The Energy-Water Nexus: Rising Energy Costs Meet Vulnerable Water Supplies
According to Ted Jones, with Consortium for Energy Efficiency (CEE), and R. Neal Elliott, with the American Council for an Energy-Efficient Economy, in a 2002 paper, water and wastewater treatment facilities account for 35% of energy used in municipalities.
Robert Goldstein, a researcher at the Electric Power Research Institute (EPRI), addressed the issue of electric power and water sustainability at a US Department of Energy (DOE) regional workshop in November 2005. He said all regions of the United States are experiencing vulnerability to water shortages, while water availability is impacting electricity supply and demand and electricity grid topology.
According to Goldstein, the consequences of the growing electric power and water demands will require more intensive management of water resources, greater integration between water and energy planning, more watershed or regional planning, and new science and technology to meet these needs.
EPRI, in a large 2002 study, reported that no more than 4% of total energy use in the country is used to convey and treat water and wastewater, and that its growth will track population growth.
