What are you doing to fight climate change? I bought an earth bermed home in a cool climate but that might not even be enough if the talk about climate change is real. I am considering putting the entire home deep under ground correctly as the underground temperature is about 50F year-round vs. the -25F to +90F swing throughout the year. That means I can make up the 15 degree difference using sparse solar heating and heat batteries. The biggest challenge is the cost of steel and high pressure concrete right now is quite high and finding reliable contractors in a very rural area is not easy. I may end up just doing it myself knowing I will miss out on many tricks of the trade.
