Savings are a result, not a goal. Addressing something as fundamental as personal comfort through methods that are uncommon, difficult, or intense is Mustachian.
It seems that not many Americans understand the joy of badassity: 1) knowing and pressing your limits; 2) not blindly accepting normalized solutions. I enjoy backpacking, so I know what it feels like to be negotiating my spirit while wet and cold and hungry; I know the relief and warmth of skin to skin contact, dry socks, and warm drinks. There are other cultural mechanisms in place to allow this sacred discomfort - exercise, meditation, retreat - but it makes no sense to drive 1.5mi to the parking garage, walk to the gym, run 3mi on the treadmill, walk to the parking garage, and drive 1.5mi home. Chilling at home is a great way to stay aware of fleeting moments of deep comfort. Air squats and a 25lb dumbbell in the mid-morning sun help. It helps too to understand the sublimity of submersing in a mountain water rock pool at 6am and 45 degrees and reemerging as an exhilerated steaming animal. I will not ask my In-laws to understand, so it is likely some use of heat may occur in late Dec when they visit. I could never explain to them that contentment is far more powerful than cold: I am cold now but in my home, surrounded by food, love, and blankets; I have been cold, wet, lost, in the dark, and fretting; my soul is comfortable though my skin is chilled.
Even with one person working from home, our electricity bill hovers between $6-$8/mo for 580sqft.
