We are an all electric home. In 1986 we bought the place and added on in 1991 and took out the flue one brick at a time by hand since the mortar had totally failed and gave away the wood stove. The water source heat pumps have failed beyond repair so we are on resistance heat. We are planning on going with Tesla home heat pumps. Our 30 year roof is now 30 years old but well pitched so we should have some time remaining.
Fossil fuels were already under attack 30 years ago in places like CA and we have 3 phase at run a 1/4 mile past our place. I have not started planning a solar system but if they start giving them away I want one ASAP.
A new roof, ability to be off/on grid and battery storage system with Tesla heat pumps should have our big ticket items out of the way for a few decades. If we can get solar and storage at no net cost over time that would be a retirement plus. Years ago this happened for some in farming.
