Water Efficiency Saves Energy: Reducing Global Warming Through Water Use Strategies

The collection, distribution, and treatment of drinking water and wastewater nationwide consume tremendous amounts of energy and release approximately 116 billion pounds of carbon dioxide (CO2) per year -- as much global warming pollution each year as 10 million cars. The energy-water connection is particularly strong in the driest regions of the United States, such as the Southwest, where significant amounts of energy are used to import water. Solutions exist to cut both water and energy use. Through water efficiency measures, we can help to protect dry areas from drought, lower consumers' utility bills, and reduce global warming pollution.
