Water and energy link in the cities of the future – achieving net zero carbon and pollution emissions footprint

摘要

This article discusses the link between water conservation, reclamation, reuse and energy use asnrelated to the goal of achieving the net zero carbon emission footprint in future sustainable cities.nIt defines sustainable ecocities and outlines quantitatively steps towards the reduction of energynuse due to water and used water flows, management and limits in linear and closed loop waterstormwater/wastewater management systems. The three phase water energy nexus diagram maynhave a minimum inflection point beyond which reduction of water demand may not result in anreduction of energy and carbon emissions. Hence, water conservation is the best alternativensolution to water shortages and minimizing the carbon footprint. A marginal water/energy chart isndeveloped and proposed to assist planners in developing future ecocities and retrofitting olderncommunities to achieve sustainability.
