New electronic washers by Staber, Whirlpool, Frigidaire and Maytag Neptune use much less power, less water, less soap. Some of them require a sine wave inverter, will not run on a generator, and void their warranty when used with generator or inverter power. Staber, listed in this catalog, uses only 160 watts-hours per load, does not need sine wave power, and the factory is happy to sell to renewable energy users. Staber can really save energy if you do a lot of laundry. AC Propane heated clothes driers can be used, but try to get one with a pilot light, not electric glow-bar ignition.
Electric stoves are out.
Propane or natural gas stoves with gas pilot light need no power connection at all. Spark ignition burners use very little power and work fine with inverters. Do not buy a gas range with electric glow bar as oven pilot light. Instead, look for one of two types of pilot light oven. An oven with regular gas flame pilot light is the simplest.
