The Water/Energy Nexus: Saving Water Saves Energy & Reduces Emissions
Monday, August 02, 2010Water and energy are inextricably linked, now and forever. Water is required to supply energy and energy is required to supply of water. This dynamic is called “the water/energy nexus.”
It takes electric power to move water from one place to another, to pump it from rivers and groundwater, to treat it before use and to treat it (as wastewater) after use. Today, an estimated 1 kWh of electricity is required to treat and distribute 1,000 gallons of potable water. Multiply that by tens of billions of gallons, and you have a lot of energy use!
