We (wife and I) have been living on a 1.3 kWh 24 v solar, 1.4 kAh of FLA batteries, and a 4 kW inverter system for almost 20 years now. Some of the things we do to conserve electricity, although some are really just trade offs where we use propane instead of electricity to accomplish the same thing.
Clothesline and power strips - yup. The only items left on 24/7 is a VHF radio which is part of the home security system along with Dakota Alerts, and a weather alert radio. On opening windows for nightime cooling, since our home's length faces south with the narrower width of it facing the prevailing winds from the west, we installed casement opening windows which help direct/scoop the breeze into the house better. Something to consider if upgrading/replacing your windows, it makes a noticeable difference.
-Stovetop/camping toaster, on the propane stove. If making more than 4 pieces of toast we use the broiler. All kitchen appliances are manual/non-electric, and no electric crock pots, fry pans, etc.
-Stovetop percolator for coffee, then use a thermos to keep it hot.
-Propane frig/freezer and chest freezer.
-Since we have a well, 1/2 HP Grundfos submersible pump, and pressure tank we conserve water as much as possible so the pump doesn't need run as much. We don't water the lawn, have rain barrels for hand watering the wife's small garden and filling the bird bath, low flow shower heads, etc. When we do run the backup generator we'll top off all the water containers and I fill five 5 gallon buckets for dog water and toilet flushing. If you've lived off grid you've probably said or heard something like "Don't flush the toilet until the sun comes up, the batteries are low and the generator will start if the pump runs" lol
-Compact fluorescent light bulbs, we got these as a housewarming gift 20 years ago before the LED ones were popular, I'll switch to LED as these die and need replacing but they never do.
-Lap top instead of desk top computer.
-Express/1-hr cycle for the dishwasher, no water temp boost or heated drying options. Larger items are hand washed.
-Use shorter clothes washer cycles, presoak really dirty clothes or wait until we have a full load for a hot water/heavy-duty cycle
-We rarely use the microwave, so little in fact that we jokingly refer to it as the 'salt&pepper shaker holder' because its primary use is just a place to set those on.
-Tile flooring, except for the bedrooms, less vacuuming.
-If the wife isn't going out she'll let her hair dry in the sun or dry it over the wood stove in the winter, God bless her.
I've probably missed a few, it's all second nature to us now and we don't even think about it much anymore. We do get some funny looks/comments when staying with on-grid friends sometimes, wetting our hands then shutting off the water while we wash them, then turning the water back on to rinse them for example. Or asking what drawer the can opener is in or how to use their coffee maker.
