I plan to eventually put a nice PV array on the main roof, probably solar heating on the south walls (and a small ammount on the roof for summer domestic water), however my friend might convince me to do geothermal (he runs a geothermal company) or may couple a heat pump with thermal storage and solar heating.
However currently my major project for this year is replacing my septic system, will likely cost around $10-15k and will put a huge damper on what I had hoped to do this year.
My first small project is insulating a wall adjacent to my master bedroom and the attic. For whatever reason it has zero insulation. I'll start a thread for that in the next few days, should go quickly as I have already purchased the insulation
