I hate to tell you this; but use of natural gas, propane, or electricity (from an efficient coal-fired powerplant) is way, way less pollutive than burning wood or wood pellets to cook. Not to mention the health concerns of cooking over wood on a daily basis. When you burn wood or pellets you produce particulate matter and carbon monoxide; in addition to the CO2. I would switch over to mulching or composting your stove fuel.
Well, I just had to look up what a TLUD stove was, interesting. You are probalbly right also, but no extra heat in the house is important too.
We have done much better in the boat with solar, wind and LEDs than we have in the house, and driving is a must. Do bike and walk and BBQ when we can to keep the heat out.
