Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewerage, sewers, electrical grids, and telecommunications (including Internet access, Internet connectivity and Broadband, broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing Commodity, commodities and services essential to enable, sustain, or enhance societal quality of life, living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to Climate change mitigation, mitigate and Climate change adaptation, adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and gre ...

Single-wire Earth Return
Single-wire earth return (SWER) or single-wire ground return is a single-wire transmission line which supplies single-phase electric power from an electrical grid to remote areas at lowest cost. Its distinguishing feature is that the earth (or sometimes a body of water) is used as the return path for the current, to avoid the need for a second wire (or '' neutral wire'') to act as a return path. Single-wire earth return is principally used for rural electrification, but also finds use for larger isolated loads such as water pumps. It is also used for high-voltage direct current over submarine power cables. Electric single-phase railway traction, such as light rail, uses a very similar system. It uses resistors to earth to reduce hazards from rail voltages, but the primary return currents are through the rails. History Lloyd Mandeno, OBE (1888–1973) fully developed SWER in New Zealand around 1925 for rural electrification. Although he termed it "Earth Working Single ...
