Line dry my clothes, regardless of rain (inside lines as well as out), unless its very cold and I don't mind using the gas dryer but to double dip and use as heater, as well as dryer.
Recently bought several solar charging units as Christmas gifts and as house accessories, so now our electronics are off grid and our neighbor's kids and nieces are off grid with their things, as well. Portable aspect of it is nice when leaving home too.
All inside lights are LEDs, but I still need to buy the old fashion, heat generating lights to provide warmth for my chicks and ducklings when I incubate.
Changed from a regular PC to a laptop. Less power and much neater.
Just sat here thinking about how much money my house is currently costing me to run and I realized the most expensive thing running was my coffee maker, and that was probably more because of the cost of running the burner at the bottom, so I ordered a used Black and Decker Thermal Coffee Maker from Amazon for $37.......12 cup. I realize it will take a while for it to pay me back, but eventually it should happen.
I use a bed warmer in all beds that humans occupy, during the winter. If we go to bed with a fire in the stove, recently fed and during the night it goes out and the house begins to cool, at least the people in bed are warm. An adult can get up early and clean and load the fire and do whatever else to quickly warm up the living areas, while children sleep in warm beds.
