Off-the-grid (OTG) is a system and lifestyle designed to help people function without the support of remote infrastructure, such as an electrical grid. In electricity, off-grid can be stand-alone power system or microgrids typically to provide a smaller community with electricity.
Off-grid electrification is an approach to access electricity used in countries and areas with little access to electricity, due to scattered or distant population. The term off-the-grid (OTG) can refer to living in a self-sufficient manner without reliance on one or more public utilities. Namely the electrical grid. People who adopt this lifestyle are called off-gridders.
Off-the-grid homes aim to achieve autonomy; they do not rely on one or more of municipal water supply, sewer, gas, electrical power grid, or similar utility services. A common misconception is that a true off-grid house is able to operate completely independently of all traditional public utility services. Although this is not the case. The term "off the grid" traditionally refers to the electrical grid only.
