Although you might not necessarily need electricity in your off-grid house, it will certainly make it more comfortable. To become energy-independent you can generate electrical power with renewable sources. The most common are solar, wind, hydro and geothermal.
Most off-grid electrical systems will typically include a deep-cycle battery or/and a power generator. They will provide you with power when there is not sufficient energy available from a renewable source.
For example, solar panels can be incredibly useful, but they cannot work at night and on cloudy or winter days will give you only a fraction of their maximum output. The same goes for wind turbines, which need a steady wind to work at their best.
Water can be obtained from several sources, such as a river or stream, lake, water well or a tank. In addition you can collect rainwater for later use. In each case you might want to use a water filter or purifier.
Off-gridders are not connected to a sewer system, opting instead to use dry toilets or composting toilets.
A greywater system an be used to recycle the water used in kitchen and bathroom. You can use it in toilet or in irrigation.
