i could be wrong but seems to me most houses are built from pine studs (not a hardwood)and most us are burning hardwood pellets unless there are areas that use oak and other hardwoods for framing out a houses. and has there been that much waste from the cabinet makers to supply us with pellets for all those years.i just dont understan how the can just blame it on the housing market .sound like the politicians might be buying stock in the pellet mills
