of heat have just crowded it out.
