Dec 30, 2010 at 17:01 comment added Bob Roberts The energy calculator was wonderful. With it I roughed out about $20 per million btu for electric, $70 per million btu for propane. Geothermal is out because I don't own the land under me and I don't plan on being there long enough to recoup solar (solar electric) nor do I want to put holes in my roof/wall for additional duct work (solar heat).
