Hi, musicteacher. I'm not far from you in south Jackson County. About 5 or 6 years ago I did a bit of research on this. Contacted several of our state reps and senators. Did not get even one reply to my request for help in garnering information. There's a LOT of info on the net. I eventually settled on an outside wood burner. Although it does a fantastic job in keeping this large old home warm, it does have the down side in that I'm a slave to it. No matter if the back hurts, it's raining, lots of snow, whatever, I have to feed that baby! It costs about an hour of cutting, splitting and stacking to equal a week's worth of heat. I'd do geothermal if I had to do it again. Also looked into the wing generator. I like the newer vertical bladed units that are coming together. They take much less room, and are far friendlier to the feathered friends. A great resource site is
Alternative Renewable Energy. lots of good info there.
