Nerd alert. 4 years ago I added solar panels to the studio. They have been a huge net positive, last year I replaced the gas burners with an induction stove, and this year I replaced the propane furnace for domestic hot water & radiant heat with electrical systems, today the 4 years ago anniversary they cam and too the propane tank. Next up the ICE car, but have to get another 5 years out of the current (no pun intended) vehicle.
